Question

order the statements below to describe the population before and after the environmenta change.

the population of mice is in an environment with many black rocks.

a sandstorm covers most of the populations environment with brown sand.

after many generations, most of the mice in the population have brown fur.

mice with brown fur are more likely to survive and reproduce than mice with black fur.

mice with brown fur are less likely to survive and reproduce than mice with black fur.

after many generations, most of the mice in the population have black fur.

Explanation:

First, the mice are in an environment with black rocks. So, mice with black fur are better camouflaged and more likely to survive and reproduce (mice with brown fur are less likely to survive and reproduce than mice with black fur). Then a sandstorm changes the environment to brown sand. Now, mice with brown fur are better camouflaged. So, mice with brown fur are more likely to survive and reproduce. After many generations, the trait that helps survival (brown fur now) becomes more common (most mice have brown fur).

Answer:

1. The population of mice is in an environment with many black rocks.
2. Mice with brown fur are less likely to survive and reproduce than mice with black fur.
3. After many generations, most of the mice in the population have black fur.
4. A sandstorm covers most of the population's environment with brown sand.
5. Mice with brown fur are more likely to survive and reproduce than mice with black fur.
6. After many generations, most of the mice in the population have brown fur.
