A population of salamanders includes both green-spotted and white individuals. The salamanders live in an area with heavy plant growth. What is the BEST prediction for how this population could change over time? a. The white salamanders will decrease because this type will not develop lungs. b. The white salamanders will increase becasue they are more likely to find food. c. The green-spotted salamander population will decrease because this type is more likely to develop disease. d. The green-spotted salamander population will increase because this type is less likely to be seen and eaten by predators. 21.

Which population of organisms would be in greatest danger of becoming extinct? a. A population with few variations living in a stable environment. b. A population with few variations living in an unstable environment. c. A population with many variations living in a stable environment. d. A population with many variations living in an unstable environment. 23. The graph above shows the variation in average beak size in a group of finches in the Galapagos Islands over time. These finches eat mostly seeds. Use the graph to answer the question that follows. Beak size in these finches is correlated to the size of seeds they can eat. What can be inferred from the graph? a. In wet years, the finches that survive are those that have larger beaks and can therefore eat larger seeds b. In all years, the finches that survive are those that have larger beaks and can therefore eat larger seeds c. In dry years, the finches that survive are those that have larger beaks and can therefore eat larger seeds
d. In all years, the finches that survive are those that have smaller beaks and can therefore eat smaller seeds 24. The diagram above shows possible evolutionary relationships between some organisms. What does the diagram imply about warbler finches and armadillos? a. They are unrelated b. They are equally related to glyptodonts c. They share a common ancestor d. They did not evolve from older forms of life. 25. Refer to the figure above to help you answer the question. Tortoises that have shells with higher openings can eat taller plants. Others can only reach vegetation close to the ground. Judging from the differences in the tortoises shells, what kind of vegetation would you expect to find on the large and small islands? a. Both islands would have a dense ground cover of low growing plants. b. The large island is less grassy, and plants grow with their leaves farther above ground. c. The small island is less grassy, and plants grow with their leaves farther above ground. d. The land is mostly dry on both islands with minimal shrub growth. 26.
