Answer:
Key molecules that contain carbon include proteins, nucleic acids, carbohydrates and lipids. Carbon is an integral part of many biological processes, including reproduction, photosynthesis and respiration. We often assume that life in other parts of the universe, if we ever find it, will be carbon-based.
Explanation:
Plate tectonics is the theory that the earth's crust(lithosphere) is separated into plates and that they glide over the mantle(the layer underneath the lithosphere).
Endothermic reactions use or absorbs energy for the process to occur. Exothermic reactions release energy to the surroundings as the process occurs. In endothermic reactions, reactants are more stable than products while in exothermic reactions, products are more stable than reactants.
So the Biosphere can run corectly
No you should tear down all of the power plants because it is a power source that can still go on without something attached to it
