A red blood cell has an intracellular concentration of 300 mOsM of nonpenetrating solute. What best describes a solution containing 100 mM NaCl and 150 mM urea relative to the red cell?
Urea is isosmotic to the intracellular fluid of red blood cells, but because the membranes of the blood cells are permeable to urea. Urea enters the cell at a m...
