Fossil fuels are carbon-containing deposits that form deep beneath Earth's 1 point surface. Diana wants to show carbon moving to a location to form fossil
fuels. Which model most accurately shows this process?"
O She sprinkles breadcrumbs onto water and watches them sink
O She bubbles gas through a water sample.
She makes a replica of a volcano and shows magma erupting from it
She blows bubbles into the air and watches them spread

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.

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 would be knowledge about cars!

a physical change is being made.
