A roller coaster model is shown below. Which answer choice correctly describes the roller coaster cart’s kinetic and potential energy?

Cin carbonh in hydrogeno in oxygen

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.

Ibelieve the answer is d. macula  hope my answer has you : )
