- Aheterotrophs
14[blank_start]auxotrophs[blank_end] cannot synthesise an essential organic compound

24The overall biofilm charge is characteristically negative?
- AVerdadero
- BFalso
25why can't antibiotic tobramycin interact with a biofilm but ciprofloxacin can?
- ABecause ciprofloxaccin is stronger than tobramycin
- Bbecause ciprofloxacin is smaller so can fit into the biofilm
- Cbecause tobramycin is positivley charged so the opposite charges of the biofilm prevents interaction.
