Body maintain Homeostasis by Negative Feedback mechanism. Because the stimuli causing the disturbance in the Homeostasis of the body is to be counteracted by a mechanism.

What is homeostasis?</h3>
The Homeostasis of the body is defined as the regulation of the internal environment of the body when there is a change.
In Positive feedback mechanism, it increases the response of the stimuli In temperature regulation, the stimuli are hot and cold.
Both are controlled by a opposing negative feedback mechansim that is when the body temeprature increases it is decreased to normal by a negative feedback mechanism , likely when the body temeprature is decreased(cold) , the body will increase the Body temeprature to normal By a Negative feedback mechanism that is exactly opposite(opposing) to the Former Negative feedback mechanism pathway.
In termparature regulation when body temperature raises ----->detected by nerve endings in the skin--Hypothalamus -----> signal to blood vessel for dilation activation of the sweat gland-the tempertaure is maintained to normal. -> signal send to the>heat is lossed and when body temperature decreases -----> detected by nerve endings in the skin------> signal send to the hypothalamus -----> signal to blood vessel for constriction inhibition of secretion from sweat gland, shivering ---->heat is generated -->normal.

Answer:
b. viruses do not undergo mitosis
Explanation:
One characteristics of non-living things is their ability to reproduce. Viruses on their own lack this ability to reproduce their kind. Mitosis is a form of reproduction where one cell divides to form two daughter cells. Viruses do not undergo mitosis.
Viruses are just an assembly of biochemical particles that need to gain entrance into a living cell to be able to multiply.
