16. You use one of our MIC 103L Stage Micrometers to calibrate your Sputnik’sEyepiece Micrometer. Using its single Lens (with a Yellow Ring) you find that 33.3 Eyepiece Micrometer Units span 100 μm on our Stage Micrometer. You perform a Wright’s Stain of a Human Blood Smear. When you look at this Human Blood Smear with your SputnikMicroscope a Human Red Blood Cell (RBC or Erythrocyte [G= red cell]) spans just a wee Bit more than two (2) Eyepeice Micrometer Units. Approximately how large is a Human Red Blood Cell? A. ~ 5.0 μB. ~ 7.0 μC. ~ 9.0 μD. ~ 11.0 μ

MIC 103L Exam 1 Page 1217. Your Lab Partner did the Gram Stains of your Enteric Isolate (which is Enterobacter aerogenes) and your Bacillus sp. Soil Isolate. Your Lab Partner made a Smear of your Enterobacter aerogenes, allowed this Smear to Air Dry for 20 Minutes and then Heat-Fixed this Smear. Your Lab Partner added Crystal Violet and then went out into the Hallway to answer a Text Message. After an Absence of nearly 10 Minutes your Lab Partner completed this Gram Stain, following the Instructions in the Lab Manual. Your Lab Partner made a Smear of your Bacillus sp. on a separate Slide, allowed this Smear to Air Dry for 20 Minutes and then Heat-Fixed this Smear. Your Lab Partner did all the Gram Stain Steps following the Instructions in the Lab Manual up to the Safranin Step. Your Lab Partner added Safranin and then went out into the Hallway to answer another Text Message. After yet another Absence of nearly 15 Minutes your Lab Partner completed this Gram Stain, again following Instructions in the Lab Manual. Which of the Following represents the Appearance of your Lab Partner’s Gram Stains of your Enterobacter aerogenes and your Bacillus sp.? A. • Your Lab Partner’s Enterobacter aerogenes will be Pink. • Your Lab Partner’s Bacillus sp. will be Pink. ___________________________________________ B. • Your Lab Partner’s Enterobacter aerogenes will be Purple. • Your Lab Partner’s Bacillus sp. will be Pink. ___________________________________________ C. • Your Lab Partner’s Enterobacter aerogenes will be Pink. • Your Lab Partner’s Bacillus sp. will be Purple. _____________________________________________ D. • Your Lab Partner’s Enterobacter aerogenes will be Purple. • Your Lab Partner’s Bacillus sp. will be Purple.
MIC 103L Exam 1 Page 1318. Your Lab Partner prepares Smears of (from Left to Right) Bacillus cereus, Staphylococcus epidermidis and Escherichia coli (E. coli) on a single Slide, allows the Smears to Air Dry and then Heat Fixes these Smears. Following Gram Staining, your ever-helpful and hard-working TA looks at all three Smears on this Slide and seems very pleased with the Result. Which of the Following represents what your ever-helpful and hard-working TA saw on this Slide?
