Vedclass · Answer

(A) Owls are nocturnal birds that possess a retina dominated by a large number of rod cells. Rod cells are photoreceptor cells in the retina that are highly sensitive to low levels of light,allowing for vision in dim light or night conditions. Conversely,cone cells are responsible for color vision and function best in bright light. Since the retina of an owl contains a very high density of rods and very few cones,they are adapted for excellent night vision but have poor color perception.
