How did genetic variation contribute to the change in the caterpillar population?

• The yellow caterpillars had more desirable traits.

• The brown caterpillars were better able to find food.

• The yellow caterpillars had fewer resources available.

• The brown caterpillars were better able to avoid predators.

Over time, the food supply for birds on an isolated island has changed. The supply of insects, small tender seeds, and vegetation has shrunk, whereas the supply of tough, large, hard seeds has remained unchanged. Over several generations, variations in genetic traits of birds' beaks have occurred. Which beak shape is the most likely result of this change to the environment?

• A

• B

• C

• D

In a certain area, mosquitoes that are resistant to the pesticide DDT now exist in greater numbers than 10 years ago. What is the best explanation for the increase in their numbers?

• Genetic differences permitted some mosquitoes to become immune to DDT.

• DDT was extremely harmful to the predators of mosquitoes.

• DDT killed only the weak in the previous generations of mosquitoes.

• Mosquito eggs were most likely to have been fertilized when exposed to DDT.

How has natural selection affected species of insect pests?

• Natural selection has not affected the number of species that are resistant to pesticides.

• Natural selection has gradually decreased the number of species that are resistant to pesticides.

• Natural selection has rapidly increased the number of species that are resistant to pesticides.

• Natural selection has only affected the numbers of species that were previously resistant to pesticides.
