Question

complete the paragraph. at the start of the video, the concentration of water molecules outside the cell is than it is inside the cell. the water molecules cross the cell membrane in water molecules move from outside the cell to the inside. eventually, the concentration outside the cell is the concentration inside the cell.

Explanation:

In osmosis, water moves from an area of higher water - molecule concentration to an area of lower water - molecule concentration. Initially, if water moves into the cell, the concentration outside is higher. Water moves through the cell membrane by diffusion. Eventually, equilibrium is reached where concentrations inside and outside are equal.

Answer:

At the start of the video, the concentration of water molecules outside the cell is higher than it is inside the cell. The water molecules cross the cell membrane in a process called diffusion as water molecules move from outside the cell to the inside. Eventually, the concentration outside the cell is equal to the concentration inside the cell.
