Question

the root word \dermis\ refers to the skin. which term refers to the outside layer of skin?

Explanation:

To determine the term for the outside layer of skin, we analyze the prefixes: "epi - " means "above" or "outer". "Epidermis" uses "epi - " + "dermis" (skin), so it refers to the outer skin layer. "Hypo - " means under, "sub - " means below, and "tachy - " relates to speed, so they don't fit.

A. epidermis
