Understanding the differences between bacteria and viruses is important because they affect our health differently. In this study guide, we'll explore the key distinctions between these two microorganisms. Section 1: Bacteria What are Bacteria? Bacteria are tiny, single-celled living organisms. They are found everywhere, including in soil, water, and inside our bodies. Shape and Structure: Bacteria have different shapes like rods, spheres, and spirals. They have a cell wall that surrounds their cell membrane. Reproduction: Bacteria reproduce by dividing in half, a process called binary fission. This allows them to multiply quickly. Living or Nonliving: Bacteria are considered living because they can grow, reproduce, and respond to their environment. Section 2: Viruses What are Viruses? Viruses are smaller than bacteria and are not considered living organisms. They are made up of genetic material (either DNA or RNA) surrounded by a protein coat. Shape and Structure: Viruses come in various shapes but are much simpler than bacteria. They lack the cell structures found in bacteria. Reproduction: Viruses cannot reproduce on their own. They need a host cell (like a human cell) to replicate and make more viruses. Living or Nonliving: Viruses are considered nonliving because they cannot perform life processes without a host cell. Section 3: Differences Now, let's compare bacteria and viruses: Size: Bacteria are larger than viruses. Living or Nonliving: Bacteria are living organisms. Viruses are non-living entities. Reproduction: Bacteria reproduce on their own through binary fission. Viruses need a host cell to replicate. Structure: Bacteria have complex structures with cell walls. Viruses are simpler, consisting of genetic material and a protein coat. Treatment: Bacterial infections are treated with antibiotics. Viral infections are typically managed with antiviral medications (if available) or through the body's immune response. Section 4: Examples Examples of bacteria-related and virus-related illnesses: Bacterial Infections: Strep throat, Urinary tract infections (UTIs), Tuberculosis Viral Infections: Influenza (Flu), Common cold, HIV/AIDS Conclusion: Understanding the differences between bacteria and viruses can help us stay healthy and make informed decisions about treatment. Remember that while bacteria can be both helpful and harmful, viruses rely on our cells to replicate and cause infections.

Explain how each Social Determinant of Health may impact a personâs health. Levels of Disease Prevention ⢠PRIMARY The goal is to avoid conditions altogether. ⢠SECONDARY The goal is early detection. ⢠TERTIARY The goal is to minimize the damage (manage). Define the following terms. Fads/Trends Sleep hygiene Driver safety Unit 2- Investigating Social Ecological Factors on Well-Being Socio-Ecological Model â The SEM examines how health behaviors form based on characteristics of individuals, communities, nations and levels in between. Each level overlaps with other levels signifying how the best public health strategies are those that encompass and target a wide range of perspectives. Interpersonal (personal) health vs. intrapersonal (relationship) health Health INEQUITY - systemic, ingrained and unjust barriers that prevent segments of the population from having the opportunity of health leading to health disparity. IMPLICIT BIAS - a form of bias that occurs automatically and unintentionally, that nevertheless affects judgments, decisions, and behaviors. Research has shown implicit bias can contribute to unequal access to quality healthcare, negative patient-provider relationships and interactions; and create mistrust in the healthcare system and practitioners among patients. This can contribute to health disparities. Health DISPARITY - represents a difference in health between populations. It is often used to describe disease burden and other negative health outcomes socially disadvantaged groups may face. Health EQUITY - The opposite of health inequity. It describes a system that supports a high standard of health and healthcare for all people. Racism - Beliefs, attitudes, institutional arrangements, and acts that tend to denigrate individuals or groups because of phenotypic characteristics or ethnic group affiliation. DISCRIMINATION - An unjust differential treatment of a person or a group. PRIVILEGE- The unearned access to resources and social power that are only available to some because of their membership within certain social groups. OPPRESSION is the act of taking away choices from others and can be defined as a system that maintains advantage and disadvantage based on social identities and that acts on multiple levels from interpersonal to institutional and societal. (internalized, interpersonal, institutional, structural) Systematic Oppression - Intentional disadvantage of groups of people based on their identity while advantaging members of dominant group (race, gender, sexual orientation, language, size, ability, etc.). Intersectionality - The complex, cumulative way in which the effects of multiple forms of discrimination (such as racism, sexism, and classism) combine, overlap, or intersect especially in the experiences of marginalized individuals or groups Unit 3- Accessing Resources and Communicating to Support Mental and Emotional Health What is anger? What is anxiety? What is stress? STRESSORS are the things that cause stress. Stressors can be internal and external. A stressor may be a one-time or short-term occurrence, or it can happen repeatedly over a long time. INTERNAL Stressors - are made by your belief system and the way you evaluate yourself. Examples