Vibrio cholerae (the causative agent of the disease cholera) can grow in the intestinal tract of a human, with a generation time of just 20 minutes! If you ingested water contaminated with feces, and just 100 cells of V. cholerae made it through your stomach to your intestine, how many cells would there be 3 hours later? (Assume that there is no lag phase, the cell begins dividing exponentially as soon as it reaches the intestine) Select one: a 100...

VOLJNO Lactose-fermenting bacteria metabolize lactose using two proteins, one binds external lactose and transports it into the cell, the other breaks down the lactose that comes into the cell. The two proteins are coded for by two genes that are under the control of a single promoter. You carry out a lactose fermentation test on an unknown bacterium and find that the result is positive. All of the following are applicable to this bacterium growing in the lactose broth, EXCEPT:...
