Answer:
For this receptor, the stimulus begins with an explosion of action potentials.
that would be the correct option.
Explanation:
A tonic receptor is one that is activated when the action potentials were maintained over time and during the signaling of the receptor.
Tone receptors require continuous stimulation over a period of time to trigger a response and deliver it to the central nervous system.
