Question

What is the function of keratin in the skin? A. kills bacteria B. absorbs ultraviolet radiation C. reduces desiccation D. carries wastes to be excreted

Answer 1

The correct answer is C. reduces desiccation.

Step-by-step explanation:

Keratin in the skin helps to reduce drying out by forming a waterproof barrier on the surface. It does not kill bacteria, absorb ultraviolet radiation, or carry wastes for excretion. Its main function is to protect the skin and underlying tissues from becoming dehydrated.
