"The desert tortoise digs a burrow and hides in it during the day to stay cool, because of the extreme heat above ground. Which characteristic of life does this behavior best illustrate?

A- response  B- metabolism  C- cellular organization  D- growth and development"

A- response  

Explanation:

An answer is the characteristic of life that this behavior illustrates. The term "response" is used to describe a behavior that a living being adopts in relation to a sternal stimulus, which can disturb or benefit the organism.

We can say that the question above is a good example of an "answer", because the turtle adopts the behavior of digging a hole and hiding in it during the day, because this allows the turtle to protect itself from the heat, which is an external stimulus that it bothers her.
