Explanation
★Closing the eyelids at bright light is a reflex action, so the answer is reflex actions.
★A reflex action is an involuntary, automatic response to a stimulus.
★It occurs quickly through the spinal cord without conscious thought.
★The bright light acts as the stimulus and eyelid closing is the protective response.
★Instincts are inborn complex behaviour patterns, not simple automatic responses.
★Reflexes protect the body from harm before the brain fully processes the event.
