Question

sense mechanical change in surrounding tissues including touch, pressure, itching, and stretching
sense light
sense chemicals and chemical concentrations
mechanoreceptors chemoreceptors nociceptors thermoreceptors photoreceptors

Explanation:

Mechanoreceptors are sensory receptors that respond to mechanical stimuli such as touch, pressure, stretching, and vibration. Photoreceptors are specialized cells in the retina that detect light. Chemoreceptors detect chemical substances, either in the environment (taste, smell) or within the body (e.g., blood - gas levels).

Answer:

Sense mechanical change in surrounding tissues including touch, pressure, itching, and stretching - Mechanoreceptors.
Sense light - Photoreceptors.
Sense chemicals and chemical concentrations - Chemoreceptors.
