Raul has scraped his knee and noticed that after a week it had almost completely healed. Raul wondered how the skin was able to repair itself while looking exactly the same as his non-injured skin. In 3-5 sentences explain how mitosis plays a role in healing skin after injury and is able to maintain the look of the existing, non-injured skin.(4 points)

Mitosis plays a crucial role in healing skin after an injury. When the skin is wounded, the cells near the injury site receive signals to divide rapidly through mitosis. This division allows for new cells to be produced and fill in the wound. The new cells are identical to the existing skin cells because mitosis ensures that the newly formed cells have the same genetic information as the parent cells. Hence, mitosis allows for the repair of damaged tissue while maintaining the appearance of the non-injured skin.
