Raul has scraped his knee and noticed that after a week it had almost completely healed. Raul wandered 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 existing, non-injured skin. (4 points)
Mitosis is the process of cell division that allows for the replication and growth of new cells. When the body detects an injury, the cells at the site of the wound start to divide through mitosis to produce new cells. These new cells replace the damaged ones and help in the formation of new skin tissue. The replication of cells through mitosis ensures that the new cells have the same genetic information as the existing, non-injured skin cells, allowing for the maintenance of the same appearance.
