Answer:
diffusion and osmosis
Explanation:
diffusion is the movement of molecules across the membrane from an area of high concentration to an area of low concentration occurring with or without the help of membrane protein. Osmosis is the diffusion of water molecules.
Answer:
the answer would be carbon molecules. When glucose is broken in half during glycolysis, 3 carbon molecules are produced. hope this helps. :)
Answer:
C. Oxygen supply
Explanation:
Autotrophs make their own food with carbon dioxide and create oxygen as a byproduct. Heterotrophs need oxygen to create energy and create carbon dioxide as a byproduct. Therefore, if there are no autotrophs, the carbon dioxide in the air won’t be able to be used to turn to oxygen, which heterotrophs need. The heterotrophs will use up all of the oxygen in the air, leaving lots of carbon dioxide behind. This is why we need plants and trees! Thus, the answer is C.
I hope this helps! :)
