front 1 Why are microorganisms hard to see in wet preparations? | back 1 because they move around too quickly and are not stained. They also blend in with their environment. |
front 2 Can you distinguish the prokaryotic organisms from the eukaryotic organisms? Explain. | back 2 eukaryotic cells have organelles bound by membranes (i.e. they're compartmentalized) while much of the cellular machinery prokaryotic cells are floating around freely. |
front 3 Why isn’t the oil immersion lens used in the hanging-drop procedure? | back 3 It uses refraction to increase the resolution, therefore, since the hanging-drop procedure has a different refraction index, the oil immersion lens cannot refract the light correctly, due to its incompatibility. |
front 4 What is the advantage of using Petri plates rather than test tubes in microbiology? | back 4 Gives room for different colonies to grow |
front 5 What are bacteria using for nutrients in nutrient agar? | back 5 Carbon, nitrogen, phosphorus, sulfur, energy |
front 6 What is the purpose of the agar? | back 6 To use a solid agent |
front 7 How could you determine whether the turbidity in your nutrient broth tube was from a mixture of different microbes or from the growth of only one kind of microbe? | back 7 Transfer the cell sample to a petri dish with agar and see if different types of colonies grow. |
front 8 WHAT TWO NAMES DOES SCIENTIFIC NOMENCLATURE ASSIGN? | back 8 GENUS (BEGINS WITH CAPITAL LETTER AND IS ITALICISED) SPECIES (BEGINS WITH LOWER CASE) |
front 9 EUKARYOT INCLUDES ALL OF THE FOLLOWING EXCEPT? | back 9 VIRUSES |
front 10 CRYPTOSPORIDIOSIS CAN BE SPREAD IN WATER SUPPLY. WHAT IS IT CAUSED BY? | back 10 PROTOZOA |
front 11 WHAT ARE PRIONS? | back 11 INFECTIOUS PRETENTIOUS PROTEINS |
front 12 WHAT KIND OF DISEASES DO PRIONS CAUSE? | back 12 MAD COW DISEASE (IN COWS) SPONGYIFORM ENCEPHALOPATHIES (IN HUMANS) AKA Creutzfeldt–Jakob disease SCRAPIE (IN SHEEP) |
front 13 WHAT TYPE OF IMMUNE CELLS DOES HIV DESTROY? | back 13 CD4 CELLS |
front 14 BIOREMEDIATION USES MICROBES TO DO WHAT? | back 14 THEY CLEAN, BREAKDOWN POLLUTANTS & TOXIC WASTE |
front 15 WHAT IS THE SMALLEST COMPONENT OF A PURE SUBSTANCE? | back 15 ATOM |
front 16 AN ISOTOPE OF OXYGEN HAS AN ATOMIC NUMBER OF 8 AND AN ATOMIC WEIGHT OF 18 HOW MANY NEUTRONS DOES IT HAVE? | back 16 10 |
front 17 WATER HAS AN UNEQUAL DISTRIBUTION OF CHARGES AND IS CALLED A? | back 17 POLAR MOLECULE |
front 18 WHAT TYPE OF CHEMICAL REACTION BREAKS BONDS AND THEN FORMS NEW BONDS? | back 18 EXCHANGE REACTIONS OR REVERSIBLE |
front 19 WHY DO SATURATED FATS BECOME SOLID MORE EASILY? | back 19 BECAUSE THE FATTY ACIDS ARE CLOSELY PACKED THERE IS A DOUBLE BOND AND IT CAUSES A KINK IN THE SHAPE. |
front 20 WHICH LEVEL OF PROTEIN STRUCTURE REFERS TO OVERALL 3 DEMENTIAL STRUCTURE OF A POLYPEPTIDE CHAIN? | back 20 TERTIARY STRUCTURE |
front 21 WHAT IS IN THE PRIMARY STRUCTURE? | back 21 STRAIGHT CHAIN OF AMINO ACIDS |
front 22 WHAT IS IN THE SECONDARY STRUCTURE? | back 22 ALPHA HELIX OR BETA HELIX |
front 23 WHAT ARE TWO OR MORE FULLY FOLDED PROTEINS INTERACTING WITH EACH OTHER CALLED? | back 23 QUATERNARY STRUCTURE |
front 24 WHAT IS THE FUNCTION OF DIAPHRAM ON A COMPOUND MICROSCOPE? | back 24 CONTROLS THE AMOUNT OF LIGHT ENTERING THE CONDENSOR LENSE (LEVER ON THE LIGHT) |
front 25 MOST OCULAR LENSES MAGNIFY SPECIMENS BY A FACTOR OF? | back 25 10 |
front 26 OBJECTIVES SMALLER THAN ABOVE .2MM SUCH AS VIRUS CAN BE VIEWED BY? | back 26 ELECTRON MICROSCOPES |
front 27 CAPSULES ARE STAINED BY? | back 27 NEGATIVE STAINING |
