In winter many dogs grow a thick coat of fur. this is an example of
a. adapting to change.
b. reproduction.
c. artificial selection.
d. genetic engineering.

The answer is letter A. 

Dogs grow a thick coat fur during winter because they are adapting to change. Adaptations are the result of evolution in different living organisms. This process occurs amazingly through gene mutation but it takes a very long period in time. Adaptation processes occur to help species survive and thrive in the ecological balance of life.

Structural adaptations are physical features of an organism that adapted through time. An example of this is the thick coat of fur that dogs naturally grow to protect themselves from the change of the weather.
