Which demonstrates how genetic variation may result from a change in the environment where an animal lives?

• A salmon swims faster as it enters colder waters.

• A snake increases its body temperature because it moves on top of a rock in direct sunlight.

• A beetle stands out to predators because it moves among plants that have colors different than its own.
