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.
1. N2 is exist as diatomic molecule in which two nitrogen atoms are attached to each other by triple bond this triple bond is due to p(pie)-p(pie) multiple bonding (sidewise overlapping) and such bonding is not possible in phosphorus due to it 's large size but possible in nitrogen due to it 's small size.. 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.