include pessimistic attitude, negative self-talk, deep need to be perfect, low self-esteem or body image, unhealthy standards for self. EXTERNAL Stressors - are stressful things that happen in your surroundings and/or in your environment. Examples include busy schedules, work problems, family issues, financial trouble, social problems, injury, unforeseen circumstances. Socio-economic issues are also a part of external stressors such as poverty, violence, and racism. Define the following mental health conditions. Depression Eating disorders NSSI Non-suicidal self-injury Grief/Loss Suicide prevention A.C.T. ⢠ACKNOWLEDGE- Tell them in a caring way that you recognize that they are having a problem ⢠CARE- You can show you care by actively listening - put away anything else you are doing, make eye contact, sit down, ask questions. ⢠TELL-(call 988 for additional help and support) - Tell them it is important that they speak with a trusted adult. Help them figure out who this may be and offer to go with your friend. A social norm is an unwritten, informal rule meant to guide behavior among the of society. It distinguishes between acceptable and unacceptable, good and bad, and so on. Social norms can influence a person with emotional or mental health disorders, access to care and stigmatize their situation. STIGMA- a mark of disgrace associated with a particular circumstance, quality, or person. ⢠Self-stigma - This describes the internalized stigma that people with mental health conditions feel about themselves. ⢠Public stigma - This refers to the negative attitudes around mental health from people in society. ⢠Institutional stigma - This is a type of systemic stigma that arises from corporations, governments, and other institutions. Unit 4- Evaluating Risks of Substance Use and Abuse Harm Reduction - a set of practical strategies and ideas aimed at reducing negative consequences associated with drug use. Explain how each level of the Social Ecological Model is impacted by addiction. Individual Relationship Community Society SEM Level Contributing/Risk Factors to substance use Preventative/Protective Factors for substance use Individual Interpersonal/Relationship Community Society Unit 5- Analyzing Influences to Examine Ways to Increase Safety and Reduce Violence HATE CRIME - a crime, usually violent, motivated by prejudice or intolerance toward an individualâs national origin, ethnicity, color, religion, gender, gender identity, sexual orientation, or disability. Explain how the media influences violence in society. The Pyramid of Hate Explain the escalation of hate using the Pyramid of Hate visual. List several hate crime motivators. Example: age HEALTHY Relationship Signs - comfortable pace, trust, honesty, independence, respect, equality, kindness, taking responsibility, healthy conflict, fun UNHEALTHY Relationship Signs - intensity, possessiveness, manipulation, isolation, sabotage, belittling, guilting, volatility, deflecting responsibility, betrayal Sexual Assault is a sexual behavior WITHOUT consent. Human trafficking - the recruitment, harboring, transportation, provision, or obtaining of a person for labor or services, using force, fraud, or coercion for the purpose of subjection to involuntary servitude, peonage, debt bondage, or slavery. Sex trafficking - commercial sex act induced by force, fraud, or coercion, or in which the person induced to perform such an act has not attained 18 years of age. Trafficking happens using⌠⢠Force - using violence to control someone. ⢠Fraud - using lies to control someone. ⢠Coercion - using threats to control someone. Unit 6- Family Life and Human Sexuality Agency - A belief about yourself and the extent to which you can act on that belief. ⢠The ability to choose freely oneâs own narrative. ⢠To embrace the idea that I am the cause (or agent) of my own thoughts and actions. ⢠Personal agency is a personal responsibility for who we are, what we experience, what we do about that experience, and how we shape our world to give us more of the experiences we want. SEXUAL Agency ⢠The ability to choose your own interests and desires vs. what we see in the media or othersâ perceptions ⢠The ability to identify, communicate, and negotiate oneâs sexual needs ⢠The ability to initiate behaviors that allow for the satisfaction of those needs Sexually Explicit Material - photographs, videos, films, magazines, and books whose primary themes, topics, or depictions involve sexuality that may cause sexual arousal. Sexual scripts - thoughts, patterns, or behavior that a person has about themselves in a romantic or sexual context. It is how people picture themselves or want to project themselves in front of others. Reproductive Rights of Teens - In Maryland, teens have the right to an abortion, keep their child, obtain and use birth control, paternity tests, adoption, give up custody of their child within 10 days of birth (Safe Haven Law). ⢠REPRODUCTIVE RIGHTS- legal rights and the freedom of the individual to control decisions regarding contraception, abortion, sterilization and childbirth. ⢠SAFE HAVEN LAW- a distressed parent who is unable or unwilling to care for their infant can safely give up custody of their baby, no questions asked. CONSENT is an agreement between participants to engage in sexual activity. ⢠It is clearly and freely communicated, verbal, and affirmative. Consent CANNOT be given if⌠⢠A person is underage, one or both partners is intoxicated or incapacitated by drugs or alcohol, one partner is asleep or unconscious, one partner feels pressured, threatened or intimidated, or one partner holds a position of power or authority over the other.

