Question

which sense is primarily responsible for detecting chemical stimuli in the environment?
taste and smell
touch
vision

Explanation:

Taste (gustation) and smell (olfaction) are chemoreceptive senses. Taste receptors detect chemical substances in food and liquids, while smell receptors detect airborne chemical molecules. Touch detects mechanical stimuli (pressure, vibration etc.), vision detects light (electromagnetic radiation), and hearing detects sound (mechanical vibrations in air).

Taste and smell
