When biologists studied photosynthesis, they used an isotope of oxygen called 18o. it will not harm the photosynthesis process but is used to track where the atoms go during the process. if the scientists used this radioactive oxygen in the carbon dioxide, in which molecule would the oxygen end up?

maybe because its impossible for balloons to lift a whole entire house.

a chain link fence because there so tiny even my albino donkey can't get out

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
