__________________ are cells that of the epidermis that produce a substance that prevents water loss from the body surface
- A.
Keratinocytes
- B.
Melanocytes
- C.
Melanin
- D.
Keratin
Correct Answer
A. KeratinocytesExplanation
Keratinocytes are cells of the epidermis that produce a substance called keratin, which forms a protective barrier on the surface of the skin. This barrier helps to prevent water loss from the body surface, keeping the skin hydrated and preventing dehydration. Melanocytes, on the other hand, are responsible for producing melanin, the pigment that gives color to the skin, hair, and eyes. While melanin does provide some protection against UV radiation, it does not directly prevent water loss. Therefore, the correct answer is Keratinocytes.Rate this question:
