Which demonstrates how genetic variation may result from a change in the environment where an animal lives?

• A salmon swims faster as it enters colder waters.

• A snake increases its body temperature because it moves on top of a rock in direct sunlight.

• A beetle stands out to predators because it moves among plants that have colors different than its own.

• An arctic fox changes its color over time because it migrates to an area with a different climate.

The population density of marine life is denser along the shorelines of the ocean than farther out in the deep waters of the ocean.  Which statement provides the BEST reason for this situation?

• Ocean currents prevent many smaller marine organisms from living in deep water.

• The shallow waters have fewer predators.

• Coastal waters are less polluted than the deeper waters of the ocean.

• There are more nutrients in shallow waters.

A scientist recognizes a white powder as sugar due to its white crystals and its sweet taste.  However, the scientist notices that the elements that make up the sugar - carbon, hydrogen, and oxygen - look nothing like sugar, nor are they sweet.  What is the best explanation for this?

• Sugar is a compound, and compounds usually have a different appear

• Sugar is an element, so its properties are unique.

• Sugar is a heterogeneous mixture, so its appearance is unique.

• Substances in nature change randomly and it is impossible to predict those changes.
