Question

to function properly, a cell must maintain an optimal water balance. cell membranes are permeable to water, so a cells water balance is affected by its surroundings. water molecules pass through the cell membrane via a process known as osmosis. this video shows water molecules crossing the cell membrane via osmosis. complete the paragraph. at the start of the video, there is a lower concentration of water molecules inside the cell than outside the cell. the water molecules cross the cell membrane in one direction. more water molecules move from inside the cell to the outside, until the concentration outside the cell is higher than lower than about the same as the concentration inside the cell.

Explanation:

Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration across a semi - permeable membrane. In this case, water will move until equilibrium (equal concentration) is reached.

Answer:

At the start of the video, there is a lower concentration of water molecules inside the cell than outside the cell. The water molecules cross the cell membrane in one direction. More water molecules move from outside the cell to the inside, until the concentration outside the cell is about the same as the concentration inside the cell.