FOOD INSEQURITY lack of access to a sufficient amount of food because of limited funds. More than 49 million American households are considered food insecure and are vulnerable to poor health as a result. PROCCESED FOODS- any raw agricultural commodities that have been washed, cleaned, milled, cut, chopped, heated, pasteurized, blanched, cooked, canned, frozen, dried, dehydrated, mixed or packaged â anything done to them that alters their natural state.
2.2 Study Guide [ 2.2 Sequence Assessment 1/21 and 1/22] Ecosystems and Ecological Relationships Invasive Species â An invasive species is a plant, animal, or organism that is not native to a specific area and causes harm to the environment or human health. Why are they harmful? Invasive species often outcompete native species for food, water, and space. They can spread quickly because they lack natural predators in the new environment. What is their impact on the ecosystem? Invasive species can reduce biodiversity by pushing native species to extinction or by changing the habitat in which native species live. Biodiversity and Its Importance to Ecosystems Biodiversity refers to the variety of life in a specific area, including different species of plants, animals, and microorganisms, and the ecosystems they form. â Stability: Biodiversity makes ecosystems more resilient to changes such as climate change, diseases, and natural disasters. â Food chains and webs: A greater variety of species means more sources of food for different animals, helping maintain a balanced food web. For example, a forest with many species of plants and animals can recover from a drought more easily than a forest with fewer species. Predator-Prey Relationships In a predator-prey relationship, one organism (the predator) hunts and eats another organism (the prey). The predator benefits by getting food, while the prey loses its life.The population sizes of predators and prey are often linked. If there are more prey, the predator population may grow, but if too many predators eat the prey, the predator population will decrease. This relationship can be shown in the graph below. â For example: Lions hunt zebras for food. When there are many zebras, lions have more food and their population can grow. However, if too many lions eat the zebras, the zebra population can decrease. Predator-prey relationships help keep animal populations balanced, preventing one species from becoming too numerous and harming the environment. Ecological Relationships There are several types of relationships between organisms in an ecosystem. These include commensalism, parasitism, and mutualism. Commensalism In commensalism, one organism benefits from the relationship while the other is neither helped nor harmed. An example would be Barnacles and Whales. Barnacles attach to the skin of whales. The barnacles get access to nutrient-rich water while the whale swims, but the whale is not affected by their presence. Parasitism In parasitism, one organism (the parasite) benefits at the expense of the other organism (the host), which is harmed. For example, fleas live on dogs and feed on their blood. The fleas benefit, but the dog may suffer from itching, infections, or even anemia. Another example are tapeworms and humans. Tapeworms live in the intestines of humans and absorb nutrients, leaving the human host malnourished. Mutualism In mutualism, both organisms benefit from the relationship. An example would be bees and flowers: Bees collect nectar from flowers to make honey, while helping the flowers by transferring pollen, which helps them reproduce.
