3. (8 pts) Small stray capacitances can often affect measurements of voltage across the cell membrane. The diagram below represents a sharp glass microelectrode impaling a cell. $R_e$ represents the electrode resistance, while $C_s$ represents the stray capacitance. Suppose $R_e = 100 \, M\Omega$ and $C_s = 10 \, pF$. The resting membrane potential of the cell is 0 mV and the cell generates a rectangular pulse stepping the membrane voltage to 100 mV for 4 ms. 100mV 4ms $R_e$ $V_o$ to amplifier $C_s$ a. (3 pts) For the "RC" circuit above, what is the time constant "$\tau$"? b. (4 pts) In the space below, plot the time course of $V_o$ before, during and after the rectangular pulse. c. (1 pt) Suppose $R_e$ was halved (from 100 MΩ to 50 MΩ) draw the effect on the plot above.

true or false. migration of the lymphoid cells from the bone marrow to central lymphoid organs occurs during the first phase of the immune response - generation of clonal diversity. Also, during this first phase, these cells undergo a series of cell division, and differentiation that results in the formation of naive immunocompetent B cells and T cells. these cells enter the circulation and enter into the secondary lymphoid cells, like the spleen and lymph node. the clonal selection phase is initiated by exposure to a foreign antigen.a. true. b. false.
