Darren is a wildlife biologist studying deer and wolf species in a nature reserve. He wants to know what is causing a decrease in the wolf population within the nature reserve. What should Darren do next to find the answer to his question? A. Formulate a question about the wolf and deer populations in the reserve
B. Research causes of wolf population decline within other nature reserves
C. Make a prediction explaining why wolf populations are decreasing
D. Create controlled variables for a wolf population study of the reserve

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.
