Night birds have ______ cones than rods in their eyes.
उत्तर
Night birds have less cones than rods in their eyes.
Explanation:
Night birds can see in the night, but not in the day. They have many rod cells and only a few cones on their retina. The owl has a large cornea and pupil, allowing more light into its eye. It also has a large number of rods and only a few cones on its retina. The day birds, on the other hand, have more cones and fewer rods.
