MIBO 3500 Exam 1 with correct answers
2026/2027 Updated.
millimeter (mm) - correct answer -10^-3
micrometer (um) - correct answer -10^-6
nanometer - correct answer -10^-9
Microbes - correct answer -Organisms and acellular agents too small to be seen by the unaided eye
Robert Hooke - correct answer -made first compound microscope, coined the term "cell"
Antoine van Leeuwenhoek - correct answer -built single-lens magnifier, first to observe single-felled
microbes
Francesco Redi - correct answer -meat and maggots research, disproved theory that microbes
spontaneously generated
Lazzaro Spallanzani - correct answer -also disproved the spontaneous generation theory, used broth
covered and uncovered
Louis Pasteur - correct answer -proposed the germ theory of disease, idea that the transmission of
microbes is what causes disease, also used Swan neck flasks and broth to disprove spontaneous
generation
germ theory of disease - correct answer -idea that infectious diseases are caused by microorganisms,
important features: transmission, pure culture, colonies
Robert Koch - correct answer -Father of microbiology, four postulates to establish link between
specific microbe and a disease
, Koch's first postulate - correct answer -Microorganism must be present in every case of the disease
and absent from healthy organisms
Koch's Second Postulate - correct answer -Microbe must be isolated and grown in pure culture
Koch's Third Postulate - correct answer -Same disease must result when organism is inoculated in
healthy host
Koch's Fourth Postulate - correct answer -Same microorganism must be isolated from 2nd diseases
host
Limitations of Koch's Postulates - correct answer -Some have immunity, some illnesses have multiple

difficult to test
Lady Montagu - correct answer -Introduces smallpox inoculation in 1717
Edward Jenner - correct answer -Smallpox vaccine (furthers Lady Montagu's work)
Florence Nightingale - correct answer -Used medical statistics to demonstrate the significance of
mortality due to disease during the Crimean War
Alexander Fleming - correct answer -discovered penicillin
Howard Florey and Ernst Chain - correct answer -Purified penicillin
Sergei Winogradsky - correct answer -Discovered lithotrophs, developed enrichment cultures, and
built the Winogradsky column
Detection - correct answer -The ability to determine the presence of an object
