Living and non living life process

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.

Content guide: Include the presentation title, group members’ names, course/module name, and date. Speaker guide: Briefly say that the presentation explains what employees and companies should consider before sending someone on secondment to Thailand. Slide 2: Agenda / Overview Welcome everyone. Our presentation is about secondments in Thailand. We will cover the main areas that a company and employee should prepare for before relocation. These include finance and housing, work culture, legal and visa requirements, healthcare and safety, and daily logistics such as transport and climate. By the end of the presentation, we hope to show that a successful secondment depends not only on the job itself, but also on good planning before and after arrival in Thailand. Slide 3: What Is a Secondment? A secondment is a temporary work assignment where an employee is transferred to another country, branch, client site, or partner organization while usually remaining connected to the original employer. Secondments require coordination between the employee, home employer, host organization, and local authorities. Slide 4: Finance & Housing — Cost of Living Finance and housing are one of the first things a secondee should plan before moving to Thailand. The cost of living can vary a lot depending on whether the employee is based in Bangkok, another major city, or a regional area. Urban areas usually have higher rent, but they also offer better access to transport, hospitals, offices, and international services. In smaller cities or rural areas, rent may be lower, but transport and convenience can become bigger concerns. So, the key point is that secondees should not only compare prices, but also consider location, commute, and what support the employer provides. Slide 6: Work Culture — Hierarchy & Etiquette Purpose: Help secondees understand workplace expectations. Content guide: Cover respect for seniority, polite communication, indirect feedback, saving face, punctuality, proper greetings, and professional dress. Speaker guide: Explain that foreign employees should avoid being too blunt in meetings and should observe how local colleagues communicate with managers or senior staff. Suggested visual: “Do and Don’t” etiquette list. Slide 7: Work Culture — Industry Growth & Networking Purpose: Connect secondments to career and business opportunities. Content guide: Mention sectors where Thailand often attracts foreign professionals, such as manufacturing, tourism, logistics, finance, technology, and regional business operations. Discuss relationship-building and networking. Speaker guide: Emphasize that trust and long-term relationships are important in Thai professional settings. Networking can happen through industry events, chambers of commerce, company introductions, and informal business meals. Suggested visual: Thailand industry opportunity map or sector icons. Slide 8: Legal & Immigration — Visa Pathways Purpose: Explain the main legal entry pathway for work-related secondments. Content guide: Introduce the Non-Immigrant B visa as a common work/business visa category. Mention that supporting documents may include passport, application forms, employment or company letters, and other evidence requested by Thai authorities. Speaker guide: Make clear that a visa alone may not be enough to legally work; seconded employees normally need the correct visa and work authorization. The exact process depends on the employer, role, nationality, and assignment structure. Suggested visual: Simple flowchart: Home employer → Host company → Visa application → Arrival → Work permit/compliance. Slide 9: Legal & Immigration — Compliance Rules Purpose: Explain ongoing responsibilities after arrival. Content guide: Cover visa extensions, work permit validity, re-entry permits, address reporting, and 90-day reporting for eligible long-stay foreigners. Speaker guide: Stress that compliance is not a one-time task. Employees and HR teams should track deadlines carefully because missing reporting or renewal dates can cause fines, delays, or legal issues. Suggested visual: Compliance checklist or timeline. Slide 10: Healthcare & Public Safety Purpose: Explain how secondees should prepare for health and safety risks. Content guide: Cover international health insurance, access to private hospitals, emergency numbers, vaccinations or health checks if required, and common local hazards such as road safety, flooding, heat, food hygiene, and mosquito-borne illnesses. Speaker guide: Explain that Thailand has strong healthcare options in major cities, but employees should confirm insurance coverage before arrival. They should also know what to do in an emergency and save important contact numbers. Suggested visual: Emergency preparation checklist. Slide 11: Logistics & Climate Purpose: Explain practical relocation and daily-life planning. Content guide: Cover public transit, taxis, ride-hailing, domestic travel, airport access, SIM cards, banking, weather, rainy season, heat, and packing needs. Speaker guide: Mention that weather affects commuting, clothing, housing choice, and travel planning. Employees should plan around heat, rain, and possible flooding, especially during the rainy season. Suggested visual: Seasonal calendar showing hot, rainy, and cool periods. Slide 12: Project Manager / Group Synthesis Purpose: Bring the presentation together and end with key recommendations. Content guide: Summarize the main risks and preparation steps: budget early, secure compliant visa/work permit arrangements, understand workplace culture, arrange insurance, and prepare for climate/logistics. Speaker guide: Conclude by saying that a successful secondment in Thailand depends on both professional readiness and personal relocation planning. End with 3–5 recommendations for companies and employees. Suggested visual: Final checklist: “Before departure,” “Upon arrival,” and “During secondment.” A simple way to divide the work is: Member 1: Slides 1–3 introduction. Member 2: Slides 4–5 finance and housing. Member 3: Slides 6–7 work culture. Member 4: Slides 8–9 legal and immigration. Member 5: Slides 10–12 healthcare, logistics, and conclusion.

