and for separating crude oil into different products such as petrol, diesel, and kerosene.

Explanation

Explanation

The Tyndall effect is the scattering of light by particles in a colloid or in very fine suspensions.

When light passes through a colloidal solution, the dispersed particles scatter the light in different directions, making the path of the light visible.

Explanation

Angiotensin III is part of the renin-angiotensin system, which regulates blood pressure and fluid balance.

The juxtaglomerular cells, located in the kidneys, release renin in response to a decrease in sodium chloride concentration in the distal tubules.

Renin then catalyzes the conversion of angiotensinogen to angiotensin I,

Which is further converted to angiotensin II, and subsequently to angiotensin III.

This cascade helps in regulating blood pressure and sodium balance.

Explanation

Charles' law states that, for a given mass of an ideal gas at constant pressure, the volume is directly proportional to its absolute temperature, assuming in a closed system.

The pascal is the SI derived unit of pressure

Explanation

f-subshell consists of 7 orbitals and each orbital can accommodate a maximum of 2 electrons

therefore f-subshell can accommodate a maximum of 14 electrons

Explanation

A thermos flask is used to maintain the temperature of liquids, keeping hot things hot and cold things cold for extended periods.

It achieves this by minimizing heat transfer through a combination of insulation and a vacuum. 

Explanation

Protozoa are often studied under parasitology because many are parasites causing diseases like malaria and amoebiasis.

Though protozoa are microorganisms, their parasitic nature makes them a key focus in parasitology.
