The regulation of temperature in the body is a good example of a C-feedback mechanism.
To understand why, let's break down the options:
A) A hormone-receptor complex: While hormones play a role in regulating various processes in the body, such as metabolism and growth, they are not directly involved in the regulation of temperature.
B) Prostaglandin: Prostaglandins are hormone-like substances that are involved in a wide range of physiological processes, but they are not specifically responsible for temperature regulation.
D) Exocrine gland: Exocrine glands are glands that secrete substances externally, such as sweat or saliva. While sweating is involved in cooling the body during exercise or in hot environments, it is only one aspect of temperature regulation and doesn't encompass the entire process.
C) Feedback mechanism: Temperature regulation in the body is primarily achieved through a feedback mechanism called thermoregulation. This process involves a constant monitoring of body temperature by specialized structures in the brain, such as the hypothalamus. When the body temperature deviates from its set point (normally around 37 degrees Celsius or 98.6 degrees Fahrenheit), the hypothalamus sends signals to produce appropriate responses. For example, if the body temperature rises, blood vessels in the skin dilate to promote heat loss through increased blood flow, and sweat glands produce sweat to cool the body down. On the other hand, if the body temperature drops, blood vessels constrict to reduce heat loss, and muscles may shiver to generate heat.
Therefore, the correct answer is C - feedback mechanism.
