a. When sensory information is detected by a sensory receptor, sensation has occurred. TRUE
For example, light that enters the eye causes chemical changes in cells that line the back of the eye. These cells relay messages, in the form of action potentials, to the central nervous system.

Absolute threshold refers to the minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time.
c. Sensory receptors are specialized neurons that respond to specific stimuli. TRUE
