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.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
