Summarize the functions of the nervous system. A. The nervous system controls the digestive system by sending signals to the stomach, telling it to contract and digest food.
B. The nervous system controls the respiratory system by sending signals to the muscles, telling them to flex and move limbs.
C. The nervous system controls the muscular system by sending signals to the blood, telling it to move throughout the body.
D. The nervous system controls the circulatory system by sending signals to the lungs, telling them to expand and inhale oxygen.

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.

where is the scientific experiment?
