Most vertebrates have cone cells in their eyes, which distinguish colors in daylight. The rods are
more sensitive to light, but do not distinguish colors. If a mamal is nocturnal, it has likely
evolved to have...
As many cones as there are rods to capture the colors at dusk/dawn
Page 2 of 27
, An absence of cones since nocturnal mammals only need rods to see black/white at night
Fewer cones and a greater concentration of rods to collect the minimal light for night vision.
More cones than rods to enable them to see the muted colors at night. - Answer: Fewer cones
and a greater concentration of rods to collect the minimal light for night vision.

terms?
Diffusion
Active transport
Osmosis
Cellular respiration - Answer: Diffusion
