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.
The process that would stop if a chemical that interrupts cell division was added to a culture of human liver tissue is mitosis.
This is because cell division is mitosis and if the chemical stops cell division that means it stops mitosis.
