what is centrifugation? explain.​

Answer 1

Answer:   :"""::CENTRIFUGATION """

Explanation:

Centrifugation is a method of separating molecules having different densities by spinning them in solution around an axis (in a centrifuge rotor) at high speed. ... Centrifugation is used to collect cells, to precipitate DNA, to purify virus particles, and to distinguish subtle differences in the conformation of molecules.

Answer 2

$\huge\red{\boxed{\sf Answer}}$

Centrifugation

Centrifugation is the process where a mixture is separated through spinning. Centrifugation uses a centrifuge.

Working of centrifuge

Centrifugation is sedimentation of particles under the influence of the centrifugal force and it is used for separation of superfine suspensions.The centrifuge holds the top of the tubes(in which a mixture is put), and the bottom is allowed to angle out. As it spins, the larger particles would get flung out further, and smaller particles would stay closer to the center.

Method of separating cream from milk

A separator is a centrifugal device that separates milk into cream and skimmed milk. Separation was commonly performed on farms in the past. Most farmers milked a few cows, usually by hand, and separated milk.

Separating cream from milk

A separator is a centrifugal device that separates milk into cream and skimmed milk. Separation was commonly performed on farms in the past. Most farmers milked a few cows, usually by hand, and separated milk.

Milk is a suspension of tiny droplets of oil (cream) in a watery liquid. The process of centrifugation is to separate cream from milk. The milk is put in a closed container in big centrifuge machine.When the centrifuge machine is switched on, the milk is rotated (or spun) at a very high speed container Due to this the milk separates into 'cream' and 'skimmed milk .The cream, being lighter, floats over the skimmed milk.It can then be removed. Thus, cream is separated from milk by centrifugation.
