Figure 1 illustrates the change that occurred in the trait for spots in an insect population over 10 generations. The
frequency of the trait for spots in the insect population was studied for the 10 generations.
FIGURE 1
10. The best explanation for this change would be that over time
a. the presence of spots gives the insect an advantage in its environment.
b. the absence of spots gives the insect an advantage in its environment.
c. the absence of spots has no effect on the survival of the insect.
d. the presence of spots has no effect on the survival of the insect.
11. In any particular environment, variations among members of the same wild bird species may be the result of
a. asexual reproduction.
b. sexual reproduction.
c. selective breeding.
d. binary fission.
12. All of the following factors affect natural selection, except
a. overproduction.
b. competition.
c. variation.
d. Competence
13. Natural selection is a method by which genetic material is transferred to the next generation
a. through human control and manipulation.
b. through genetic engineering and gene therapy.
c. when organisms that are adapted to the environment survive and reproduce.
d. when all organisms in an environment survive and reproduce.
14. What is the set of DNA that controls a trait which an organism may have
a. Variation
b. Gene
c. Selective breeding
d. Natural selection
15. Jamie wants to sell seeds that make yellow pea pods. Green pods are dominant and yellow pea pods are
recessive. Which of the following methods would be the best way for Jamie to produce yellow pea pods to
sell?
a. Propagation by budding
b. Selective Breeding
c. Natural Selection
16. Using the information about green and yellow pea pods from question 6, which statement best describes
which type of pea pod plant would be most common if the plant reproduced without human intervention?
a. More plants would have yellow pods
b. More plants would have green pods
c. Half of the plants would have yellow, and half of the plants would have green

Brief Constructed Response
During the Ice Age (over 20,000 years ago), giant ground sloths were commonly found across North and South
America. It is believed they could stand onto their back legs to reach leaves in trees up to 25 feet high. About 15,000
years ago, the climate began to slowly warm.
21. Explain why the giant ground sloth is no longer found in North America. Use information we have learned about
evolution, especially the physical factors and biological factors which could have contributed to the extinction of this
species.
