A) binary; addition of more growth media after the fulture reaches stationary phase
B) diauxic; addition of more growth media after the fulture reaches stationary phase
C) binary; addition of a needed vitamin after it runs out
D) diauxic; addition of a needed vitamin after it runs out
E) diauxic; growth on two carbon sources resulting in a lag after the preferred substrate is depleted; new genes are then induced and growth resumes
