H. The ermine's dark brown coat  in the summer changes to white is the winter.

Explanation:

If the ermine want to survive and not get attacked by predators, then they need to change the color of the coat from brown to white

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

there is none because earth is stationary and flat.
