Elements such as nitrogen, carbon, and oxygen cannot be made or destroyed they can only change their location by cycling through the biosphere true or false ? ?

True

Explanation:

Chemicals like Nitrogen, Carbon and Oxygen cannot be made or destroyed they can only change their phase and location.

There are several biogeochemical cycle in the environment which keeps the essential nutrient in rotation within the ecosystem.

Such as carbon cycle, nitrogen cycle, phosphorus cycle etc.  

In all these cycles, the nutrient is being continuously cycled between the producer (plants & trees), consumers (animals & human beings) and the decomposers (bacteria’s etc.)  

These nutrients continuously changes their form and place in order to be in a used efficiently.

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.

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
