Suppose that pollution caused snow in the arctic to quickly turn black, which happens sometimes in today’s urban areas. to adapt to this change over time, the arctic fox’s fur would
a) darken in the summer.
b) darken in the winter.
c) lighten in the summer.
d) lighten in the winter.

B) darken in the winter.

Explanation:

The arctic fox is a white-haired animal, common in the northern hemisphere.

Because of the color of its fur, this fox has a great facility in camouflaging itself in a snowy environment, managing to escape its predators who cannot perceive its presence.

However, if the snow is darkened by pollution, the Arctic spear will have to darken its fur in winter. This is because, if the fox continues with the white coat, it will not be able to camouflage and its presence in the environment will be very evident, which can attract predators.