Lipids are large, nonpolar organic molecules. They do not dissolve in water. Lipids include triglycerides (trie-GLIS-uhr-IEDZ), phospho- lipids, steroids, waxes, and pigments. Lipid molecules have a higher ratio of carbon and hydrogen atoms to oxygen atoms than carbohydrates have. Because lipid molecules have larger numbers of carbon-hydrogen bonds per gram than other organic com- pounds do, they store more energy per gram. Fatty Acids Fatty acids are unbranched carbon chains that make up most lipids. Figure 3-10 shows that a fatty acid contains a long carbon chain (from 12 to 28 carbons) with a carboxyl group, âCOOH, attached at one end. The two ends of the fatty-acid molecule have different properties. The carboxyl end is polar and is thus hydrophilic or attracted to water molecules. In contrast, the hydro- carbon end of the fatty-acid molecule is nonpolar. This end tends not to interact with water molecules and is said to be hydrophobic (HIE-droh-FOH-bik), or âwater fearing.â In saturated fatty acids, such as palmitic acid, which is shown in Figure 3-10, each carbon atom is covalently bonded to four atoms. The carbon atoms are in effect full, or saturated. In contrast, linoleic acid, also shown in Figure 3-10, has carbon atoms that are not bonded to the maximum number of atoms to which they can bond. Instead, they have formed double bonds within the carbon chain. This type of fatty acid is said to be unsaturated. Triglycerides Three classes of lipids important to living things contain fatty acids: triglycerides (fats), phospholipids, and waxes. A triglyceride is composed of three molecules of fatty acid joined to one molecule of the alcohol glycerol. Saturated triglycerides are composed of saturated fatty acids. They typically have high melting points and tend to be hard at room temperature. Common dietary saturated triglycerides include butter and fats in red meat. In contrast, unsaturated triglycerides are composed of unsaturated fatty acids and are usually soft or liquid at room temperature. Unsaturated triglycerides are found primarily in plant seeds where they serve as an energy and carbon source for germinating plants. Phospholipids Phospholipids have two, rather than three, fatty acids attached to a molecule of glycerol. They have a phosphate group attached to the third carbon of the glycerol. As shown in Figure 3-11, the cell membrane is made of two layers of phospholipids, called the lipid bilayer. The inability of lipids to dissolve in water allows the mem- brane to form a barrier between the inside and outside of the cell. Hydrophilic âheadâ Phospholipids Hydrophobic âtailâ Phospholipids Water Water The lipid bilayer of a cell membrane is a double row of phospholipids.The âtailsâ face each other.The âheadâ of a phospholipid, which contains a phosphate group, is polar and hydrophilic.The two tails are two fatty acids and are nonpolar and hydrophobic.

Applying Information You want to eat more unsaturated than saturated fats. Name examples of foods you would eat more of and less of. SECTION 2 REVIEW Waxes A wax is a type of structural lipid consisting of a long fatty-acid chain joined to a long alcohol chain. Waxes are waterproof, and in plants, form a protective coating on the outer surfaces. Waxes also form protective layers in animals. For example, earwax helps pre- vent microorganisms from entering the ear canal. Steroids Unlike most other lipids, which are composed of fatty acids, steroid molecules are composed of four fused carbon rings with various functional groups attached to them. Many animal hor- mones, such as the male hormone testosterone, are steroid com- pounds. One of the most familiar steroids in humans is cholesterol. Cholesterol is needed by the body for nerve and other cells to func- tion normally. It is also a component of the cell membrane. NUCLEIC ACIDS Nucleic acids are very large and complex organic molecules that store and transfer important information in the cell. There are two major types of nucleic acids: deoxyribonucleic acid and ribonucleic acid. Deoxyribonucleic acid, or DNA, contains information that deter- mines the characteristics of an organism and directs its cell activi- ties. Ribonucleic (RIE-boh-noo-KLEE-ik) acid, or RNA, stores and transfers information from DNA that is essential for the manufactur- ing of proteins. Some RNA molecules can also act as enzymes. Both DNA and RNA are polymers, composed of thousands of linked monomers called nucleotides (NOO-klee-uh-TIEDS). As shown in Figure 3- 12, each nucleotide is made of three main components: a phosphate group, a five-carbon sugar, and a ring-shaped nitrogenous base.
