Retina receives lights and transfers it to the Optic Nerve
Good Afternoon,
I believe what you are speaking of may be the following. There is the equator is the center of the earth. Then, their is, on top of the equator, The Tropic of Cancer which passes through Cuba. On the bottom of the Equator, is the Tropic of Capricorn which passes through the Amazon Forest in South America. I hope that i have helped and good luck!
Thank you,

B. Decreasing the surface area of solid reactant;
Why? Collision theory suggests that the more opportunities for reactants to come into contact or "collide" with other reactants, the faster the reaction will take place. Hence, decreasing the surface area will decrease the probability of collisions between reactants thereby decreasing reaction rate.
