Exp: B Hydrolysis of lipid can break down a fat or oil and release the triglyceral and fatty acids. An enzyme called lipase catalyses the hydrolysis of the fats and oils. It also known as lipolysis. Fats \(+\mathrm{H}_{2} \mathrm{O} \xrightarrow{\text { lipase }}\) Glycerol + Fatty acids

Chemically wax is :
1 a protein
2 a lipid
3 a carbohydrate
4 an amino acid
Explanation:
Exp: B Naturally waxes are present as coating on leaves and stems and prevents the plant from losing excessive amount of water. It is a simple lipid which is an ester of a long-chain alcohol and a fatty acid. Alcohol may contain from 12-32 carbon atoms.

Paraffin wax is :
1 ester
2 acid
3 monohydric alcohol
4 cholesterol
Explanation:
Exp: A Paraffin wax is classified as a petroleum wax. It comes from petroleum, coal and oil shale. The esters of long-chain (about 14-C to 36-C atoms) saturated and unsaturated fatty acids with long-chain alcohols (16-C to \(30-\mathrm{C}\) atoms) are known as waxes. It means, chemically the waxes are esters

In DNA molecule, the number of hydrogen bonds between adenine and thymine are:
1 two
2 three
3 four
4 eight
Explanation:
Exp: A In DNA molecule, Adnenine (A) and Thymine \((\mathrm{T})\) together form a double hydrogen bond \((\mathrm{A}=\mathrm{T})\) while Cytosine and Guanine form a triple Hydrogen Bond \((\mathrm{C} \equiv \mathrm{G})\). Hydrogen bonds are formed between complementary nitrogenous bases on the interior of DNA.
