Final answer:
When a cell is damaged, it can either go into dormancy, undergo programmed cell death, or undergo unregulated cell division.
Step-by-step explanation:
When a cell is damaged, it can undergo different responses depending on the extent of the damage. One possibility is that the cell enters an irreversible state of dormancy, known as senescence. Another possibility is that the cell undergoes programmed cell death, also known as apoptosis. Lastly, the cell may undergo unregulated cell division, leading to the formation of tumors and cancers.
