The production of insulin is a mechanism that regulates the human body's internal environment and aids in a:   the maintenance of homeostasis within the body system. b:   the production of carbon dioxide through cellular respiration. c:   the production of sugar molecules through photosynthesis. d:   the storage of genetic information within cells.

The correct answer is option A: "the maintenance of homeostasis within the body system".

Explanation:

The pancreas secretes insulin and glucagon, hormones that work together for the maintenance of homeostasis within the body system. When the blood sugar level is low, the pancreas secretes glucagon to raise them. When the blood sugar level is high, the pancreas secretes insulin to lower them.
