Which statement is the best explanation why animals hibernate?
They are cold.
To hide from predators
To conserve energy and survive when food is not available.
To relax
Seeds are the major source of food for finches. A drought increases the number of
large seeds and decreases the number of small seeds available to the finches. During
periods of drought only the finches with large beaks will be able to crack and eat the
large seeds. How will this affect the finch population?
The populations of all the finches will decrease
Finches with large beaks will be able to eat and survive and thus produce offspring with larger beaks
Finches with small beaks will be able to eat and survive and thus produce offspring with smaller beaks
D
Finches with smaller beaks will find ways to eat the larger seeds and thus survive to produce more offspring with smaller beaks.
A population of termites initially consists of darkly colored and brightly colored members.
After several generations, the termite population consists almost entirely of darkly colored members because the brightly colored termites are easier for a predatory species of insectivores to locate. This situation is an
example of

natural selection.
artificial selection.
adaptation

Natural selection is responsible for changes in genetic traits that occur over several generations. An example can be seen in a type of bird called a finch that has the scientific name Geospiza fortis. This graph shows how the size of this bird increased over several generations. During the years shown on this graph, a drought occurred on the tropical island where these birds live. As a result, the seeds that these birds eat became harder and larger. What happened to the bird population in response to this change in the environment.
The birds became extinct because they could not break open the large, hard seed coverings.
The birds became larger, so they retained body heat better and didn’t need as much food.
The beaks of the birds became long and thin so they could feed on insects rather than seeds.
The birds became larger, because the bigger birds had bigger beaks to eat the bigger seeds.
