c. the ratio between cGMP and cAMP.
d. the types of cone photoreceptors activated.
e..the number of photoreceptors activated.

e..the number of photoreceptors activated.--------------answer
A photoreceptor cell is a particular sort of cell found in the retina that is equipped for phototransduction. The immense organic significance of photoreceptors is that they change over light (noticeable electromagnetic radiation) into signs that can animate natural procedures. To be more particular, photoreceptor proteins in the phone assimilate photons, setting off an adjustment in the cell's film potential.
the Pathway of light goes in towards the retina (foremost to back) and the the pathway yield goes from the photoreceptors in the retina (back to and front):
photreceptors-> Bipolar cells - > gengilion cells - > axons of ganglion cells - > (foremost to back) optic nerve