7.03 Patients with Infectious Disease The center adheres to infection control policies to ensure the safety of patients, physicians, and staff members. Patients who are currently being treated for an infectious disease or condition that is transmitted via the contact route may not be treated at the center. Patients with disease spread via droplet (e.g. influenza) or airborne (e.g. tuberculosis, measles) routes will reschedule their procedures in consultation with their physicians. The infection control nurse, in consultation with the infection control consultant, will determine whether the patient requires isolation or other additional precautions. If a patient with current Clostridium difficile-associated diarrhea is treated at the center, all rooms where the patient was housed, even briefly, should be cleaned by housekeeping under supervision of the staff at the center. Physicians must document relevant information in their pre-admission documentation. Standard Precautions will be followed in the care of all patients. Cigarroa Interventional Institute establishes policies to ensure compliance with infection control policies for the care of patients with drug-resistant organisms. The physician will screen patients through the medical history review prior to scheduling a patient at the center. During the pre-operative (pre-op) phone call or interview, a pre-op screening of the patient will be conducted. Strict isolation policies are required to treat patients with active MRSA, VRSA, or tuberculosis. Since this facility has no provisions for strict isolation, those patients with active infections will be referred elsewhere for treatment. Patients who are undergoing or completed a course of antibiotic therapy, are colonized and/or are not actively infected may be treated at the center. Patients with active infections requiring transmission-based precautions are not appropriate candidates for this facility and will be referred to another facility or rescheduled. Procedures cannot be scheduled for patients currently undergoing an infection with transmission based precautions. The patient must finish the course, and they will be rescheduled. Definitions and Standards: The following definitions and standards are provided for informational purposes only: Airborne Transmission and Precautions: This mode of transmission occurs by the spreading of either airborne droplet nuclei (small particle residue of 5 microns or smaller), of evaporated droplets which contain microorganisms that remain suspended in the air for long periods of time) or dust particles containing microorganisms. Patients must be isolated in private rooms with special air handling and ventilation, and the door must remain closed. Patient transport should be restricted to essential transport only. Respiratory precautions must be taken when in the presence of patients with active tuberculosis, including respiratory masks. Droplet Transmission and Precautions: Droplets are transmitted from the host source by coughing, sneezing, talking, or during procedures such as suctioning or bronchoscopy. Patients must be isolated, and a distance of 3 feet maintained between the infected patient and others. Caregivers within 3 feet of the patient should wear a mask. Patient transport should be minimized. Contact Transmission and Precautions: Direct contact transmission involves direct body surface to body surface contact with physical transfer of microorganisms between a susceptible host and an infected person. Indirect contact transmission involves contact with an intermediate object (usually inanimate) and a susceptible host. Patients should be isolated as much as possible. Gloves and hand washing are essential for all contact with the patient and contact with objects, which come in contact with the patient. Gloves should be changed after each contact. Reportable Condition If the patient is determined to have a reportable condition at any time during pre-admission, the Director of Operations/Nurse Manager will be notified. The procedural physician will be contacted and the case will be canceled. The Department of Health will also be notified the same day following state regulations regarding Reportable Communicable Diseases. To report a disease or condition, contact: The City of Laredo Epidemiology 24/7 Reporting Line: (956) 763-2915, if unable to report locally, call The Texas Departmrent of Health Services epidemiology program: 24/7Number for Immediately Reportable â 1-800-705-8868
Acetic acid â a chemical substance with an inhibiting effect on the growth of microorganisms and which is present in vinegar.Acetic Acid Fermentation Fermentation preserves food through the metabolic activities of selected groups of microorganisms. During the process, compounds such as lactic acid, acetic acid and alcohol are developed and result in a more or less stable food form. It makes food more nutritious as dietary source of proteins, vitamins and minerals.Vinegar is an example of the product of acetic acid fermentation which also undergoes alcoholic fermentation to complete the process.Filter â is a device, substance (like paper or charcoal), or process that separates unwanted components from a fluid Cheesecloth-is a loose-woven, gauze-like cotton fabric used for straining liquids from solids.Decant- gradually pour (liquid, typically wine or a solution) from one container into another, especially without disturbing the sediment. Sediment-is solid material (like sand, silt, clay, rocks, organic matter) broken down by weathering, transported by wind, water, or ice, and deposited in a new location, settling at the bottom of water bodies or on land.How to make vinegar?1.Grind or crash the fruit, then boil in water of the same amount as the ground flesh, peels and cores. Boil until soft, and then strain the juice through a cheesecloth2.Add Âź (one-fourth) pound of sugar for every liter of juice extracted from fruit peels and cores. Do not add sugar when using ripe fruit.3.Add Âź of a cake of fresh yeast that has been well-broken up, for every liter of juice. Stir very well, and then place in glass jars. Cover with a clean cloth and let the mixture stand for about two weeks .4. After two weeks, separate the clear liquid from the sediment. Prepare fresh, unpasteurized vinegar also called âmother vinegarâ which is the white gummy mass that usually forms in vinegar. Add this to the liquid and mix very well.

