Answer:
The answer is A
Step-by-step explanation:
Keratinocytes are the predominant cells found in the epidermis, which is the outermost layer of the skin. Their primary function is to produce and synthesize the protein keratin, a tough and fibrous structural protein. Keratin is a vital component of the epidermis, providing strength and resilience to the skin, hair, and nails. As keratinocytes mature and move towards the skin's surface, they undergo a process called keratinization, during which they fill with keratin and become tightly packed, forming a protective barrier that helps prevent water loss and protects the body from external damage, pathogens, and UV radiation. This process of keratinization is crucial for maintaining the skin's integrity and promoting its overall health and function.
