1 - Upside down. This is because vision originally sees upside down and as it is transferred, it is set right side up. I'm not sure if there's another blank for that, so I won't answer it as I cannot see the image.
2 - Rods and Cones.
3 - Retina. Draw an image of the general eye for this but include the rods and cones.
4 - Rods allow us to see black and white while cones allow us to see color. One way to remember this is that the beginning of both color and cone's start with the letters "co."
Hope this helps!
