The drug, penicillin, is secreted by the fungus Penicillium. How does Penicillium escape the effects of the penicillin it secretes? {Ans: Penicillin targets peptidoglycan in the bacterial cell wall. Penicillium is a fungi which is a eukaryotic cell and doesn't have peptidoglycan to attack.}rigid and porous, gives the cell shape and protects from bursting {Ans: cell wall}Where would you expect to find a barophile? {Ans: at the bottom of a lake}Acidophiles would be expected to grow best at a pH of {Ans: 3}Using toilet bowl cleaner and nonionizing radiation to inanimate surfaces only removes or kills vegetative bacteria. The term that best describes this action is: {Ans: disinfection}How can fimbriae make a bacterial cell more virulent? How can a capsule make a bacterial cell more virulent? {Ans: We describe a pathogen (bacteria, viruses, etc.) as virulent when it is either better able to infect and cause disease or cause more harm to the host due to factors such as presence of fimbriae and capsules. Fimbriae are short, hair-like structures that are attached to the cell membrane. They extend from the cell and make the cell "sticky." The fimbriae allow the cell to attach to
