Select the statement that best describes homeostasis:

A. internal mechanisms that decrease physiological variables.
B. prevention of changes from happening within the human body.
C. maintenance of a dynamic state of equilibrium within the human body.
D. spontaneous induction of changes to alter the internal state of the body.

C. maintenance of a dynamic state of equilibrium within the human body.

Explanation:

Homeostasis is the maintenance of body equilibrium. This is done by constantly adjusting to the changes in the body system. There is a set point in the body homoestasis ensure that irrespective of the changes in the body system it goes back to the set point.

The changes in the environment is sensed by the receptor which then send signals to the brain from where the receptors picks it up and respond. The respond could either contrast or relaxes in its response.

Homoestasis is maintained by negative feed back and it is controller in the nervous system in mammals.

C. maintenance of a dynamic state of equilibrium within the human body.

Explanation:

Homeostasis is a phenomenon which organisms undergo in order to maintain a dynamic state of equilibrium. Homeostasis helps mainly in the balance of the body’s temperature and fluid.

When organisms are exposed to external conditions such as heat, cold etc , the body tries to balance the internal body system for its optimal functioning and survival. Excess heat can cause dehydration and death but the body uses the sweating mechanism in which the skin excretes little water and then it cools off on the skin thereby reducing the heat content.

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction

the answer is :