Make a test, with answers best on the following: Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells. Supporting Content LS1.A: Structure and Function ⢠All living things are made up of cells, which is the smallest unit that can be said to be alive. An organism may consist of one single cell (unicellular) or many different numbers and types of cells (multicellular). (MS-LS-1.1) Further Explanation: Emphasis is on developing evidence that living things are made of cells, distinguishing between living and non-living things, and understanding that living things may be made of one cell or many and varied cells. In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions. (MS-LS-1.3) Further Explanation: Emphasis is on the conceptual understanding that cells form tissues and tissues form organs specialized for particular body functions. Examples could include the interaction of subsystems within a system and the normal functioning of those systems. Organisms reproduce, either sexually or asexually, and transfer their genetic information to their offspring. (MS-LS-1.4) ⢠Living things share certain characteristics. (These include response to environment, reproduction, energy use, growth and development, life cycles, made of cells, etc.) (MS-LS1.4) Further Explanation: Examples should include both biotic and abiotic items, and should be defended using accepted characteristics of life. Plants, algae (including phytoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of photosynthesis, which also releases oxygen. These sugars can be used immediately or stored for growth or later use. (MS-LS-1.5) Further Explanation: Emphasis is on tracing movement of matter and flow of energy. Supporting Content LS1.C: Organization for Matter and Energy Flow in Organisms ⢠Within individual organisms, food moves through a series of chemical reactions (cellular respiration) in which it is broken down and rearranged to form new molecules, to support growth, or to release energy. (MS-LS-1.6) Further Explanation: Emphasis is on describing that molecules are broken apart and put back together and that in this process, energy is released and on understanding that the elements in the products are the same as the elements in the reactants. Organisms, and populations of organisms, are dependent on their environmental interactions both with other living things and with nonliving factors. (MS-LS-2.1) ⢠In any ecosystem, organisms and populations with similar requirements for food, water, oxygen, or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction. (MS-LS-2.1) ⢠Growth of organisms and population increases are limited by access to resources. (MS-LS-2.1) Further Explanation: Emphasis is on cause and effect relationships between resources and growth of individual organisms and the numbers of organisms in ecosystems during periods of abundant and scarce resources. Similarly, predatory interactions may reduce the number of organisms or eliminate whole populations of organisms. Mutually beneficial interactions, in contrast, may become so interdependent that each organism requires the other for survival. Although the species involved in these competitive, predatory, and mutually beneficial interactions vary across ecosystems, the patterns of interactions of organisms with their environments, both living and nonliving, are shared. (MS-LS-2.2) Further Explanation: Emphasis is on predicting consistent patterns of interactions in different ecosystems in terms of the relationships among and between organisms and abiotic components of ecosystems. Examples of types of interactions could include competitive, predatory, and mutually beneficial. Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem. (MS-LS-2.3) Further Explanation: Emphasis is on describing the conservation of matter and flow of energy into and out of various ecosystems, and on defining the boundaries of the system. Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations. (MSLS-2.5) Further Explanation: Emphasis is on recognizing patterns in data and making warranted inferences about changes in populations, and on evaluating empirical evidence supporting arguments about changes to ecosystems. Biodiversity describes the variety of species found in Earthâs terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystemâs biodiversity is often used as a measure of its health. (MS-LS-2.6) Supporting Content LS4.D: Biodiversity ⢠Changes in biodiversity can influence humansâ resources, such as food, energy, and medicines, as well as ecosystem services that humans rely onâfor example, water purification and recycling. (MS-LS-2.6) Supporting Content ETS1.B: Developing Possible Solutions ⢠There are systematic processes for evaluating solutions with respect to how well they meet the criteria and constraints of a problem. (MS-LS-2.6) Further Explanation: Examples of ecosystem services could include water purification, nutrient recycling, and prevention of soil erosion. Examples of design solution constraints could include scientific, economic, and social considerations. Genes are located in the chromosomes of cells, with each chromosome pair containing two variants of each of many distinct genes. Each distinct gene chiefly controls the production of specific proteins, which in turn affects the traits of the individual. Structural changes to genes (mutations) can result in changes to proteins, which can affect the structures and functions of the organism and thereby change traits. (MS-LS-3.1) Supporting Content LS3.B: Variation of Traits ⢠In addition to variations that arise from sexual reproduction, genetic information can be altered because of mutations. Though rare, mutations may result in significant changes to the structure and function of proteins. Changes can be beneficial, harmful, or neutral to the organism. (MS-LS-3.1) Further Explanation: Emphasis is on conceptual understanding that changes in genetic material may result in making different proteins. Organisms