In the 1930's dr. robert goddard began his experimentation with space travel. these were the forerunners of the apollo spacecraft crew's setting foot on the moon in 1969. where did dr. goddard bring these experiments to life?

It was actually on March 14, 1926 in Auburn, Massachusetts that D. Robert Goddard launched his first liquid fueled rocket successfully.

Goddard’s rockets made little impression on government officials. Only through modest subsidies from the Smithsonian Institution and the Daniel Guggenheim Foundation, as well as the leaves of absence granted him by the Worcester Polytechnic Institute of Clark University, was Goddard able to sustain his lifetime of devoted research and testing.

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.
