- Q1The results shown in the picture were obtained using a technique known as gel electrophoresis. This technique separates mixtures of DNA. In the picture nine different samples of DNA are compared. Gel electrophoresis can be used to —identify different blood typesidentify how closely two individuals are relateddetermine how effective certain medications aredetermine the differences in ages of a set of people120s
- Q2The diagram illustrates the activity of vesicles during a cellular process. Which statement best explains the function of the vesicles?delivering packaged materials to the golgi apparatus for protein synthesisextracting portions of the Golgi apparatus to be regenerated for growth within the cellTransporting packaged molecules from the Golgi apparatus to be released out of the cellExchanging genetic information between the Golgi apparatuses of separate cells120s
- Q3The graphs show the reaction rate for an enzyme across a range of temperatures and pH. Based on these data, this enzyme functions best at what temperature and pH?Temperature of 50°C and a pH of 10Temperature of 37°C and a pH of 6Temperature of 40°C and a pH of 8Temperature of 27°C and a pH of 4120s
- Q4The Indian leaf butterfly has traits that allow it to resemble a leaf. The bright colors of the monarch butterfly indicate that the butterfly tastes bad and can be poisonous. How does the appearance of these butterflies help them to survive?The Indian leaf butterfly is able to avoid predators while the monarch butterfly warns predators away.The Indian leaf butterfly frightens predators away while the monarch butterfly poisons predators before they can eat it.Both butterflies rely on camouflage to avoid predation.Both butterflies cooperate with one another to avoid predation.120s
- Q5The female reproductive and endocrine systems work interactively for which main purpose?To maintain homeostasis by removing waste products from the bodyTo release neurotransmitters during times of stressTo control hormone levels to prepare the body for pregnancyTo exchange gases to support cellular aerobic respiration120s
- Q6Scientists can determine relatedness among organisms by comparing partial amino acid sequences. The table shows four partial amino acid sequences from four organisms. Which organism is the LEAST related to the other three organisms?Organism 2Organism 4Organism 1Organism 3120s
- Q7In the 1880s, Louis Pasteur developed a method of weakening viruses. The weakened viruses could be injected into healthy individuals. How is this method effective in fighting viral diseases?The rate of genetic mutation in the host is decreased due to the introduction of weakened viruses.The weakened viruses attach to unaffected viruses in the host and interrupt the viral reproductive cycleThe immune system develops antibodies in response to the weakened viruses.Weakened viruses are unable to enter the host organism120s
- Q8In humans blood type is determined by the A, B, and O alleles. The A and B alleles are codominant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes?O onlyA or B onlyA, B, or O onlyA, B, AB, or O120s
- Q9Which of these best demonstrates mutualism between certain types of bacteria and humans?Intestinal bacteria obtain nutrients from the gut and produce vitamin K used by humans.Invasive bacteria at an area of injury produce toxins that damage healthy tissues of the human bodyBacteria in improperly prepared food is consumed by humans, causing food poisoning.Bacteria become resistant to antibacterial medication that humans use for treatment.120s
- Q10What is the role of mRNA in expressing specialized structures?Creating bonds to form biomoleculesProviding information to form proteinsMaking energy available for cellular activitiesProducing sugars that assist with replication120s
- Q11A student used a microscope to study four members of the phylum Ciliophora. Members of this phylum move when propelled by hundreds of tiny cilia. Although these organisms belong to the same phylum, they are classified as different —ordersfamilieskingdomsspecies120s
- Q12A mutation in which types of cells would only affect the organism and not future generations?sperm cell and egg cellsperm cell and lung cellegg cell and liver cellnerve cell and brain cell120s
- Q13In the mid-1980s an aggressive strain of algae known as Caulerpa was accidentally introduced into the Mediterranean Sea when a seaside aquarium cleaned out its tanks. The algae contains a toxin that prevents native herbivores from consuming it. Caulerpa quickly spread over the sea floor, crowding out many species including sponges, corals, sea fans, and lobsters. Which statement explains the most likely impact Caulerpa has had on the biodiversity in the Mediterranean Sea?Caulerpa interbred with native species with the same adaptations within the ecosystem.The presence of Caulerpa within an ecosystem is an indicator of the ecosystem’s health.Caulerpa became dominant within the ecosystem and reduced the biodiversity.The spread of Caulerpa improved the habitat for many species of sea grasses, and increased the biodiversity.120s
- Q14A sequence of a DNA template strand is shown. 3’ TCC AAT GGC TTA TTT GCA 5’ Which of these is the correct amino acid chain produced from the DNA template strand?Serine - Leucine - Proline - Asparagine - Lysine - ArginineTryptophan - Phenylalanine - Leucine - Glycine - Asparagine - PhenylalanineArginine - Leucine - Proline - Asparagine - Lysine - ArginineTryptophan - Phenylalanine - Leucine - Glycine - Asparagine - Serine120s
- Q15The diagrams show some of the levels of biological organization. In what order are the levels in the diagrams?Population--> community --> ecosystemEcosystem --> population --> communityOrganism --> community --> populationOrganism --> population --> community120s
