Practice Test: Science Alive! Adaptations Lessons 3-5

Front

What was the main difference between the finches observed by Charles Darwin on the Galápagos Islands?

Back

Shape of their beaks

Front

What best describes an adaptation?

Back

A feature that helps an organism survive in its environment

Front

Which idea is most closely related to the theory of natural selection?

Back

Organisms with traits best suited to their environment are more likely to survive and reproduce

Front

Fossils provide evidence for evolution because they:

Back

Reveal changes in organisms over long periods of time

Front

In a population of insects, some are green and some are brown. If birds more easily see and eat the green insects, what will likely happen over time?

Back

The number of brown insects will increase

Front

What observation did Darwin make during his voyage that helped him develop his theory of natural selection?

Back

The finches on different Galapagos Islands had different beak shapes suited to their food sources.

Front

Evidence of Evolution: Select two different types of evidence scientists use to show that species have changed over time.

Back

Fossil records and comparative anatomy: Fossils show changes in species over time, and comparative anatomy reveals similarities among different species.

Front

These adaptations help the plants survive by:

Back

allowing them to live in their specific environments

Front

How does the development of thicker, whiter fur in rabbits over generations in a snowy environment support natural selection?

Back

The thicker, whiter fur helps rabbits blend into the snow and stay warm, increasing their chances of survival and reproduction.
