Apoptosis can occur in a cell when the cell is . Group of answer choices no longer needed damaged infected by a virus all of the above (damaged, no longer needed, infected by a virus)

all of the above

Explanation:

The programmed cell death which is a part of normal growth and development of the cell is called apoptosis. Apoptosis occurs in multicellular organisms.  

By apoptosis, the body eliminated the old cell, unnecessary cells, damages cells, and the cells which are infected by viruses. Caspases are the enzymes that are activated during the time of apoptosis and mediates cell death.  

It kills the cell by cleaving some protein present in the cytoplasm and nucleus of the cell. By apoptosis, the body maintains the healthy cell numbers. So the right answer is all of the above.
