6. Would there be a net flow of water in one direction in the following situations? Explain your answers.
amid [387]

Answer: There won't be a net flow of water in one direction in the situation.

Explanation: The concentration of NaCl inside the cell and its concentration outside the cell is the same. This means that there is equilibrium (a balance) between the inside environment of the cell and the outside environment of the cell. And because there is equilibrium between the two sides there will not be a net flow of water in one direction. The flow of water must be in opposite directions (inside and outside) so as to maintain a balance between the two environments.
