WITH CORRECT ANSWERS GRADED A+
◍ Bacillus.
Answer: aerobicgram positivefound in the soilcould survive dessication
◍ cytosol.
Answer: fluid portion of the cytoplasm
◍ Carols Linnaeus.
Answer: established the system of scientific nomenclature
◍ motility.
Answer: ability to move via flagellausually all of them have flagella but not
all some have full movement but some just shake
◍ what knowledge do microbes give humans.
Answer: prevent diseasesallow food storage and prevent food spoilagesstop
transmission of diseases
◍ Woes.
Answer: discovered the 3 domains and they were all based on the sequences
of nucleotides in rRNA
◍ Joseph Lister.
Answer: • discovered phenol: was used to stop surgical would infections •
usually in hospitals : Staphylococcus aures aka staph infection at least 20%
of population is a carrier for the staph infection and they carry it in their
noses
◍ what is the kind of microscope that you use when looking at a virus.
Answer: electron microscope
◍ Endospores.
, Answer: - Spore Formations= sporulation - The most resistant forms of life -
Can resist almost everything - They can deterime if something is sterile
because the Autoclave is something that can kill them and they are still
present than the item is not sterile Most pathogenic types of microorganisms
have endospores in them
◍ archaea.
Answer: ♣ Can resist severe conditions ♣ Lack peptidoglycan ♣ Based off
of Eukaraya ♣ Methanogens• Anaerobic o O2 is toxic • Produce methane ♣
Extreme halophiles• Require salt concentration of around 2.5% o The
normal human salt percentage is around .9% ♣ Hyperthermophiles • Require
growth temperature of around 80 degrees Celsius
◍ what are the different magnifications of the electron microscope.
Answer: 1 mil 2 mil10 mil
◍ Order of the Scientific Method.
Answer: observehypothesispredictionexperimentconsistencytheorylaw
◍ Archaea.
Answer: wall less or wall of pseudomurein (lack NAM and D-amino acids)
◍ How are microbes helpful.
Answer: decompose organic wastegenerate O2produce chemical products
such as ethanol and othersproduce fermented foods ex: vinegar, cheese, and
bread produce products used in manufacturing ex: cellulose and insulin
◍ Molecular biology.
Answer: the study of how DNA directs proteins synthesis protein synthesis-
ribosomes
◍ Microbiology.
Answer: the study of organisms too small to be seen with the naked eye
◍ Eurkarya.
Answer: -animals -Plants - Fungi: • Distinct nucleus • Chitin in cell walls •
Absorb organic chemicals for energy • Yeasts: unicellular • Molds and
