Identical forces are exerted on the two objects. Which statement is true? The acceleration of object A is three times that of object B. The accelerations of the two objects are equal. The acceleration of object B is three times that of object A.

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.
