Ahigher concentration of molecules causes a fast chemical reaction. this is know as a) the law of mass action b)chemical equilibrium c) activation energy d) metabolism

A

Explanation:

A- The law of mass action is defined as "the principle that the rate of a chemical reaction is directly proportional to the concentrations of the reacting substances". This means that as the concentration of the substrates are increased, the rate of the reactions also increases.

Chemical equilibrium is where the products are being formed as fast as the are turned back into the substrate.

Activation energy is the energy needed to start a chemical reaction.

Metabolism is the rate at which chemicals (specifically in the body) are broken down.

"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."