CHARACTERISTICS OF LIFE The world is filled with familiar objects, such as tables, rocks, plants, pets, and automobiles. Which of these objects are living or were once living? What are the criteria for assigning something to the living world or the nonliving world? Biologists have established that living things share seven characteristics of life. These characteristics are organization and the presence of one or more cells, response to a stimulus (plural, stimuli), homeostasis, metabolism, growth and development, reproduction, and change through time. Organization and Cells Organization is the high degree of order within an organism’s internal and external parts and in its interactions with the living world. For example, compare an owl to a rock. The rock has a spe- cific shape, but that shape is usually irregular. Furthermore, differ- ent rocks, even rocks of the same type, are likely to have different shapes and sizes. In contrast, the owl is an amazingly organized individual, as shown in Figure 1-2. Owls of the same species have the same body parts arranged in nearly the same way and interact with the environment in the same way. Copyright © by Holt, Rinehart and Winston. All rights reserved. ORGANISM (Barn Owl) ORGAN (Owl’s Ear) TISSUE (Nervous Tissue Within the Ear) CELL (Nerve Cell) Every living organism has a level of organization. The different levels of organization for a complex multicellular organism, such as an owl, are shown in the figure below. FIGURE 1-2 THE SCIENCE OF LIFE 7 All living organisms, whether made up of one cell or many cells, have some degree of organization. A cell is the smallest unit that can perform all life’s processes. Some organisms, such as bacteria, are made up of one cell and are called unicellular (YOON-uh-SEL-yoo-luhr) organisms. Other organisms, such as humans or trees, are made up of multiple cells and are called multicellular (MUHL-ti-SEL-yoo-luhr) organisms. Complex multicellular organisms have the level of orga- nization shown in Figure 1-2. In the highest level, the organism is made up of organ systems, or groups of specialized parts that carry out a certain function in the organism. For example, an owl’s ner- vous system is made up of a brain, sense organs, nerve cells, and other parts that sense and respond to the owl’s surroundings. Organ systems are made up of organs. Organs are structures that carry out specialized jobs within an organ system. An owl’s ear is an organ that allows the owl to hear. All organs are made up of tissues. Tissues are groups of cells that have similar abilities and that allow the organ to function. For example, nervous tissue in the ear allows the ear to detect sound. Tissues are made up of cells. A cell must be covered by a membrane, contain all genetic information necessary for replication, and be able to carry out all cell functions. Within each cell are organelles. Organelles are tiny structures that carry out functions necessary for the cell to stay alive. Organelles contain biological molecules, the chemical compounds that provide physical structure and that bring about movement, energy use, and other cellular functions. All biological molecules are made up of atoms. Atoms are the simplest particle of an ele- ment that retains all the properties of a certain element. Response to Stimuli Another characteristic of life is that an organism can respond to a stimulus—a physical or chemical change in the internal or external environment. For example, an owl dilates its pupils to keep the level of light entering the eye constant. Organisms must be able to respond and react to changes in their environment to stay alive. ORGANELLE (Mitochondrion) BIOLOGICAL MOLECULE (Phospholipid) ATOM (Oxygen) cell from the Latin, cella meaning “small room,” or “hut” Word Roots and Origins www.scilinks.org Topic: Characteristics of Life Keyword: HM60257 mb06se_bios01.qxd 5/18/07 10:37 AM Page 7 8 CHAPTER 1 Homeostasis All living things, from single cells to entire organisms, have mecha- nisms that allow them to maintain stable internal conditions. Without these mechanisms, organisms can die. For example, a cell’s water content is closely controlled by the taking in or releas- ing of water. A cell that takes in too much water will rupture and die. A cell that doesn’t get enough water will also shrivel and die. Homeostasis (HOH-mee-OH-STAY-sis) is the maintenance of a stable level of internal conditions even though environmental conditions are constantly changing. Organisms have regulatory systems that maintain internal conditions, such as temperature, water content, and uptake of nutrients by the cell. In fact, multi- cellular organisms usually have more than one way of maintain- ing important aspects of their internal environment. For example, an owl’s temperature is maintained at about 40°C (104°F). To keep a constant temperature, an owl’s cells burn fuel to produce body heat. In