Question

mitosis is important because it allows
new cells to replace old damaged cells.
new cells to repair old damaged cells.
old cells to self - repair when they become damaged.
existing cells to take over the function of damaged cells.

Explanation:

Mitosis is the process of cell division that produces two identical daughter cells. Its role in tissue repair and growth involves generating new cells to replace old or damaged ones, not repairing old cells (cells don't "repair" in the sense of the options' wording) or having existing cells take over. So the correct option is the one about new cells replacing old damaged cells.

Answer:

A. new cells to replace old damaged cells
