When the skin is scratched, it can break and create an open wound. This can allow bacteria to enter and cause infection, which may result in the development of an ulcer. Additionally, scratching can also irritate the skin and disrupt the natural healing process, further contributing to the formation of ulcers. Therefore, it is important to avoid scratching to prevent the occurrence of ulcers.

    Correct Answer
    scars
    Explanation
    Scars occur when ulcers have taken place and are in the process of healing. Ulcers are open sores that can develop on the skin or mucous membranes. When an ulcer forms, it damages the underlying tissue. As the body repairs this damage, it forms new collagen fibers, resulting in the formation of a scar. Scars can vary in appearance depending on factors such as the size and depth of the ulcer, as well as individual healing processes.
