Cell membranes contain openings called ion channels that allow ions to move from the inside of the cell to the outside. Consider a typical ion channel with a diameter of 1.0 nm and a length of 10 nm. If this channel has a resistance of 1.0 x 10⁹ Ω, what is the resistivity of the solution in the channel?
