Homeostasis is the process of maintaining a cell's environment. This includes the regulation of sodium ion (Na+) concentration within the
cytoplasm. If too much Na+ is inside a cell, how can the concentration be
changed?

A) More Na+ ions will be transported in through membrane protein channels

B) Excess Na+ ions will leave the cell via osmosis

C) More Na+ ions will enter the cell through the plasma membrane

D) Excess Na+ ions will be transported out though membrane protein channels
