During the Industrial Revolution, factories would spew smog and soot into the air and release pollutants and chemicals directly into rivers and streams, resulting in increased air and water pollution. Which of the following genetic variations would explain why populations of peppered moths changed after the industrial revolution?

• A genetic variation in color of the moth created more black moths that could blend in better than the white moth, so this trait was passed on.

• A genetic variation in hibernation time allowed the black moth to hibernate longer than the white moth, so this trait was passed on.

• A genetic variation in resistance to pollution allowed the white moth to resist chemicals more than the black moth so this trait was passed on.

• A genetic variation in wing size caused the black moth to have larger wings than the white moth, so this trait was passed on.

Select any of the following forms of evidence that would support the idea that genetic variations in a population cause an increase in some individuals being able to survive and reproduce.

• A population of insects remains identical as their environment changes.

• The shapes of the finch beaks in environments were well-matched with the seeds available for one location, but not the seeds in other environments.

• Some catepillars are able to mimic deadly snakes, which often keep would-be predators away from them.

• Male peacocks with bright tail feathers tend to attract females more often during mating season.

Darwin noticed that different tortoise species lived on islands with different environments. He realized that the tortoises had traits that allowed them to live in their particular environments. Tortoises that ate plants near the ground had rounded shells and shorter necks. Tortoises on islands with tall shrubs had longer necks and shells that bent upward, allowing them to stretch their necks. Which of the following mathematical models would most accurately show predicted populations for both tortoises over on an island with mostly plants near the ground?
