Answer

All answers are correct Explanation 1. Identify the primary functions of keratinocytes Keratinocytes are primarily responsible for producing keratin, a key protein that provides strength and protection to the skin. They also play a role in replacing older or dying cells. 2. Evaluate other options Keratinocytes do not produce collagen; this is typically done by fibroblasts. While they contribute to UV protection, their main function is not directly protecting basal cells from UV radiation.
