Question

select the correct answer. which action is a reflex action? a. asking for coffee in a cold climate b. blinking when light is flashed in the eyes c. drinking water when thirsty d. swallowing food e. taking an exam

Explanation:

A reflex action is an involuntary and nearly instantaneous movement in response to a stimulus. Blinking when light is flashed in the eyes is a classic example of a reflex. It is an automatic response that protects the eyes from potential harm without conscious thought. Asking for coffee (A) is a voluntary action based on preference. Drinking water when thirsty (C) is a response to a physiological need but involves some conscious decision - making. Swallowing food (D) has both voluntary (initial stage) and involuntary (later stages) components but is more complex than a simple reflex. Taking an exam (E) is a completely voluntary and conscious activity.

Answer:

B. blinking when light is flashed in the eyes
