17. Template by Bill Arcuri, WCSD If the reproduction rate of the tree frog population remains constant over time. Question #9... A tree frog population lives in the canopy of a tropical rain forest.In this tree frog population, a mutation occurs that results in a new allele for skin coloration causing stripes on their legs. Which of the following factors has the greatest effect on whether leg stripes will become more common in the tree frog population? If enough food and water is available in the rain forest canopy for the tree frog population. If the new allele for stripes increases the survival of the tree frogs in their environment. If the new allele for stripes is dominant or recessive in the tree frog population. A CD B 50/50

18. Template by Bill Arcuri, WCSD In general, as emigration from an area increases, the population of the area decrease Question #10 : Which of the following best describes the influence of emigration on the size of a population? In general, as emigration from an area decreases, the population of the area decreases. In general, as emigration from an area decreases, the population of the area increases. In general, as emigration from an area increases, the population of the area increases. A CD B 50/50

20. Template by Bill Arcuri, WCSD They release nitrogen into the atmosphere when they replicate their DNA. Question #12... How do nitrogen-fixing bacteria help cycle nitrogen through ecosytems ? They convert ammonia from animal feces that plants can plants can uses They capture nitrogen from the atmosphere and convert it into forms that plants can use. They convert sunlight into chemical energy which is then stored in the nitrogen. A CD B 50/50

21. Template by Bill Arcuri, WCSD It will diverge into two species: one that eats small seeds and one that eats large seeds. Question #13... On a small isolated island, there is a single species of seed eating birds. Individual birds are able to eat seeds that are within 2mm (larger or smaller) of their beak depth. The distribution of individuals is shown. A long drought caused the plant species that produces seeds between 3-9 mm in size to go extinct. What does the theory of natural selection predict will happen to to the population of seed-eating birds over time? It will permanently shrink to approximately 25% of its current size. It will adapt and the birds that ate the medium sized seeds will learn toeat fish, insects, or other animals. It will go extinct because there aren’t enough seeds to support all individuals. A CD B 50/50

22. Template by Bill Arcuri, WCSD The neighborhood reached its carrying capacity for the pigeon population. Question #14... This graph shows a population of pigeons living in a neighborhood over a ten year period. Which of the following statements could account for the change in population seen between years 7 and 8? The migration rate of the pigeons decreased. The birth rate of the pigeons increased. The death rate of the pigeons exceeded the birth rate. A CD B 50/50

23. Template by Bill Arcuri, WCSD As population size approaches the carrying capacity, death rates begin to increase. Question #15... Which of the following best describes the relationship between carrying capacity and death rates? As population size approaches the carrying capacity, death rates approach zero. As population size approaches the carrying capacity, death rates begin to decrease. As population size approaches the carrying capacity, death rates remain unchanged, A CD B 50/50
