loris [4]

The question is incomplete as it does not have the options which are:

- Yes, because people's eyes move during sleep, and this stimulates the rods and cones.

- No, because rods and cones only convert light energy into electrical signals.

- No, because rods and cones never produce electrical signals.

- Yes, because the rods and cones are reproducing images that are then sent to the brain.

Answer:

No, because rods and cones only convert light energy into electrical signals.

Explanation:

The rod and cone cells are the photoreceptor cells present on the retina of the eye which receives the physical stimulus in the form of light and then converts the light energy into the electrical energy which is sent to the brain.

When we dream, our remains closed and no light is able to enter the eye as a result of which the rods and cones do not send the signals to the brain.

Thus, the selected options are correct.
