A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population.

A population is

• a group of similar species in different areas

• a group of the same species in the same geographic area.

• a group of several species in the same geographic area

• a group of several species along with their abiotic factors in a small area.

Over the years, white mice became extinct and darker mice survived. This is

• stabilizing selection

• directional selection

• disruptive selection

• due to exercise

61% accuracy: In rock pocket mice, for thousands of years the dominant fur color is lighter colored fur. Occasionally a mouse will be born with a change in the MC1R gene, which causes a darker fur color. This change is an example of a(n)...

Researchers studying medium ground finches on the island of Daphne Major in the Galapagos Islands collected the data below on the survival rates of finches with different sized beaks over a three-year period that included a drought.

Which statement about the finches in this environment is best supported by the data?

• Finches with large beaks are more fit for the environment than finches with small beaks are

• Finches with large beaks had more genes than the other finches did.

• Finches with small beaks reproduce more quickly than finches with large beaks.

• Finches with medium beaks had more mutations than the other finches did.

Reindeer from a rancher in Alaska escape from their pen during an enormous snow storm. After their escape, they mate with wild caribou that are migrating across the land. The offspring of these have traits for short legs and have tame behavior.

Insects become resistant to pesticides very quickly, sometime in one generation. If an insect is resistant to the chemical, most of the offspring will also be resistant. Considering that insect generations can be a matter of weeks, insects in an area can become immune to a chemical within months.
