Which is an example of how humans maintain homeostasis in bad environmental conditions?
A
sweating in the heat
B
shivering in the heat
C
digesting amino acids
D
regulating glucose levels
Explanation: 

Detailed explanation-1: -Blood flow to your skin increases to speed up heat loss into your surroundings, and you might also start sweating so the evaporation of sweat from your skin can help you cool off. Heavy breathing can also increase heat loss.

Detailed explanation-2: -Whether you’re lying in the summer sun or playing in the winter snow, your body temperature only changes by a degree or two. That’s an example of homeostasis being maintained. When you get shivery in the cold, or sweat in the summer, that’s your body trying to maintain homeostasis.

Detailed explanation-3: -Sweating is an example of homeostasis as it helps regulate our body temperature. When our core temperature rises, we start to sweat. The evaporation of this sweat cools the body down, thereby lowering the elevated temperature.

Detailed explanation-4: -Body temperature control in humans is one of the most familiar examples of homeostasis. Normal body temperature hovers around 37 °C (98.6 °F), but a number of factors can affect this value, including exposure to the elements, hormones, metabolic rate, and disease, leading to excessively high or low body temperatures.

Detailed explanation-5: -Sweating that happens through either type of sweat gland serves a purpose. It maintains homeostasis, a stable equilibrium, of the skin and regulates body temperature. When our core temperature gets high enough through physical activity or high temperatures, sweating kicks off and cools you down while it evaporates.
