This diagram shows a game. The player has to control the strength of the electromagnets to make a steel ball move through a maze. The electromagnets at B and D are connected to the same control knob. If you turn the knob to the right, the ball moves towards B. Explain how the control knob changes the current in electromagnets B and D to make this happen.

Ibelieve your answer is b.hope 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.
