The burning of coal, a fossil fuel, produces water and carbon dioxide. How is this similar to cellular respiration?
A) Both require high temperatures.
B) Heat energy is lost in both cases.
C) Both involve the breakdown of carbon compounds.
D) Some amount of carbon remains un-oxidized in both cases.

Answer I did this because you didn't have the right chose

Explanation and who gave you this

They did the answer wrong

The greenhouse-gas problem is relatively easy to grasp. All fossil fuels are made up of mostly carbon and hydrogen. When burned, the carbon is converted to carbon dioxide and the hydrogen to water. Each of those reactions produces a slightly different amount of heat.

i got something better   a catchphrase here it is

what the squwock

explanation:

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
