b. biodegradable materials like food, wood, and leaves are not considered pollution.
c. petroleum byproducts and fuels end up as pollution principally from oil spills.
d. pesticides and herbicides do not commonly become water pollutants.

Explanation:

Mine wastes affect surface water quality and quantity groundwater quality and quantity, soils, air quality,etc.

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.
