Why do water molecules stick to each other? a. they are polar and form covalent bonds. b. they are nonpolar and form hydrogen bonds. c. they are nonpolar and form covalent bonds. d. they are polar and form hydrogen bonds.

D. because Hydrogen bonds cause water to be exceptionally attracted to each other.

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.
