Answer 1

The skin serves as a barrier, regulates temperature, and produces melanin and vitamin D.

Step-by-step explanation:

The skin has multiple functions. It serves as a barrier to prevent water loss and the entry of microorganisms. It also helps regulate body temperature and minimizes water loss. Additionally, the skin produces melanin, which gives color to the skin and protects against UV light. It also aids in the synthesis of vitamin D.
