Final answer:
Supination refers to a forearm position where the palm faces anteriorly. It is a biology topic that involves the rotation of the forearm bones to change the hand's position.
Step-by-step explanation:
In biology, the term supination refers to a forearm position in which the palm faces anteriorly or in a face-up position. This is the opposite of pronation, which is when the palm faces backward. Supination and pronation are movements of the forearm that involve rotation of the radius and ulna bones to change the hand's position.
