In the Osmotic Pressure lab, the results are based upon turbidity measurements. A relatively low turbidity suggests: Select one: a. More bacterial growth b. The culture will be relatively cloudy c. A color change occurred d. Less bacterial growth If the Staphylococcus aureus grew more in a 5% NaCl environment than it did in 2% or 11% NaCl, you would conclude that it is probably a: Select one: a. Extreme halophile b. Osmotolerant c. Intestinal bacteria d. Halophile False negatives are likely in a test with low: Select one: a. Sensitivity b. Specificity c. Experimental variables d. 10% bleach solution e. Sharps container An experimental result that is positive when the microbe of interest was present is a: Select one: a. A false negative b. A false positive c. A true negative d. A true positive e. Low sensitivity

For most cells that have 0.9% NaCl in the cytoplasm, including E. coli, the (non-0%) experimental environments used in the Osmotic Pressure lab are: Select one: a. Hyperosmotic b. Acidic c. Isosmotic d. Hyposmotic To increase turgor pressure in a culture of cells, you would add: Select one: a. Salt water (3% NaCl) b. Saline (0.9% NaCl) c. Distilled water d. Extreme salinity (25% NaCl) A common bacterial species living in the human intestine is: Select one: a. Staphylococcus aureus b. Escherichia coli c. Bacillus subtilis d. Clostridium tetani e. Streptococcus pyogenes In a solution where the solute concentration is high, the water concentration is: Select one: a. High b. Low c. Super duper pressurized d. Unaffected e. Equal Which BSL does not require a primary barrier? Select one: a. BSL-1 b. BSL-2 c. BSL-3 d. BSL-4 e. BSL-5 If a non-infected individual tests positive for the infection, this would be Select one: a. A false negative b. A false positive c. A true negative d. A true positive e. High sensitivity

You are testing GUDI water during a spring rainstorm. Membrane filtration will always give better results with turbid water than MPN tests. True False Enterococcus faecalis and Staphylococcus aureus are both Gram positive microbes that don't grow on Eosin Methylene Blue (EMB), the standard coliform test medium. True False Enterococcus faecalis is a salt tolerant Gram postive fecal microbe that is a good indicator of beach water quality because it lasts longer than E.coli . A persistent indicator means that we are more likely to detect fecal contamination and correct the problem, True False
Two solutions are separated by a semi-permeable membrane (osmotic membrane). Solution A is a 25% glucose solution and Solution B is a 20% glucose solution. Select all cases below that are true as osmosis occurs. There may be more than one correct answer. A. Solution A will decrease in volume. B. Solution B will become more concentrated. C. Water will flow from solution A to B. D. Water will flow equally between the solutions. E. Solution A will increase in volume.
