Which of the following is a homostatic response in humans?
Answer Details
Shivering in a cold environment is a homostatic response in humans. Homostasis is the ability of the body to maintain a stable internal environment, despite external changes. Shivering is a mechanism that helps the body maintain its internal temperature in a cold environment by generating heat through muscle contractions. This is an example of a homostatic response, as it helps to maintain the body's internal temperature within a normal range. The other options are not examples of homostatic responses. Withdrawing the hand from a hot object is a reflex action to protect the body from injury. The mouth getting watery when food is sighted is a digestive response. Yawning due to tiredness is a physiological response, but not homostatic.
