What is an adaptation?

Back

An adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

What is mutation?

Back

Front

What does it mean for a trait to be advantageous?

Back

An advantageous trait is one that increases an organism's chances of survival and reproduction.

What is selective breeding?

Back

Selective breeding is the process of breeding plants and animals for specific traits.

Front

How do common traits arise in a population?

Back

Common traits arise because they are usually adaptive and help organisms survive and reproduce.

Front

What is the role of competition in natural selection?

Back

Competition for resources can lead to natural selection, as only the fittest organisms survive.

Front

What is the difference between structural and physiological adaptations?

Back

Structural adaptations are physical features of an organism, while physiological adaptations are internal processes that help an organism survive.

Front

What is the significance of genetic variation in a population?

Back

Genetic variation is important for a population's ability to adapt to changing environments.
