A. Wind energy doesn't pollute the air.

Explanation:

Wind energy is a renewable source of energy due to abundance of wind in the atmosphere. The wind energy is harnessed by high speed wind currents used to run the wind turbine. The turbine convert the wind energy into electrical energy.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
