Bob put a frozen fish on the stage of a dissecting scope because he wanted to observe the cells in the fish’s eye. bob saw nothing. why?

His process is wrong.

Explanation:

Bob must take the eye out of the fish. Then he must cut the eye. After he cuts the eye he needs to take a thin layer of the eye and put it on the glass. A microscope needs light to shine through the specimen. All Bob would see when he put the fish on there would be black. The thick amount of mass is blocking the light.

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.
