What do glycolysis, the citric acid cycle, and the electron transport chain have in common?
a) the production of atp
b)the process of trapping solar energy
c)occurrence of each within mitochondria
d)the process of breaking down sugar molecules

The factor hat glycolysis, the citric acid cycle, and the electron transport chain have in common is:

A) the production of ATP

Explanation:

The reasons behind the answer are:

Glycolysis unlike the citric acid cycle and the electron transport chain occurs outside the mitochondria.

All of them are procedures carried on to achieve cellular respiration however not all of them are involved in trapping solar energy. Also, they don't break sugar molecules in the same way. So, the only correct fact here is that all of them produce ATP even when they do it by different processes and different places.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
