Answer:
You ingest 20 cells of Salmonella. This bacterium has a doubling time of 30 minutes. After 4 hours, how many of these bacteria would be present in the body (assuming no immune system responses or other biological activities affect its growth)?
240 cells of salmonella
Explanation:
20 cells of salmonella
in 30 mins = 40 salmonella
60 minutes= 60 salmonella
