Question

the fact that bees can detect ultraviolet rays humans cannot is due to the difference between the human and bee

o size differentiation.
o species wavelengths.
o absolute thresholds.
o visual spectrum.

Explanation:

The visual spectrum is the range of electromagnetic radiation that can be detected by the eye. Humans have a limited visual spectrum and cannot detect ultraviolet rays, while bees can because their visual spectrum includes ultraviolet wavelengths. Size differentiation is unrelated to detecting UV - rays. Species wavelengths is an incorrect term in this context. Absolute thresholds refer to the minimum intensity of a stimulus that can be detected, which is not the main reason here.

Answer:

D. visual spectrum
