True or false?
1. When glucose is transported by the phosphotransferase system of E. coli, it moves down it's concentration gradient into the cell
2. E. coli is capable of chemotaxis, however, mutants that are unable to reverse the direction of rotation of their flagella lose this ability
3. Exposing bacteria to suboptimal doses of antibiotics (concentrations of drug that don't effectively inhibit bacterial growth) creates selective conditions for the emergence of drug-resistant mutants
