Answer 1

Answer:

eyes

cones helps to determine the colour

Answer 2

Answer:

Eyes

Explanation:

Cones: Sense bright light and sense color.

Rods: Sense dim light.

Basically, you know how when you turn the lights off after staring at an object emitting light, you cannot see anything.
This is because of the Cones which want no more bright light to enter our eyes, so they dim our vision.
Whilst, when you haven't stared at light and you're in the dark, you can see everything.

This is because of the Rods which want some bright light to enter our eyes thus trying their hardest to make as much light enter our eyes as its possible. This improves night-vision.

Hope this helped you understand :D
