BIO 245 EVALUATION EXAM UPDATED QUESTIONS
AND SOLUTIONS RATED A+
✔✔Many microorganisms discourage colonization by pathogens and even
_______________ with them - ✔✔compete
✔✔Hyperthormophilic - ✔✔Very hot loving
✔✔Where do hyperthermophiles live? - ✔✔volcanic hot springs
deep-sea hydrothermal vents
geysers
✔✔Microorganisms live in some __________ places - ✔✔Extreme
✔✔Snow algae - ✔✔They are psychrophillic bacteria in very cold area such as
sea ice, antarctica, marine sediment @ 12°C
They have red pigmented spores
With new adaption causes new protein structure:
more alpha helix and less beta sheets
more polar, less hydrophobic
more unsaturated and shorter fatty acids
✔✔Can microorganisms survive in very cold habitats? - ✔✔Yes
✔✔In Deep sea _______________________ vents, life doesn't depend on light, but
____________ - ✔✔Hydrothermal, chemicals
✔✔Bottom of the ocean is like a desert in being void of life, but
________________________ __________ serve as islands scattered throughout that
are full of diverse life (microorganisms and beyond) - ✔✔Hydrothermal vents
✔✔Hypersaline - ✔✔Very salty
✔✔Hypersaline habitats have what kind of bacteria? - ✔✔Halophilic

✔✔In the Arches national park, Utah (Redstone), how can you tell endolithic bacteria
are present? - ✔✔Darkening of rock
✔✔Where can microorganisms be found in rocks? - ✔✔Between crystals
, ✔✔Where beyond this planet is the highest potential for life? - ✔✔Enceladus, a moon of
Saturn
✔✔What are microorganisms beneficial and useful for? - ✔✔Biotechnology, agriculture,
food and chemical production, mineral extraction, wastewater treatment and
bioremediation
✔✔Bioremediation - ✔✔The use of microorganisms to detoxify toxic or unwanted
chemicals in the environment
✔✔Why does our most fundamental understanding of chemical and physical principles
behind living processes come from the study of microorganisms? - ✔✔Primarily
because of their utility in laboratory: fast growth, small size, and very amenable to
genetic study
