Amplify Natural Selection Practice Test (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 adaptive trait?

Back

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

Front

What is a non-adaptive trait?

Back

A non-adaptive trait is a characteristic that does not provide any advantage in terms of survival or reproduction.

Front

How does environmental change influence evolution?

Back

Environmental changes can create new challenges or opportunities, leading to the evolution of species as they adapt to survive.

Front

What is the significance of genetic variation in a population?

Back

Genetic variation is crucial for natural selection, as it provides the raw material for evolution by allowing some individuals to be better suited to their environment.

Front

What role does competition play in natural selection?

Back

Competition for resources such as food, mates, and habitat can lead to natural selection, as only the fittest individuals survive and reproduce.

Front

How can a change in food sources affect a species?

Back

A change in food sources can lead to evolutionary changes in a species, as those that can adapt to the new food sources are more likely to survive.

Front

What is the difference between microevolution and macroevolution?

Back

Microevolution refers to small changes within a species, while macroevolution involves larger changes that can lead to the formation of new species.

Front

What is the concept of survival of the fittest?

Back

Survival of the fittest is a phrase that describes the process of natural selection, where the individuals best adapted to their environment are more likely to survive and reproduce.

Front

How do mutations contribute to evolution?

Back

Mutations introduce new genetic variations, which can lead to new traits that may be beneficial, neutral, or harmful to an organism's survival.
