Which adaptation would be most beneficial to mammals of both the taiga and marine aquatic biomes? A.
a thick layer of fat for insulation
B.
the ability to excrete excess salt through glands
C.
a layer of fur that reflects sunlight
D.
the ability to store food and water for hibernation

A. A thick layer of fat for insulation

Explanation:

Taiga is one of the world's coldest biomes. It includes the Canadian and Alaskan regions. Both taiga and marine mammals have adaptations that make it easier for them to survive in the harsh winter conditions. The mammals will be protected from the harsh winter environment and cold water by a thick layer of insulation. It will aid in the maintenance of homeostasis in mammals.
