anyanavicka [17]

Answer: The answer is C!!! :D maintaining homeostasis by regulating the body's temp!

Explanation:

Shivering as a natural, involuntary response to generate heat is an example of  maintaining homeostasis by regulating body temperature.

Homeostasis refers to the maintenance of a relatively constant body environment. The normal range of operation of the body system is known as the setpoint.

When the setpoint temperature for some animals is breached, a negative feedback mechanism is used to return it to the setpoint. Shivering to generate heat is a response to a cold environment when the body's temperature is about to drop below the setpoint.

The oppositeis sweating. Sweating causes cooling and comes in response to when the setpoint temperature is exceeded.

Hopes this helps happy early Christmas!!!! :D

What part of the body is not working as it should when you have asthma
Nutka1998 [239]

Answer:

The Lungs

Explanation:

Asthma is a lung disease that affects your airways. With asthma, the lining of your airways is constantly hypersensitive, resulting in redness and swelling (inflammation). It's similar to how sunburned skin turns red, irritated, and sensitive. The airways become hypersensitive to things you are exposed to on a daily basis, or asthma "triggers." a trigger could be a common cold, stress, changes in the weather, or environmental factors like dust, chemicals, smoke, or pet dander.

Airway remodeling can occur as a result of poor asthma management. When asthma is untreated or poorly managed, it can lead to airway remodeling, which is a serious condition. The lungs become scarred, asthma medications become less effective, and less air can pass through your airways. It is not necessary to remodel the airways.

Hope this helps and if it does, don't be afraid to give my answer a "Thanks" and maybe a Brainliest if it's correct?
