Final answer:

The correct sequence of communication for feeling pain after stepping on a nail is stimulus, electrical impulse, receptor site, and neurotransmitter. The pain signal is transmitted via sensory neurons that generate an electrical impulse, which then is carried to the brain by neurotransmitters. Option E.

Step-by-step explanation:

When Mia stepped on a nail, the correct order of communication for her to feel the pain is as follows: Mia experiences a stimulus (the nail penetrating her skin), which activates sensory receptors.

These receptors then initiate an electrical impulse along a sensory nerve towards the spinal cord. When the impulse reaches the end of the nerve axon, it prompts the release of neurotransmitters.

These neurotransmitters travel across the synapse to bind with receptor sites on the dendrites of the next neuron. This binding allows the nerve impulse to continue and eventually reaches Mia's brain where the pain is perceived.

Therefore, the correct sequence from the options provided is (E) Stimulus-electrical impulse-receptor site-neurotransmitter.
