For the amplifier of Fig. 5.29(a) find an expression for the bias voltage VGSV_{G S}VGS at which the magnitude of voltage gain is at its largest value. What is the value of the gain? What is the maximum allowable signal swing at this bias point? Comment on the practical suitability of this bias point.

Show that the function ψ(x)=Aeikx\psi(x)=A e^{i k x}ψ(x)=Aeikx, where AAA is a constant and kkk is given by Eq. 38-11, is a solution of the time-independent Schrödinger equation for the case U=0U=0U=0.
Using the stickleback data as evidence, explain how the frequencies of particular traits can change from generation to generation in response to selection pressures (in this case the type of predator present in the environment):______________________________.
