Rosina flicks a Super Ball horizontally from the top bunk of her bunk bed, 2.58 m from the floor. The Super Ball lands on the floor, 1.36 m from the edge of the bed. Calculate the velocity of the Super Ball as it left the bed.

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.

The answer would be a
