Explanation:
Detailed explanation-1: -If you touch something that is very hot, your hand moves away quickly before you even feel the pain. You don’t have to think about it because the response is a reflex that does not involve the brain. A reflex is a rapid, unlearned, involuntary (automatic) response to a stimulus (change in the environment).
Detailed explanation-2: -We move our hand away from a hot object. This is due to responsiveness to stimuli. When we touch a hot object the sense organs feel the temperature and the hand is withdrawn. The stimulus is carried to the brain by the sensory neuron while it is carried back to effector organs by motor neurons.
