In at least 5 sentences, describe the technique of x-ray crystallography.

The technique of X-ray crystallography is used for finding the atomic (gives energy to atoms and then to molecules) and molecular structure (The arrangement of chemical bonds between atoms in a molecule). The crystals will then cause the X-ray to beam a pattern onto a film structure. Then finally you're left with a diffraction pattern (passing through a narrow aperture (film) or across an edge, typically accompanied by interference between the wave forms produced).

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.
