BIOS 2210- exam 1 UPDATED ACTUAL Questions and
CORRECT Answers
Microbes microorganism - bacteria, archea, eukarya, viruses
Anything too small to be seen w/o magnification
how small are all microbes 1-10 um
Where are prokaryotic microbes found? They can be found everywhere on earth because they are resilient and adaptable
What are the main categories of microbes 1. cellular or acellular
2. Prokaryotic or eukaryotic
3. single-celled or multi-celled
4. archea or bacteria
Mutalism both polulations are benefitted
Amensalism one population is harmed, the other is unaffected
Commensalism one population is benefitted, the other is unaffected
neutralism both populations are unaffected
Parasitism one population is benefitted, the other is harmed
Where are all microbes found in general everywhere except for sterile fields, usually little to no microbes in womb and
central nervous system
pathogen a bacterium, virus, or other microorganism that can cause disease
parasite an organism that lives in or on an organism of another species(its host) and
benefits by deriving nutrients at the other's expense
