BIOL 2420 EXAM ONE STUDY GUIDE QUESTIONS AND
ANSWERS 100% CORRECT!!
What are microbes? Answer - microscopic organisms
In what ways microbes are beneficial to humans? Answer - Some are capable
of helping human bodily functions, for example, some speed up the rate of
digestion, produce oxygen through photosynthesis, produce ethanol and
vitamins, disease treatment., and fermented food.
In what ways microbes are harmful to humans? Answer - A small amount of
them can be detrimental to the body by causing disease to spread to us,
causing us to become sick, due to their pathogenicity.
What are the different microbes studied in microbiology? Answer - There are
seven: Bacteria, Algae, Fungi, Archea, Protozoa, Helminths, and Viruses
What are the subdivisions of microbiology which deal with studying these
different microbes? Answer - There are four: bacteriology, Phycology,
Mycology, and virology, this excludes study of Archea, Helminths, and Protozoa
Are all microbes microscopic? Answer - Yes, No microbe can be seen with the
unassisted human eye.
What are the prokaryotic microbes? Eukaryotic microbes? Answer - Bacteria:
Prokaryotic
, Algae: Eukaryotic
Fungi: Eukaryotic
Archea: Prokaryotic
Protozoa: Eukaryotic
Virus: Acellular
Helminths: Eukaryotic
Study the scientists and their contributions to the golden age of microbiology.
Answer - Pasteur: Argued and disproved Spontaneous Generation
Lister: Proved microbes cause infection
Koch: Linking of microbes to specific diseases
Jenner: Vaccination
What are the emerging diseases and the pathogens (virus, bacteria, etc) which
cause them? Answer - Middle East respiratory syndrome: Caused by Middle
East respiratory syndrome coronavirus
Avian influenza A: Primarily in waterfowl and poultry
Methicillin-resistant Staphylococcus aureus: Methicillin resistance
West Nile encephalitis:Caused by West Nile virus
Bovine spongiform encephalopathy : Caused by a prion, an infectious protein
Ebola hemorrhagic fever: contact with infected blood
E. coli : Toxin-producing strain of E. coli
Cryptosporidiosis: Cryptosporidium protozoa
AIDS: Caused by human immunodeficiency virus
Why is water considered as biological solvent? Answer - Nearly everything
comes apart in water due to the oxygen having a negative charge to attract
positive things and hydrogen having a positive charge to attract negative things.
