What is the main reason why penguins develop a thick layer of blubber?

It acts as a reserve store of energy.

It serves as insulation from the cold.

It provides cushioning on the hard ice.

It allows them to toboggan on their bellies.

all living organisms.
Which statement below best describes the relationship between natural selection and adaptation?

Natural selection and adaptation both describe how animals change.

Natural selection describes how organisms change and adaptation explains why.

Natural selection is the opposing force of adaptation in the environment.

Organisms undergo adaptive evolution as a response to natural selection.
A certain species of seed-eating bird lives on a remote island. Many young have recently been born with shorter beaks that can crush seeds more quickly. What factor is most likely responsible for this adaptation?

A decrease in temperature.

An increase in competition for food.

An increase in predators.
Organisms are constantly adapting so that they

are able to have a variety of food resources.

are better able to survive and reproduce in their environment.

can expand their population into new areas.

can push other competitive species out of their environment.
