The diagram shows changes within a herd of deer over many hundreds of years. Which statement best explains why some deer that went to the mountains survived and others did not?

The picture shows two mice called pocket mice. Pocket mice can be born with either light-colored fur or dark-colored fur. A group of pocket mice lives in a habitat where there is light sandy soil and dark lava rocks. Mice with light-colored fur blend in with the light sandy soil. Mice with dark-colored fur blend in with the dark lava rocks. Which habitat change would most likely benefit mice with dark-colored fur and not help mice with light-colored fur?

• Light sandy soil becomes very dry because of direct sunlight.

• Light sandy soil blows around in the wind and covers up dark lava rocks.

• Dark lava rocks break into small piece from weathering.

• Lava erupts from a volcano and then hardens into large areas of dark lava rocks.

Look at the picture above. Gazelle 2 has short legs instead of the normal long legs that Gazelle 1 has. Which best describes how having shorter legs will affect Gazelle 2?

• Shorter legs will have a positive effect because the gazelle will be able to run faster to escape from predators.

• Shorter legs will have a negative effect because the gazelle will not be able to run as fast and will be easier for predators to catch.

• Shorter legs will have a positive effect because the gazelle will be able to drink and store more water.

• Shorter legs will have a negative effect because the gazelle will not be able to drink enough water to survive.

Scientists discovered fossil evidence of mesohippus an ancestor of the modern horse. Mesohippus lived in North America about 40 million years ago. Mesohippus was about two feet tall, ran on hooves with three toes and had large, grinding teeth. It is believed that these early horses lived in the thick forests. What may have helped horses change over the last 40 million years?

• The coming and going of several ice ages.

• Being captured and used for work, pulling wagons and riding.

• A change in their food from trees to grass in the Great Plains

• An increase in weight.

• Fossils are not helpful in learning which organisms might be related.

• Organisms living today will probably be extinct in ten years.

• Organisms living today may be similar to organisms that lived long ago.

• Organisms living today have nothing in common with organisms that lived long ago.
