Question

Explanation:

The desert tortoise digs a burrow to stay cool in response to the extreme heat (a stimulus from the environment). "Response" refers to how organisms react to environmental stimuli. "Cellular organization" is about cell structure, "growth and development" is about changes over time, and "metabolism" is about energy processes—none match as well as "response" here.

Answer:

response (the option labeled "response")
