Answer:
WATER REABSORPTION IN THE COLLECTING TUBULE OF TE KIDNEY
Explanation:
Antidiuretic hormone synthesized by the neurons in the hypothalamus and the posterior pituitary allows for the reabsorption of water from the collecting ducts of the kidneys back into the circulation.
This therefore reduces the amount of water in the urine causing the formation of concentrated urine and reduced volume of urine.
It causes the increased reabsorption of sodium in the ascending loop of Henle adding to the counter-current mechanism which aids the further reabsorption of water from the distal tubules and collecting ducts.
It also allows the constriction of arteries thereby reducing arterial blood pressure.
Some scientists hypothesize that the eukaryotic cells are really the result of symbiotic processes!
Specifically, the internal organs of the cells could be a remnant of a symbiotic relationship in which one cell lived inside of another cell. These two cells then both split upon reproduction and eventually the cell inside was reduced to an organelle.
But according to this theory, it is very likely that the prokaryotic cells engaged in a number of symbiotic relationship, and that this actually lead to the emergence of eukaryotic cells!

The answer is approximately 30%. Groundwater also comprises 1.7
percent of all of Earth's water. There is about 5,614,000 cubic miles (mi3), or
23,400,000 cubic kilometers (km3), of groundwater on Earth. About 54 percent is
saline (occurring in aquifers below the
oceans), with the remaining 2,526,000 mi3 (10,530,000 km3) , about 46 percent,
being freshwater.
Answer:
A. An energy storage molecule that cells use as energy 'currency'
Explanation:
Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.
