As a result of antibiotic resistant bacteria, many antibiotics can no longer be used to treat bacterial infections. Many microbiologists worry that a pathogenic (disease causing) strain of bacteria that is resistant to all known antibiotics will become common in populations of bacteria in the near future. Which of the following situations listed below would favor the selection of antibiotic resistant bacteria in a population of bacteria? Situation A. People are given antibiotics for viral infections Situation B . all physicians in a large area decided to treat every child they saw for any reason with penicillin Situation C. People are correctly prescribed an antibiotic for a bacteria-caused illness and do not take the antibiotic correctly. Situation D. Antibiotics are widely prescribed for any type of illness and there is very little follow-up to ensure that these antibiotics are taken correctly. A. situation A B. situation B C. situation C D. situation D E. all situations 2. As mentioned in the question above, some bacteria are resistant to antibiotics. How did the genetic information for antibiotic resistance come about for the first time in a population of bacteria? A. a random mutation in the bacterial population B. antibiotics caused a mutation in bacteria so that bacteria were resistant to antibiotics C. because antibiotics resistance would be useful in the presence of antibiotics, antibiotic resistance came about in bacteria D. all of these choices are a possible way by which antibiotic resistance came about E. none of these choices are a possible way by which antibiotic resistance came about 3. If college education is free, then you dont have to pay every time you attend lecture or lab. This statement is an example of: a . why science cannot prove hypotheses to be true b. an invalid deductive syllogism c. a false prediction from a false hypothesis d. a false prediction from a true hypothesis e. a true prediction from a true hypothesis 4. During the summer in our area, the weather forecast is often something like: a. Highs in the low 90s near the coast, higher inland. Lows in the upper 70s near the coast, lower inland. b. Highs in the high 90s near the coast, lower inland. Lows in the lower 70s near the coast, higher inland. c. Highs in the low 90s near the coast, higher inland. Lows in the lower 70s near the coast, higher inland. d. Highs in the high 90s near the coast, lower inland. Lows in the upper 70s near the coast, lower inland. e. none of these shows the proper trend between coastal and inland temperatures in the summer 5. Which of the following molecules could be found in living organisms?...
