Standard 5 Review- Chapter 7

Over time, animals may change behavior or physical appearance in response to changes in the environment. What is this called?

• adaptation

• genetic variation

• genetic change

• resistance

What is the process by which organisms that are better adapted to their environment survive and reproduce more successfully than less well-adapted organisms do?

• species separation

• genetic resistance

• genetic change

• natural selection

Many insects can adapt very quickly to insecticides because

• the insects form separate species.

• the insects' generation time is short.

• the insects have rigid exoskeletons.

• the insects' genetic structure is stable.

What evidence of natural selection is available today that was not available to Darwin?

• Organisms inherit traits.

• Differences in genes create variation.

• Humans can breed organisms for specific traits.

• There is great variation among organisms.

The process by which populations slowly change over time is called

• selective breeding.

• adaptation.

• speciation.

• evolution.

What process often begins by a portion of a population becoming physically or geographically separated?

• speciation

• selective breeding

• genetic change

• resistance

A characteristic that can be passed from parent to offspring through genes is called a

• resistance.

• sediment

• genetic change

• trait

What process would farmers use to produce vegetables that will grow in a specific climate?

• natural selection

• evolution

• selective breeding

• genetic variation

When certain genes make organisms more likely to survive and reproduce, which process can occur?

• adaptation

• selection

• selected breeding

• isolation

Scientists compare organisms' DNA to support the theory that all species share a common

• separation.

• ancestor.

• population.

• environment.
