The correct option is B. It regulates body temperature.
<h3>What is homeostasis?</h3>
In biology, homeostasis is the condition of steady internal, physical, and chemical requirements maintained by living systems.
- This is the requirement of optimal functioning for the organism and contains many variables, such as body temperature and fluid balance, being kept within certain pre-set limitations (homeostatic range).
- Other variables include the pH of extracellular fluid, the engagements of sodium, potassium, and calcium ions, as competently as the blood sugar level, and these need to be regulated despite changes in the atmosphere, diet, or level of activity. Each of these variables is controlled by one or better controllers or homeostatic mechanisms, which together maintain life.
- Homeostasis exist obtained about by a natural resistance to switch when already in the optimal conditions, and balance is maintained by many regulatory mechanisms.
- All homeostatic control mechanisms include at least three interdependent elements for the variable being regulated: a receptor, a control center, and an effector.

Answer:<em> The Miller-Urey experiment provided the first evidence that organic molecules needed for life could be formed from inorganic components. Some scientists support the RNA world hypothesis, which suggests that the first life was self-replicating RNA.</em>
Explanation:
Simple organic compounds might have come to early Earth on meteorites.
Indigestable food moves from the small intestine to the large intestine where water is absorbed back into the body. The waste is then passed through the rectum and excreted from the anus.
I would say the large intestine.
