7. Zach Ziegler does hamstring curls to increase his hamstring strength. The relative angle at his knee changes from 0 degrees (straight leg) to 130 degrees of knee flexion and back to 0 degrees when doing 1 hamstring curl. What is the total angular distance performed in 1 curl

Less force and energy was applied

One splits the atoms and molecules  the other combines them

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.
