Unit 12: Natural Selection and Adaptations Review

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is an adaptation?

Back

An adaptation is a characteristic or trait that enhances an organism's ability to survive and reproduce in its environment.

Front

What is competition in the context of natural selection?

Back

Competition refers to the struggle between organisms for limited resources such as food, water, and shelter.

Front

Front

What is a behavioral adaptation?

Back

A behavioral adaptation is a change in behavior that helps an organism survive, such as migration or hibernation.

Front

What is a structural adaptation?

Back

A structural adaptation is a physical feature of an organism that enhances its survival, such as the long neck of a giraffe.

Front

How do environmental changes affect adaptations?

Back

Environmental changes can make certain adaptations beneficial or harmful, influencing survival and reproduction.

Front

What is mimicry in animals?

Back

Mimicry is when one species evolves to resemble another species for protection or other advantages.

Front

What is the role of genetic variation in natural selection?

Back

Genetic variation provides the raw material for natural selection, allowing populations to adapt to changing environments.

Front

What is selective breeding?

Back

Selective breeding is the process by which humans breed plants and animals for specific traits.
