THEY WILL NO LONGER BE ABLE TO PRODUCE ADEQUATE AMOUNT TO ATP.

Insects exposed to rotenone will die because they will not longer be able to produce adequate amount of ATP(Adenosine Triphosphate)

Explanation: Rotenone is a toxic substance that is crystalline in nature,it is gotten from roots of the derris plant,jicama vine plant and other similar/related plants,it is odourless and colorless and is used as an insecticide.

Rotenone affects insects by inhibiting the production of ATP and also inhibits the mitochondrial electron transfer system through the inhibition of the enzyme NADH ubiquitone reductase, which prevents the availability of oxygen for cellular respiration and also the most essential system that converts food to energy,attacking and impairing the function of cells if the central nervous system. Rotenone is both a contact and a systemic insecticide,it inhibits the transfer of electrons from Fe-S centers in complex I to ubiquinone in the electron transport chain. This prevents NADH (nicotinamide adenine dinucleotide) from being converted into usable cellular energy that is ATP and thus prevents the availability of oxygen for cellular respiration.

"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."
