On a hot day, Jorge decides to make a pitcher of cold lemonade. He combines pure water with lemon juice in a ratio of six to one. He adds sugar and ice and stirs all the ingredients together. The properties of the lemonade are that it is cold, yellow, and sweet. (Question:) How would the properties of the lemonade change if the ratio of pure water to lemon juice were three to one? Assume the amount of sugar is the same.

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.
