The human body contains approximately 200 major cell types. they look and function differently from one another because: select one: a. each expresses a different set of genes. b. each expresses the same set of genes, but in different orders at different times. c. each has a slightly different genome. d. each has a slightly different genome and each expresses a different set of genes.

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.

the answer is "a.) well–developed vascular system."
