______ usually do not exhibit the property of adaptation.

○ phasic receptors
○ photoreceptors
○ tonic receptors
○ sensory receptors

Explanation:

To solve this, we analyze each option:

• Phasic receptors adapt quickly (exhibit adaptation).
• Photoreceptors (for light) can adapt, but tonic receptors are known to have slow or no adaptation.
• Tonic receptors, like those for pain, maintain firing to a stimulus and usually do not exhibit adaptation.
• Sensory receptors is a broad term; many do adapt. So the correct one is Tonic receptors.

Answer:

C. Tonic receptors
