Which of the statement is correct ?
1 Polymerisation of many small molecules give rise to macromolecules such as proteins, nucleic acid and certain carbohydrates (polysaccharides).
2 Lipids are generally water insoluble.
3 Metabolite which is directly involved in physiological functions and help in growth, reproduction; and maturity is called secondary metabolite.

When triglycerides are solid at ordinary room temperature, they are called
1 oils
2 gases
3 fats
4 none of these
Explanation:
(c) Fats is a group of natural esters of glycerol along with various fatty acids. They are generally solid at ordinary room temperature. Fats occur naturally in food and play an important role in human nutrition. Fats store energy in the body, protect body tissues by insulating
them, cushion internal organs, and transport fat-soluble vitamins in the blood. Fats are soft, low-melting solids, with a density less than that of water.

Nucleotides are building blocks of nucleic acids. Each nucleotide is a composite molecule formed by
1 base-sugar-phosphate.
2 base-sugar-OH.
3 (base-sugar-phosphate)
4 sugar-phosphate.
Explanation:
(a) Nucleotides are the building blocks of nucleic acid. Each nucleotide consists of three parts: a sugar (ribose for RNA and deoxyribose for DNA), a phosphate, and a nitrogenous base.

A nucleoside differs from nucleotide is not having
1 sugar
2 phosphate
3 nitrogen
4 phosphate and sugar
Explanation:
(c) A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group. A nucleotide consists of a nitrogenous base, a sugar (ribose or deoxyribose) and one to three phosphate groups.
Nucleoside $=$ Sugar + Base
Nucleotide $=$ Sugar + Base + Phosphate
