In the Following Schematic Diagram, the Estimated Attractive or Repulsive

Short Answer

In the following schematic diagram, the estimated attractive or repulsive force between two adhesive cells is plotted as a function of distance between the cells. The dashed curve represents a condition under which the cells express cadherin but not N-CAM. The other two curves represent conditions under which both cadherin and heavily sialylated N-CAM are expressed. In one of the conditions, however, the ionic strength of the medium has been artificially increased by addition of salt. Which curve (1 or 2) do you think represents the high-salt condition? Write down 1 or 2 as your answer.
