Question

which example best describes a reflex action? a. eating food when hungry b. bending down to lift a heavy object c. coughing when the throat is irritated d. going for a walk outside

Explanation:

A reflex is an involuntary and nearly instantaneous movement in response to a stimulus. Coughing when the throat is irritated is an involuntary action triggered by the body's defense - mechanism to clear the irritant from the respiratory tract. Eating when hungry is a voluntary action based on a physiological need but not a reflex. Bending down to lift a heavy object is a voluntary muscle - controlled action. Going for a walk outside is also a voluntary activity.

Answer:

C. coughing when the throat is irritated
