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.
Answer:
mutation
Explanation:
As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation.
This is asexual reproduction and it shows offspring that have the same genes as the parent, since the genetic material was copied before the division.
