answer:

Definitely the burning of coal. Coal produces a crazy amount of carbon when burned. It also takes a lot of carbon to make coal, but also respiration, so 50 50 chance on those two

Explanation:

answer: Respiration

Explanation:

Respiration is defined as the break down of organic food substances in the presence of oxygen within the cell leading to the release of energy (that is stored)

It can be represented by the equation:

C6H12O6 + 6O2 --> 6H2O + 6CO2 + Energy (in form of ATP)

Thus, the main purpose of cellular respiration that takes place in a cell is to generate and store energy required by the whole body.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