addition, an owl’s feathers can fluff up in cold weather. In this way, they trap an insulating layer of air next to the bird’s body to maintain its body temperature. Metabolism Living organisms use energy to power all the life processes, such as repair, movement, and growth. This energy use depends on metabolism (muh-TAB-uh-LIZ-uhm). Metabolism is the sum of all the chemical reactions that take in and transform energy and materials from the environment. For example, plants, algae, and some bacteria use the sun’s energy to generate sugar molecules during a process called photosynthesis. Some organisms depend on obtaining food energy from other organisms. For instance, an owl’s metabolism allows the owl to extract and modify the chemi- cals trapped in its nightly prey and use them as energy to fuel activities and growth. Growth and Development All living things grow and increase in size. Some nonliving things, such as crystals or icicles, grow by accumulating more of the same material of which they are made. In contrast, the growth of living things results from the division and enlargement of cells. Cell division is the formation of two new cells from an existing cell, as shown in Figure 1-3. In unicellular organisms, the primary change that occurs following cell division is cell enlargement. In multi- cellular life, however, organisms mature through cell division, cell enlargement, and development. Development is the process by which an organism becomes a mature adult. Development involves cell division and cell differen- tiation, or specialization. As a result of development, an adult organism is composed of many cells specialized for different func- tions, such as carrying oxygen in the blood or hearing. In fact, the human body is composed of trillions of specialized cells, all of which originated from a single cell, the fertilized egg. This unicellular organism, Escherichia coli, inhabits the human intestines. E. coli reproduces by means of cell division, during which the original cell splits into two identical offspring cells. FIGURE 1-3 Observing Homeostasis Materials 500 mL beakers (3), wax pen, tap water, thermometer, ice, hot water, goldfish, small dip net, watch or clock with a second hand Procedure 1. Use a wax pen to label three 500 mL beakers as follows: 27°C (80°F), 20°C (68°F), 10°C (50°F). Put 250 mL of tap water in each beaker. Use hot water or ice to adjust the tem- perature of the water in each beaker to match the temperature on the label. 2. Put the goldfish in the beaker of 27°C water. Record the number of times the gills move in 1 minute. 3. Move the goldfish to the beaker of 20°C water. Repeat observations. Move the goldfish to the beaker of 10°C. Repeat observations. Analysis What happens to the rate at which gills move when the temp- erature changes? Why? How do gills help fish maintain homeostasis? Quick Lab mb06se_bios01.qxd 5/18/07 10:37 AM Page 8 THE SCIENCE OF LIFE 9 Reproduction All organisms produce new organisms like themselves in a process called reproduction. Reproduction, unlike other characteristics, is not essential to the survival of an individual organism. However, because no organism lives forever, reproduction is essential for the continuation of a species. Glass frogs, as shown in Figure 1-4, lay many eggs in their lifetime. However, only a few of the frogs’ off- spring reach adulthood and successfully reproduce. During reproduction, organisms transmit hereditary informa- tion to their offspring. Hereditary information is encoded in a large molecule called deoxyribonucleic acid, or DNA. A short segment of DNA that contains the instructions for a single trait of an organism is called a gene. DNA is like a large library. It contains all the books—genes—that the cell will ever need for making all the struc- tures and chemicals necessary for life. Hereditary information is transferred to offspring during two kinds of reproduction. In sexual reproduction, hereditary information recombines from two organisms of the same species. The resulting offspring are similar but not identical to their parents. For example, a male frog’s sperm can fertilize a female’s egg and form a single fer- tilized egg cell. The fertilized egg then develops into a new frog. In asexual reproduction, hereditary information from different organisms is not combined; thus the original organism and the new organism are genetically the same. A bacterium, for example, reproduces asexually when it splits into two identical cells. Change Through Time Although individual organisms experience many changes during their lifetime, their basic genetic characteristics do not change. However, populations of living organisms evolve or change through time. The ability of populations of organisms to change over time is important for survival in a changing world. This factor is also impor- tant in explaining the diversity of life-forms we see on Earth today.
