Mitosis is the process by which cells divide to create new cells. When Raul scraped his knee, the body sent signals to nearby skin cells, prompting them to divide through mitosis and produce new cells to replace the damaged ones. This process helps the skin heal while maintaining the same structure and color as the uninjured skin, as the new cells are identical to the original ones. Additionally, the skin cells also produce proteins that keep the texture and appearance consistent, ensuring the repaired area looks just like the surrounding skin.
