1. Which model best illustrates the formation of blood cells? A- dissected pig B- plastic bone C- photograph of a bone D- computer-generated model

D- computer-generated model

Explanation:

Computer models are widely used to show real-life situations. Many biological, physical, chemical and engineering processes are easily simulated using a powerful computer system.

Therefore, the formation of blood cells can also be adequately simulated using a powerful computer system, hence the answer above.

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.
