17. C. Here, Sensory adaptation explains the diminishing sensitivity to the stimulus.
18. C. This is because rods and cones are the primary retinal receptor cells which receive information about colour and lightness-darkness.
19. A. The wavelength of light which strikes the retina determines the perception of colours such as red for long wavelength, violet for short wavelengths etc.
20. D. The iris is the part which controls the size of the pupil by relaxation and contraction movements.
21. B. Light first enters the cornea. The cornea is a transparent layer which covers all the other structures.
22. C. The lens focuses light onto the retina by refraction of light.
23. B. Rods help in vision in dark conditions as they respond to low light levels.
24. D. Damage to the occipital lobe or the visual cortex is associated with the phenomenon of blindsight.
