Consider an infinitely long line of charge having uniform charge per unit length 4.6 µc/m. determine the total electric flux through a closed right circular cylinder of length 9.6 m and radius 17 m that is parallel to the line charge, if the distance between the axis of the cylinder and the line of charge is 4 m.

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.
