5. if you touch something hot, what does your nervous system do?\nit cools the object down\nit makes your skin tougher\nit sends a message to the brain and tells your hand to move away\nit turns off your sense of touch
Answer
Brief Explanations:
The nervous system's role when touching something hot involves sensory neurons detecting the heat, sending a signal to the brain (central nervous system), which then sends a motor signal to move the hand away. The first option is incorrect as the nervous system doesn't cool objects. The second is wrong because skin toughness isn't related to this reflex. The fourth is incorrect as the sense of touch isn't turned off. Only the third option describes the correct reflex arc process.
