ADH conserves body water by decreasing urine production. ADH causes the kidneys to return more water to the blood and this has the effect of decreasing urine volume.ts gotta be A because ADH helps the kidney conserve the water but not salt.

Nucleic acids are polymers of individual nucleotide monomers. Each nucleotide is composed of three parts: a 5-carbon sugar, a phosphate group, and a nitrogenous base. Only two 5-carbon sugars are found in nature: ribose and deoxyribose.
In N2 the two nitrogen atoms form a triple bond. This triple bond has very high bond strength, which is very difficult to break. It is because of nitrogen's small size p pi-p pi bond with itself.. Nitrogen does not catenate like carbon or phosphorous here and hence forms triple bond with another N-atom, which is a very very strong bond and satisfies its octet thus it has no requirement to catenate and form long chains, and exists as an almost inert gas in atmosphere.
