There is a higher sodium concentration on the inside of the cell than there is on the outside of the cell. How will the sodium particles move and by what process?

Sodium will move from the outside of the cell to the inside of the cell by osmosis.

The extracellular environment is hypertonic.

The intracellular environment is hypotonic in relation to the extracellular environment.

To reach isotonicity, either sodium from the extracellular environment will have to enter the cell via diffusion or water will have to drain from the cell out to the ECM via osmosis

Therefore, what do you think?
I can eliminate A and B for you because in osmosis, water moves.

If the solute has to move, it will always move from hyper to hypotonic.
