Answer:
As proteins vary widely in structures than that of nucleic acid there will be greater structural and functional diversity of proteins than nucleic acid.
Explanation:
Proteins are the macromolecules which have more structural diversity than any other macromolecules such as carbohydrate,lipid,nucleic acid.
The are 4 types of protein structure primary structure,secondary structure,tertiary structure and Quaternary structure.Due the existence of many types of structure various protein exhibit various functions.
On the other hand nucleic acid such as DNA has widely accepted secondary structure discovered by watson and crick.As a result there is no such structural diversity exist in nucleic acid.
Metals don't form covalent bonds because of the low ionization energes of the metal atoms. It is easier for them to release electrons rather than sharing it. But this is not always the case, there are some metals that can form covalent bonds.

Answer:
The correct option is A
Explanation:
Water from a river is used for many activities in a community.

Rivers are not limited by what limits the influence of oceans such as taste (it's saltiness, which cannot be used in farming also) and wave current.
