Concept explainers
(a)
To explain: The changes to the red blood cell with an internal salt concentration of 150mM, when placed in beaker of 500mM salt.
Concept introduction: Water is the most abundant, colorless, odorless, and tasteless character that explains the fundamental importance to living organisms. Molecules generally diffuse across a permeable membrane from a higher concentration region to a lower concentration region. Osmosis is the total movement of solvents across the membrane in a reverse movement from the higher concentration region to a relatively lower concentration region.
(b)
To explain: The direction of solute in the cells if the membrane of the cell is permeable to ions.
