Answer:
Moderate-intensity chemical.
Explanation:
Receptors may be defined as any cell, tissue or organ that has the ability to respond against the particular stimuli like light, smell and pressure. These receptors send information to the brain.
The olfactory receptor is involved in detecting the different type of smell. This will initiate the signaling process and generation of the action potential for the transformation of information. The moderate- intensity chemical can easily detect the change and induce the receptor action potential of the large amplitude.
Thus, the answer is moderate-intensity chemical.
