Out of the following given choices;
A Bowman's capsules
B afferent and efferent arterioles
C nephrons
D collecting duct
E glomeruli
The answer is D. Also known as vasopressin (a stress hormone)
acts on the receptors of the collecting ducts of the nephron during water
stress to increase water reabsorption. The hormone stimulates water reabsorption by stimulating insertion of
"water channels" or aquaporins into the membranes of kidney tubules.

Answer:
The answer is letter a, chemical evolution.
Explanation:
Chemical Evolution <u>is one of the processes that helps explain the origin of life. It states that the first living cell on earth started from non-living matters that were not capable of reproducing.</u>
This <em>non-living matter </em>could be both <em>organic and inorganic molecules.</em> It is said that the structures of these molecules changed over time (example is protein breaking down when exposed to too much heat). When these systems become complex, they form new structures (this is known as repetitive reproduction). This then gives rise to bacteria.
Thus, this explains the answer.
