Answer;
B. the cell was unable to maintain a stable internal environment.
Explanation;
-A sodium ion imbalance could cause water to rush across the cell plasma membrane in either direction. Too little water makes the cell shrivel up; too much water makes it burst. The balance between water and electrolytes, such as sodium ions, controls cell integrity.
-Electrolytes are molecules that influence cell fluid regulation. Sodium is the most abundant electrolyte. Too much sodium in the surrounding fluid - or too little in the cells - sucks too much water out of the cells.
-Too little sodium in the surrounding fluid - or too much within the cells -causes cells to swell as their higher sodium concentration draws too much water in, which eventually causes cell and organelle membranes to burst.
