Answer:
C. Homeostasis
Explanation:
"Homeostasis" refers to the process of maintaining the body's equilibrium. The body tries to adjust to different stimuli in order to help it function in normal ranges. For example, when a person is exposed to a cold weather all of a sudden,<em> the person starts to shiver in order to maintain homeostasis</em>. <em>Shivering</em> is a contraction of the muscles that <em><u>allows the generation of heat</u></em>.
On the contrary, when a person is exposed to the sun during summer,<em> his body will start to sweat in order to maintain homeostasis</em>. <em>Sweating</em> allows the heat to dissipate from the body thereby lowering the body's temperature.

The menstrual cycle is practically controlled by a system of hormones that is necessary for reproduction, and when the hormone reaches a heightened level, something called estradiol is made, then the stimulation of the ovaries by a luteinizing hormone.
Once that hormone begins developing, the ovaries make an egg that quickly becomes an ovum. The ovary then releases one egg or two during ovulation. The endometrium (the part that sheds its own cells for the menstruation) peaks after ovulation and changes the lining of the uterus to prepare for the hectic process of pregnancy and child labor.
