a successful experiment often leads to more questions.
true false
i think it might be true because of all of the "what if" and "if this" questions that come up.

I would say true as well because something new can always be improved so there might be questions about adding things to the experiment

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.
