Piper accidentally cuts her finger while chopping vegetables. why does she feel pain?

She feels pain due to the presence of nociceptor in her body.

Nociceptor is a specialized sensory neuron capable of sensing noxious stimuli that is, the signals produced from damaged tissue or threat of damage.

They send these threat signals to the spinal cord and brain with the help of peripheral nervous system.

These signals are then processed in the thalamus of the brain.

The thalamus then forwards these signals to various parts of the brain such as somatosensory cortex (it causes physical sensation), front cortex (involve in thinking process), and limbic system (connected to emotions).

Together, they produced the sensation of pain.

It directs the attention towards the damaged body part and help in minimizing the damage or threat of damage.

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.
