Siberian huskies have two layers of fur. the outside layer is rough and coarse, while the inner layer is very dense and thick. which theme of biology describes this phenomenon?

evolution explains unity and diversity through adaptation.

structure and function are related in biology.

organisms must maintain homeostasis.

all of the above are correct.

All of the above are correct.

Explanation:

The siberian huskies live in a cold environment. This is because of the fact that they are adapted to have a two layered fur so as to maintain their homeostasis and adapt to the cold environment. This is the basis for the evolution of these huskies. Thus it can be said that the structure and function in the biology are related. The two layered fur will help in retaining the heat.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
