Answer:
The correct answer is c. cell fractionation
Explanation:
Cell fractionation is the technique which allows different cells part to be separated from each other on the basis of their density gradient by using a centrifuge.
In cell fractionation, first the cell wall and membrane of cells are broken by chemical, physical or mechanical method. Then the cell component can be separated by centrifuging them at different rpm.
Components that have higher density can be found in the bottom and the light density can be found on top of the tube. Therefore the correct answer is c. cell fractionation.
I think that the answer is true

The peripheral nervous system is categorised into two division: the somatic and autonomic.
The autonomic nervous system is the division which controls the autonomic function of the body whereas the somatic nervous system is the system which controls the voluntary functions of the body.
The somatic nerves transmit the signal from the skin, muscle and joints to the CNS and from CNS to the effector's muscles.
