How can you explain the substantial lag between a signal and response in the phylum Porifera?
A)Lag occurs because sponges are asymmetrical.
B)Lag occurs because sponges show no cephalization.
C)Lag occurs because action potentials in cells of sponges are slow compared to action potentials in neurons.
D)Lag occurs because the signal has to be very strong in order to see any response.

The lag occurs because action potentials in cells of sponges are slow compared to action potentials in neurons. This delay in the transmission of the signal results in a substantial lag between a signal and response in the phylum Porifera.
