The diagram below shows four types of finches labeled W, X, Y, and Z. The type of finch labeled W adapted different traits over a long period of time that resulted in the three different types of finches labeled X, Y, and Z. What is the most likely reason the finches labeled X, Y, and Z adapted different traits from the finch labeled W?

A species of moth in England has both a light-colored form and a dark-colored form. In the mid-1800s, the percentage of dark-colored moths increased in areas where black soot from factories covered the trees. The soot in these areas has decreased in more recent times as a result of pollution laws.

Which of the following statements describes what has most likely happened to the moth populations in these areas where pollution laws have been enforced?

A species of bird migrates from South America across the Atlantic Ocean to its summer breeding ground in northern Canada. The birds stop on the east coast of the United States to eat the eggs of horseshoe crabs. The migration route of these birds is shown on the map below. Which of the following changes would most threaten this species of bird with extinction?

The New England cottontail is the only rabbit native to New England. Current populations are small and isolated because of habitat loss. Scientists are concerned about the possible extinction of the New England cottontail.
Which of the following statements explains why having small and isolated populations puts these rabbits at risk for extinction?

Early explorers in the United States often observed huge flocks of passenger pigeons. In the 1800s, hunters began netting and shooting the birds in huge numbers to sell as food. In 1914, passenger pigeons were declared extinct when the last one died at the Cincinnati Zoo.
Which of the following best explains why passenger pigeons became extinct?

Researchers have observed that the biodiversity of some mountainside rain forests is greater than the biodiversity of some lowland rain forests. Which of the following statements best explains why a high degree of biodiversity is observed in some mountainside rain forests?

Northern foxes can have different fur colors.
The foxes hunt squirrels for food. Foxes that have fur the same color as their environment are better at getting closer to squirrels and catching them.
The diagram below shows a population of foxes that live in one area. At time 1, the population had the same number of brown and white foxes. At time 2, after many generations, there were many more brown foxes and fewer white foxes in the population.
