Homework Answers
25 D choroid
it is vascular layer containing capillary network to provide oxygen to outer làyer of retina.
26. A Neural tunic
It is Retina that has rod cells which are more sensitive than cone cells to light.
27 C retinal ganglion cell
Retinal ganglion cell shoot action potential.

Questions 1 pts Humans and many other diurnal animals have three types of cones - one stimulated maximally by blue light, a second maximally stimulated by green light, and a third stimulated maximally by red light. How can human beings see colors such as orange, yellow and purple? When red cones are stimulated, they inhibit blue and green cones. When blue cones are stimulated, they inhibit only green cones. Green cones when stimulated, do not inhibit other cones, but do...
