Which of the following is not a characteristic of natural selection?A. Mutations appear randomlyB. Breeding pairs are chosen by humansC. More offspring are born than will survive to reproduceD. Organisms that are better adapted are more likely to survive2. The wings of a bird and the wings of an insect are A. Homologous structures B. Analogous structuresC. Vestigial structuresD. Similar structures3. Lamarck believed that _______________ traits are passed on, and Darwin believed that _________________ traits are passed onA. Acquired, inheritedB. Inherited, acquiredC. Acquired, artificial D. Artificial, acquired4. Which of the following statements best describes what will most likely occur to the moth populations in the image below???A. The light moths will be captured by predators more easily than the dark moths, and the population of light moths will rise.B. The dark moths will be captured by predators more easily than the light moths, and the dark moths will probably go extinct.C. The light moths will change their wing color to match that of the dark moths.D. The light moths will be captured by predators more easily than the dark moths, and the population of dark moths will rise.5.Which of the following statements is true about artificial selection?A. Breeders can control which animal’s mate.B. Breeders can control what mutations will appear in the offspring.C. Both A and B are true.D. Neither A nor B is true.6. Who created the binomial nomenclature system?A. Carl LinnaeusB. Charles Darwin C. Sir Charles LyellD. Jean-Baptiste Lamarck7. The pair of population graphs below display the results of two different five-year hunting cycles, one on light trees and one on dark trees. The population of light-colored moths is shown by the light gray dots, and the population of dark moths is shown by the dark gray dots. How do these results demonstrate natural selection???A. The moth populations shown here demonstrate random fluctuations over time that is not explained by tree color.B. On light trees, individual moths tried to become lighter in color to match the tree background. On dark trees, individual moths tried to become darker in color.C. The moths that were the same color as their background were more likely to survive and reproduce. Over time, the populations of these well-adapted moths increased.D. Small particles of tree bark became embedded in the moth’s wings, causing the moths to become darker on the dark trees and lighter on the light trees. These acquired traits were then passed down to the next generation of moths, causing the populations to change color over time.8. Suppose a certain species of insect lives in the lush green canopy of the rain forest. Some of the insects are bright green in color, and some are bright yellow. Assume there is a natural predator of the insect in the area. What do you expect to happen to the populations of the green and the yellow insects over time?A. The green insect population will increase and the yellow insect population will decreaseB. The green insect population will decrease and the yellow insect population will increaseC. Both insect populations will remain constant over time.D. Both insect populations will increase over time9. Natural selection can operate on predator populations as well as on prey. Suppose that over time trees became covered in lichen and the proportion of bright colored butterflies increased to nearly 100%. What is the most likely consequence for predator populations?A. Bird populations will decrease, at least for a while.B. Over time, birds with better eyesight will become more common.C. Birds may change hunting strategies or seek other sources of food.D. All of the above.10. A new kind of seed plant has been found on a remote island. This plant has larger, harder seeds than those found on the Galapagos Islands. Which of the following finch adaptations would be likely to arise on this new islandA. Longer legsB. Shorter legsC. Larger beak D. Smaller beak11. Which of the following statements best describes the response of finches to drought on the Galapagos Islands?A. During drought, individual finches saw that large, hard seeds were the only available food. To crack these harder seeds, individual finches grew their beaks larger, resulting in an increased average beak depth.B. During drought, finches struggled to open harder seeds. All the scraping and pecking wore down their beaks, resulting in a reduced average beak depth.C. During drought, only finches with larger-than-average beaks were able to crack the hard seeds that were available. These finches survived while smaller-beaked finches died, resulting in an increased average beak depth in the population.D. During drought, finches with smaller beaks (and smaller bodies) had an advantage. With reduced food supplies, larger finches (with larger beaks) were more likely to starve. The result was a decrease in average beak depth.12. What is a source of variation in organisms?A. Mutations and sexual reproductionB. Mutations and Asexual reproductionC. Asexual reproduction D. Sexual reproduction13. The older fossils had more ___________________ structures, and younger fossils had more _______________ structures.A. Complex, SimpleB. Simple, ComplexC. Analogous, homologousD. Homologous, analogous14. A student creates a dichotomous key to identify common household pets. What is wrong with this key???A. Hamsters have hairy bodiesB. Goldfish don't live in cagesC. A pet can have a hairy body and live in a cage, or can be hairless and not live in a cage.D. All of the above15. What two names are used in the binomial nomenclature system?Kingdom phylumGenus speciesSpecies genusOrder family16. What are the 6 kingdoms in the 6 kingdom classification system?Monera, Eubacteria, Protista, Fungi, Plantae, AnamaliaMonera, Archaebacteria, Protista, Fungi, Plantae, AnamaliaEubacteria, Archaebacteria, Monera, Fungi, Plantae, AnamaliaEubacteria, Archaebacteria, Protista, Fungi, Plantae, AnamaliaButterflies usually are identified by the colors and patterns on their wings. Butterflies have four wings: The two wings near the butterfly’s head are “forewings” while the wings near the butterfly’s tail are “hindwings.” You can use the following dichotomous key to identify four common butterfly species in North America.????Based on the key, what species of butterfly is shown below???A. Papilio polyxenesB. Danaus plexippusC. Colias philodiceD. Papilio glaucus18. Using your knowledge about DNA sequencing which of the following DNA sequences would be the closest relative to ATCGGCTAGGCCAATT?A. ATCGGCTAGGGCAATTB. ATCGGGTAGGCCAATTC. AGCTAGCTAAGCTAGGD. ATCGGCTAAAGCAATT19. What is the most accurate method for determining the age of fossils?Radioactive dating Radio wave dating Proteins DNA20. What determines traits in organisms?RNAGenesProteinsPolypeptide chains21. Which of the following is NOT a type of mutationsA. LossB. NeutralC. Duplication D. None of the aboveWritten Response: Answer each question to the best of your ability. Write your answer on this sheet underneath the question. How much each question is worth will be written beside each question. This section has a total of 17 marks22. Dolphin flippers contain a wrist and set of digit bones and associated muscles. Explain how this provides evidence that humans and dolphins share a common evolutionary origin. (1 mark)23. Provide an example of a vestigial structure. (1 mark)24. Explain the three conditions that are required for speciation to occur. (6 marks)25. A mutation occurred in a male chimpanzee where his tail did not fully develop. Females in this population found this absence of a tail to be attractive. This allowed this trait to become successful for reproduction. Explain how this mutation would become more frequent in the population after a few generations. Provide an explanation for this process, and use diagrams if needed. (3 marks)26. Describe a reproductive advantage and a survival advantage. Link these advantages to natural selection. (3 marks)27. A disease comes through and devastates a population of algae in a pond. Through the process of natural selection the best fit algae survived. Since algae reproduce asexually explain how the whole population didn’t die from the disease? (2 marks)28. Explain how sexual reproduction provides more variability in a population? (1 mark) ................
