Question

1. what happens when you touch something hot?

your hand cools down the object
your lungs take a deep breath
nerves send a message to the brain, and the brain tells your muscles to pull away
your heart beats faster to cool your hand

Explanation:

When touching something hot, the nervous system (nerves) detects the heat, sends a signal to the brain. The brain then processes this and sends a response to muscles to pull the hand away. Other options are incorrect: hands don't cool hot objects quickly enough in this reflex, lungs breathing and heart rate increase aren't direct responses to touching hot.

Answer:

C. Nerves send a message to the brain, and the brain tells your muscles to pull away (assuming the third option is labeled C; if original labels are different, adjust identifier but keep the text. Since the options are: 1. Your hand cools down the object, 2. Your lungs take a deep breath, 3. Nerves send a message to the brain, and the brain tells your muscles to pull away, 4. Your heart beats faster to cool your hand, the correct one is the third option with text "Nerves send a message to the brain, and the brain tells your muscles to pull away")
