Viruses have many things in common with living organisms, but they are not actually considered living. Why?.

-Viruses can't reproduce by themselves. They require a host animal to do so.

-Viruses are not made of cells

-They can't keep themselves in a stable state (regulate temperature)

-They don't grow

-They can't make their own energy

Hope this helps :)

because the light is a great source of energy for the plants to survive. (i hope this )

"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."
