Answer:
the 3ed one hope this helped
Explanation:
<span>When the cell has extra energy (gained from breaking down food that has been consumed or, in the case of plants, made via photosynthesis), it stores that energy by reattaching a free phosphate molecule to ADP, turning it back into ATP. The ATPmolecule is just like a rechargeable battery.

Answer: Diffusion and osmosis
Explanation:
Water, like many molecules, wants to be at equilibrium; it wants to have an equal concentration on either side of the membrane. The movement of water across a membrane to reach equilibrium is called osmosis. Water molecules move through the phospholipid molecules in the cell membrane by osmosis.
Osmosis is a process through which the molecules pass through a semipermeable membrane across a concentration gradient. Water molecules pass from high concentration to low concentration.
