BIOL 2604 EXAM 1 EXAM WITH
CORRECT QUESTIONS AND ANSWERS
2025
characteristics of cellular life - CORRECT-ANSWERS>>>>>metabolism,
reproduction, differentiation, communication, movement, evolution
applied uses of microbiology - CORRECT-ANSWERS>>>>>agriculture,
energy/environment, disease, food, biotechnology
basic biological science - CORRECT-ANSWERS>>>>>understanding processes
of physiology, ecology, genetics
applied biological science - CORRECT-ANSWERS>>>>>it has and continues
to help us solve many problems relating to health, agriculture, and
industry
robert hooke - CORRECT-ANSWERS>>>>>coined the term "cell"
Antoni Von Leeuwenhoek 1684 - CORRECT-ANSWERS>>>>>First described
bacterial cells as "wee animalcules"
,Ferdinand Cohn (1876) - CORRECT-ANSWERS>>>>>described lifestyle of
endospores-forming bacteria, scientific journal of bacteriology,
developed basic bacteriological practices, developed initial
classification scheme for bacteria, founder of science of bacteriology
Louis Pasteur (1857-1885) - CORRECT-ANSWERS>>>>>microbes in lactic
acid fermentation, yeast in alcohol fermentation, disproof of
spontaneous generation, vaccines (rabies, chicken cholera, anthrax)
Rober Koch (1881-1884) - CORRECT-ANSWERS>>>>>methods for pure culture
of microorganisms, postulates for determination of etiological agents
of disease, cause of tuberculosis
Martinus Beijerinck - CORRECT-ANSWERS>>>>>Developed enrichment culture
technique, microbial selection (only your organisms survive), IDed
aerobic nitrogen fixers, sulfate reducers, sulfate oxidizers,
symbiotic nitrogen fixers, first to describe viruses COULD NOT SEE
THEM
Sergei Winogradsky - CORRECT-ANSWERS>>>>>-Developed concept of
chemolithotrophy
-Winogradsky column
-Microbiologie du Sol (manual about soil organisms)
, Pasteur's experiment - CORRECT-ANSWERS>>>>>- Verified principle that
cells can only come from pre-existing cells
1. Placed samples of broth in flasks with long swan necks and melted
the glass of the necks to bend them into different shapes
2. Boiled the broth in some of the flasks to kill any organisms
present, and left others unboiled (controls)
3. Fungi and other organisms appeared in the unboiled flasks but not
the boiled ones (even after a long time)
4. The broth in the flasks was in contact with air (which had been
suggested was needed for spontaneous generation), but that didn't
occur, so disproved it
5. Snapped necks of some of the flasks to leave a shorter vertical
neck, and organisms were soon apparent and decomposed the broth
6. Concluded that the swan necks prevented organisms from the air
getting into the flasks and that no organisms appeared spontaneously
Koch's Postulates - CORRECT-ANSWERS>>>>>a sequence of experimental
steps for directly relating a specific microbe to a specific disease
eukaryotic cell - CORRECT-ANSWERS>>>>>diploid, nucleus (membrane-
enclosed structure containing genetic info), more complex
