The prefix EXO- conveys which meaning?

Explanation:
Exo- signals outward, outside, or away from the center. In medical terms you see it in exoskeleton (the outer skeleton), exogenous (originating outside the body), and exocrine (secretions released onto surfaces, outside the bloodstream). Because exo- specifies moving outward or being on the outside, it does not convey toward, into, or onto. Those directions are described by other prefixes or terms, so the meaning that fits exo- is away from.
