The human body can be described as a system composed of several subsystems. These subsystems work together to ensure a constant internal environment and the survival of the organism. Below are three systems that work closely to ensure your survival. Drag each description to the correct
location in the Venn diagram.

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 d.) homologous; have mammary glands
