Many types of stimuli cannot be sensed directly by humans because we lack sensory receptors to transduce the energy of these types of stimuli.

Question

Quizplus · Accepted Answer

Humans can only sense a limited range of stimuli because our sensory receptors are specifically adapted to transduce certain types of energy (like light, sound, and chemical substances) into neural signals. Stimuli outside these ranges, such as ultraviolet light or ultrasonic sounds, cannot be directly sensed because we lack the necessary receptors.
