Polar bears live in the Arctic. Ice in the Arctic is melting rapidly, reducing the range in which the polar bear can live. If polar bears do not have adaptations that allow them to survive these changes, what may happen to the polar bear?

• They may overpopulate.

• They may become extinct.

• They may change the environment.

• They may become another species.

The diagram below shows the changes over time in a population of mice in the wild after a population of hawks has moved into their environment. The white and dark mice differ only in color. Which statement is the most likely explanation for why the mouse population changed over time?

• The hawks eat more dark mice than white mice because the dark mice taste better.

• The white mice are able to reproduce more successfully than the dark mice do.

• The hawks eat more white mice than dark mice because they can see the white mice more easily.

• The hawks eat more dark mice than white mice, because they can see the dark mice more easily.

A certain reptile species is a herbivore and exists only on an isolated island. Which of the following would most likely result in the extinction of the reptile species over a period of twenty thousand years?

• The reptile species produces many offspring with many unique traits, and the vegetation remains constant.

• The reptile species produces few offspring with some unique traits, and the vegetation remains constant.

• The reptile species produces few offspring with no unique traits, and the vegetation changes quickly.

• The reptile species produces many offspring with some unique traits, and the vegetation changes slowly.
