Detailed explanation-1: -Answer and Explanation: Homeostasis consists of the regulation of all of the options except for body weight, which depends on caloric consumption.

Detailed explanation-2: -Homeostasis is the regulation of the internal conditions within cells and whole organisms such as temperature, water, and sugar levels. This keeps cells and organisms functioning at optimal levels even when challenged by internal and external changes.

Detailed explanation-3: -Homeostatic mechanisms control feeding in response to general energy deficit or other types of metabolic need, whereas non-homeostatic mechanisms include learning, memory, and cognitive processes that can affect feeding based on previous learned experiences and hedonic aspects of food.

Detailed explanation-4: -All homeostatic control mechanisms have at least three interdependent components for the variable being regulated: a receptor, a control center, and an effector.

Detailed explanation-5: -Failure of Homeostasis Sometimes, however, the mechanisms fail. When they do, cells may not get everything they need, or toxic wastes may accumulate in the body. If homeostasis is not restored, the imbalance may lead to disease or even death.
