Rods respond to dim light, they're like our "night vision," when cones are required for color vision. Some animals have very few cones, which makes them only see certain colors. I believe you find out how many rods and cones an animal has by, well, disecting it.<BR/><BR/>Also, scientists give out certain tests to see how animals respond to colors. You know how you teach a dog to do tricks? Well, scientist teach animls to respond to those colors. I had helped a friend with an essay about it before.<BR/><BR/>Hope it helpes.Rainyhttps://www.blogger.com/profile/13419795585188793178noreply@blogger.com
