Unit 12: Natural Selection and Adaptations Review

Front

What does 'survival of the fittest' refer to in the context of natural selection?

Back

Survival of organisms that are best adapted to their environment.

Front

What are heritable traits that aid survival and reproduction referred to as?

Back

Adaptations

Front

What is the primary function of physiological adaptations in organisms?

Back

To control how an organism's body functions internally.

Front

What is the term used to describe a slight difference in an inherited trait among individual members of a species?

Back

Variation

Front

Which of the following best describes the impact of variations on organisms?

Back

Variations can make some organisms better or worse suited to the environment.

Front

What is natural selection?

Back

The process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is an example of a behavioral adaptation?

Back

Migration of birds to warmer climates during winter.

Front

How do adaptations contribute to evolution?

Back

Adaptations enhance survival and reproduction, leading to changes in the traits of populations over generations.

Front

What is the difference between adaptation and acclimatization?

Back

Adaptation is a genetic change over generations, while acclimatization is a temporary change in an individual's response to environmental changes.

Front

What role do mutations play in natural selection?

Back

Mutations introduce new genetic variations that can be beneficial, harmful, or neutral, influencing an organism's fitness.
