  We calculate total photon-nucleus and electron-nucleus cross sections $\gamma
A\to X$, $e A\to e^\prime X$ and several cross sections on pion and eta
production in nuclei in the energy regime between the first and the third
resonance region for photon virtualities $Q^2\le 1.0 GeV^2$ within a
semi-classical BUU transport model. In both cases we discuss the varying
influence of several medium modifications on the cross sections for different
values of Q^2.
