it differs from perception in that it does not require receptor cells.
it is the process of transmitting neural energy into the external environment.
it is the process of organizing information so that it makes sense.
it is given meaning by the brain through perception.

Explanation:

For Question 3, the signal - detection theory posits that the detection of sensory stimuli depends on factors beyond the physical intensity of the stimulus and the observer's sensory abilities, such as the observer's motivation and expectations. For Question 4, sensation is the process of detecting stimuli by the sense organs, and it is given meaning by the brain through perception. Sensation requires receptor cells, it is not about transmitting neural energy into the external environment, and organizing information to make sense is more related to perception.

Answer:

Question 3: C. signal detection
Question 4: D. It is given meaning by the brain through perception.
