How do skin receptors help in detecting a hot object?
Answer and explanation
Correct answer: They detect heat stimulus and start a nerve signal
The skin contains sensory receptors, including receptors that respond to temperature and pain. When a hand touches a hot object, these receptors are stimulated and convert the stimulus into nerve impulses. The impulses travel through sensory neurons to the central nervous system, where a suitable response can be organised. Thus option A is correct; the other options describe plant nutrition, hormonal regulation, or root growth.
