Question

b. how do you think your body maintains a stable internal temperature?

Explanation:

The question is about how the body maintains stable internal temperature, which relates to physiological mechanisms like thermoregulation. This falls under Biology (a subfield of Natural Science) as it involves studying body systems (e.g., nervous, circulatory, integumentary) and their roles in homeostasis. Key mechanisms include sweating (to cool) and shivering (to warm), regulated by the hypothalamus.

Answer:

The body maintains stable internal temperature (thermoregulation) via homeostasis. The hypothalamus acts as a thermostat: when too hot, blood vessels dilate (heat loss) and sweat glands secrete (evaporative cooling); when too cold, blood vessels constrict (heat retention) and muscles shiver (heat production). Hormonal and nervous systems coordinate these responses, with skin, muscles, and circulatory/endocrine systems involved.
