For a given machine, explain why the Mechanical Advantage is usually less than the Ideal Mechanical Advantage? What does this tell you about a machine that has a mechanical advantage vs. a machine that has an ideal mechanical advantage? Provide an example of a machine with a MA and a machine with an IMA. /7 Your answer

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.
