Rewrite the matching pairs as shown in the example.
Example: Fibrinogen-Clotting of blood

Column A	Column B
(1) Allele	(a) Control of automobile exhaust
(2) Leydig cells	(b) Tourniquet
(3) Utriculus	(c) Alternate forms of genes
(4) Snake bite	(d) Dynamic equilibrium
(5) Euro IV norm	(e) Testerone
	(g) Static equilibrium

Answer 1

Alleles are the alternative forms of a gene. The form of a gene which expresses itself is known as dominant and the other one is recessive.

Leydig cells secretes testosterone which regulates secondary sexual characters in male.

Mechanoreceptors in utriculus detect the horizontal or vertical movement of head (gravitational equilibrium) and thereby maintain the static balance of the body.

Tourniquet is the device which is used to stop the blood flow and is not recommended as first aid in case of snakebite.

Euro IV norms are concerned with regulation of emission of air pollutant from motor vehicles.