reproduce, either sexually or asexually, and transfer their genetic information to their offspring. (MS-LS-3.2) Supporting Content LS3.A: Inheritance of Traits ⢠Variations of inherited traits between parent and offspring arise from genetic differences that result from the subset of chromosomes (and therefore genes) inherited. (MS-LS-3.2) Supporting Content LS3.B: Variation of Traits ⢠In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other. (MS-LS-3.2) Further Explanation: Emphasis is on using models such as simple Punnett squares and pedigrees, diagrams, and simulations to describe the cause and effect relationship of gene transmission from parent(s) to offspring and resulting genetic variation. The collection of fossils and their placement in chronological order is known as the fossil record and documents the change of many life forms throughout the history of the Earth. Anatomical similarities and differences between various organisms living today and between living and once living organisms in the fossil record enable the classification of living things. (MS-LS-4.1, MS-LS-4.2) Further Explanation: Emphasis is on finding patterns of changes in the level of complexity of anatomical structures in organisms and the chronological order of fossil appearance in the rock layers. The collection of fossils and their placement in chronological order is known as the fossil record and documents the change of many life forms throughout the history of the Earth. Anatomical similarities and differences between various organisms living today and between living and once living organisms in the fossil record enable the classification of living things. (MS-LS-4.1, MS-LS-4.2) Further Explanation: Emphasis is on explanations of the relationships among organisms in terms of similarity or differences of the gross appearance of anatomical structures. Scientific genus and species level names indicate a degree of relationship. (MS-LS-4.3) Further Explanation: Emphasis is on inferring general patterns of relatedness among structures of different organisms by comparing diagrams, pictures, specimens, or fossils. Natural selection leads to the predominance of certain traits in a population, and the suppression of others. (MS-LS-4.4) Further Explanation: Emphasis is on using concepts of natural selection, including overproduction of offspring, passage of time, variation in a population, selection of favorable traits, and heritability of traits. In artificial selection, humans have the capacity to influence certain characteristics of organisms by selective breeding. One can choose desired parental traits determined by genes, which are then passed to offspring. (MS-LS-4.5) Further Explanation: Emphasis is on identifying and communicating information from reliable sources about the influence of humans on genetic outcomes in artificial selection (such as genetic modification, animal husbandry, gene therapy), and on the influence these technologies have on society as well as the technologies leading to these scientific discoveries. Adaptation by natural selection acting over generations is one important process by which species change over time in response to changes in environmental conditions. Traits that support successful survival and reproduction in the new environment become more common; those that do not become less common. Thus, the distribution of traits in a population changes. (MS-LS-4.6) Further Explanation: Emphasis is on using mathematical models, probability statements, and proportional reasoning to support explanations of trends in changes to populations over time. Examples could include Peppered Moth population changes before and after the industrial revolution.
7.018 Safe Injection Practices (Refer to 7.07 Safe Injection Policy) Environment of Care: Active participation with all identified projects to assess compliance with infection control standards. . Surveillance, Control, and Reporting includes: Baseline information about the frequency and type of nosocomial infections. Identification of patients and/or staff with communicable or potentially communicable infections. Patients identified with a communicable disease will be isolated from other patients in the facility or, if this is not possible, they will be transferred to a local hospital for care or rescheduled. Identification of clusters of microorganisms or significant deviations from endemic level. Reporting to committees and outside agencies, when required. Investigation of infections as needed. Immediate implementation of corrective and preventive measures that result in improvements. The Infection Control nurse or designated staff member will perform facility audits and report results to the QI committee and Board of Managers. EVALUATION Evaluation and improvement of the infection prevention and control activities are important steps in the Centerâs efforts to control and prevent infection. Infection prevention and control practices should become a routine part of the care, treatment, or services the center provides to patients. Patients expect and deserve hygienic and safe care even if their contact with the Center does not extend beyond a single visit. Continuous review of the goals, activities, and outcomes of the Centerâs initiative are therefore followed by improvement activities that are realistic in expectation and, above all, effective. Evaluation of the plan shall include but not be limited to: Evaluation of the infection prevention and control activities annually and whenever risks significantly change. The evaluation includes a review of the following: The infection prevention and control prioritized risks The infection prevention and control goals. Implementation of infection prevention and control Outcomes of infection prevention and control activities. Findings from the evaluation are communicated at least annually to the Quality Management Committee References: http://oneandonlycampaign.org/content/what-are-they-why-follow-them.
