22. While relaxing and enjoying a Cup of freshly brewed Kona Coffee, your Swedish Lab Assistant brings you the Results from a detailed Analysis of two Bacteria you isolated on a recent Field Trip to South America. One of these Bacteria (it ʼ s growing in a Petri Plate labeled with Blue Tape so your Swedish Lab Assistant calls these the Blue Bacteria) was isolated near the Summit of Aconcagua, the highest Mountain in South America. The other Bacterium (it ʼ s growing in a Petri Plate labeled with Red Tape so your Swedish Lab Assistant calls these the Red Bacteria) was isolated from the Hot Water Lines of the Hotel in which you stayed in Buenos Aires. It takes a while for the Caffeine to accelerate up your Cranial On-Ramp and for you to realize that -- just as you suspected -- A. Both the Blue Bacteria and the Red Bacteria have a large Percentage of Saturated Fatty Acids in their Membranes. B. Both the Blue Bacteria and the Red Bacteria have a large Percentage of Unsaturated Fatty Acids in their Membranes. C. • The Blue Bacteria have a surprisingly large Percentage of Saturated Fatty Acids in their Membranes. • The Red Bacteria have a surprisingly large Percentage of Unsaturated Fatty Acids in their Membranes. D. • The Blue Bacteria have a surprisingly large Percentage of Unsaturated Fatty Acids in their Membranes • The Red Bacteria have a surprisingly large Percentage of Saturated Fatty Acids in their Membranes

23. Streptococcus lactis is an Aerotolerant Anaerobe, meaning that it -- A. Ignores O 2 . B. Does not require O 2 but grows better in its Absence. C. Does not require O 2 but grows better in its Presence. D. Requires small Amounts of O 2 but is damaged by Atmospheric O 2 Levels. 24. Bacillus subtilis produces Proteolytic Enzymes (G= breaks[-up] proteins) that are used in Laundry Detergents. Such Laundry Detergent Enzymes account for about 30% of the total Worldwide Enzyme Production and represent one of the largest and most successful Applications of modern Industrial Biotechnology. These Enzymes function optimally at Temperatures of 20°C to 60°C and within the pH range of pH 8.0 to 10.5 of a typical Wash Cycle. Bacillus subtilis is a(n) -- A. Acidophile B. Alkalophile. C. Osmophile. D. Halophile. 25. While on a Backpacking Vacation in the Jura Mountains in Southeastern France your Swedish Lab Assistant takes a Spill when climbing some Scree, resulting in a serious Abrasion extending from Hand to Elbow. This Wound clearly requires a Bandage but -- ¡Canasta! ¡Crayola! ¡Cheezy Grits! -- you have no Bandages in your Backpack. Instead, you set-up your Primus, use your Swiss Army Knife to cut Strips of Cloth from your Le Coq Sportif™ Shirt (Brand New!!!), and boil these Strips in Water for 10 Minutes to make what you sincerely hope might be a Sterile Bandage. Which of the following Pathogens might still be a Mischief-Maker within the Bandage, even after this 10 Minute Boiling Step? A.
