• What is the difference between center of mass and center of gravity?

Center of mass is the point where distribution of mass is equal in all directions, and does not depend on gravitational field. Center of gravity is the point where distribution of weight is equal in all directions, but unlike center of mass, it does depend on gravitational field.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
