Question

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 b. 1000 C. 200 d. About 50,000 e. 18.000

Answer 1

Number of cells at Slarting (No) = 100 6 Number of generations (n) = Total time. Time for each generation T 3x60 n 20 nea final number of cells (N) = ? N= Noah 10=100x29 = 51,200 about 50,000 cells.
