What is the term for changes in inherited characteristics that can cause a species to change over time?

Back

Evolution

Front

What is expected to happen to the population of brown and green frogs living in a brown, muddy lake over time?

Back

There will be more and more brown frogs.

Front

What do we call a characteristic that helps an organism survive in its environment, such as a giraffe's long neck?

Front

What are the slight differences within members of the same species, such as variations in feather color or beak length?

Back

Variations.

Front

What is the process by which organisms better adapted to their environment tend to survive and produce more offspring?

Back

Natural Selection.

Front

What is the term for the variety of different species in a particular habitat?

Back

Biodiversity.

Front

What is the role of mutations in evolution?

Back

Mutations introduce new genetic variations that can lead to adaptations.

Front

What is the difference between adaptation and acclimatization?

Back

Adaptation is a genetic change over generations, while acclimatization is a short-term physiological change in an individual.

Front

What is the significance of fossils in understanding evolution?

Back

Fossils provide evidence of past life forms and show how species have changed over time.
