10) If the bacterium Staphylococcus aureus experiences a cost for maintaining one or more antibiotic- resistance genes, what would happen in environments that lack antibiotics? A) These genes would be maintained in case the antibiotics appear. B) These bacteria would be outcompeted and replaced by bacteria that have lost these genes. C) These bacteria would try to make the cost worthwhile by locating and migrating to microenvironments where traces of antibiotics are present. D) The number of genes conveying antibiotic resistance would increase in these bacteria. 11) When nonrandom mating occurs in a population so that individuals prefer to mate with similar individuals, allele frequencies should A) remain the same, but homozygotes will be overrepresented in the population. B) remain the same, but heterozygotes will be overrepresented in the population. C) change and heterozygotes will be overrepresented in the population. D) change and homozygotes will be overrepresented in the population. E) remain the same, at Hardy-Weinberg equilibrium.

Why must the top agar be supplemented with maltose? A) Maltose allows for binding of the phage to the E. Coli and aids in the infection process B) Maltose helps stabilize the phage within the media
Identifying an unknown bacterium is an essential step in the diagnosis and treatment process. Since not every antibiotic is effective against every type of bacteria, knowing what caused a particular infection allows us to make correct prescriptions so patients can recover more quickly. Knowing the cause of an infection also prevents antibiotic resistance as well, since incorrect prescriptions allow bacteria to be unnecessarily be exposed to antibiotics, increasing the chances of developing resistance.

A suspected pathogen is observed from the blood of a diseased mouse. An investigation of the other mice in the area indicates that it is not present in healthy mice. With Koch's postulates in mind, what is the next step to determine whether or not this suspected pathogen is the cause of disease in the mouse? a) Grow the suspected pathogen in a pure culture Ob) Re-isolate the suspected pathogen and show that it is the same as the original pathogen c) Inoculate a healthy mouse with the suspected pathogen O d) Determine whether the organism in the pure culture is the same one as in the original sample
31) To establish a link between a specific bacterium and a skin disease, researchers have shown that the bacterium was present in sick persons but not in healthy individuals. They isolated the bacterium in a pure culture and demonstrated that experimental healthy animals injected with this culture became sick. What other experiment do researchers need to perform to be absolutely sure that the bacterium is responsible for the disease? A) Demonstrate that the bacterium belongs to the pathogenic lineage B) Demonstrate that the bacterium is not able to live outside of humans or animals C) Isolate bacterium from an infected sick animal and demonstrate that it is the same bacterium as the one used for infection D) Isolate bacterium from an infected sick animal and demonstrate that it is susceptible to broad spectrum antibiotics.
