Question

Which of the following is an example of maintaining homeostasis? Learning Jumping Shivering Smiling

Answer 1

Answer:

Option). shivering.

Explanation:

Homeostasis can be defined as maintaining the steady state of chemical and physical conditions by living organisms. Shivering is one way to achieve homeostasis as it maintains internal body temperature.

The average internal human body temperature is 98.6 F. A drop in body temperature is detected by nervous system that triggers muscle contraction to start shivering. Shivering increases body temperature by producing heat and restores homeostasis.

Thus, the correct answer is option). 'shivering.'

Answer 2

The answer is D, sweating.

Homeostasis is where the body uses some mechanisms to maintain a optimum condition for the body to function. These conditions may include body temperature, blood glucose level etc.

Sweating is a mechanism that can help maintain the body temperature. During hot conditions, the sweat glands under the skin surface may produce sweat, which is then released to the skin surface. When the sweat is on the skin surface, they evaporate. During evaporation, heat energy is brought away from the skin as the sweat molecules that have a higher kinetic energy (=temperature) escaped from the sweat drop. The average temperature of the sweat is reduced. Eventually, the temperature of the body is decreased and this help maintain the suitable temperature for the body to function.

Therefore, your answer is D, sweating.
