Derive a partial differential equation describing the evolution of the concentration b(x, t) of a population of bacteria along a water filament. assume that the bacteria reproduce locally at a rate proportional to their concentration, with proportionality constant λ, and that they diffuse with a flux proportional to −bx, with proportionality constant µ. in order to derive the equation, start with an integral principle describing
