Its A. the energy is stored within the nuclear of the atom
In the above quantity there are 2 oxygen atoms.
Animals use oxygen to convert this food into energy they can use, and to maintain a steady supply of carbon atoms that are necessary for building any animal cells. Respiration also returns carbon dioxide back to the atmosphere as a waste product, where plants can reabsorb it in the process of photosynthesis. hope I helped.
Answer: true
Explanation:
In chemical reactions, an energy barrier exists between reactants and products. The magnitude of this energy barrier determines the rate of reaction. A lesser energy barrier implies that reactants are converted to products faster since the energy required is not too much. On the other hand, a large energy difference between reactants and products will lead to a slow reaction with very poor yield of products if any.
