Some arctic species like the arctic fox (pictured above) grow white fur only in winter. in summer, it is a brown color. what explanation best describes why animals like the arctic fox have this seasonal response in order to survive? a) the white fur keeps them warm b) the white fur them attract a mate c) the white fur them conserve energy d) the white fur them camouflage against predators

D) the white fur helps them camouflage against predators

Explanation:

Camouflage is a defense strategy in which living beings resemble the environment in which they live. In this case, individuals of a species may have a color, shape or texture similar to that of the environment and thus go unnoticed by their predator. However, the same mechanism can also be used by some predators to surprise their prey.

Camouflage is a result of natural selection and represents an adaptation that guarantees the survival of species in the environment.

An example of camouflage can be seen in changing the coat color of arctic foxes. In winter, the environment takes on a white color due to the snow. In order to hide from predators, the arctic foxes take on a white coat in order to be camouflaged with the landscape.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
