Question

what role do chemoreceptors play in taste and smell? detect pressure detect chemical molecules detect sound waves detect light waves

Explanation:

Chemoreceptors are specialized sensory receptors that respond to chemical stimuli. Taste (gustation) and smell (olfaction) rely on detecting chemical molecules from substances; pressure is detected by mechanoreceptors, sound waves by auditory receptors, and light waves by photoreceptors.

Answer:

Detect chemical molecules
