An engineer constructs a model of a new dam that is to be built above the Danube River. He uses the same type of cement that will be used on the real dam. The dam design is called Arch-22. He tests the miniature cement dam using a pressurized water tank. Which predictions could NOT be made from using a model such as this?

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.
