UPDATED 2026
What is the formal definition of science?
✔✔ The systematic study of the natural world (through observation,
experimentation, and evidence-based analysis).
What are the five core principles that comprise the scientific method?
✔✔ 1. Observe the natural world.
✔✔ 2. Formulate a testable hypothesis.
✔✔ 3. Test the hypothesis through controlled experimentation.
✔✔ 4. Develop a theory if results are consistent with the hypothesis and can be
independently duplicated.
✔✔ 5. Establish a scientific law when observations and principles are
consistently found to be true universally under specified conditions.
What principle is stated by "Ockham’s Razor" in scientific reasoning?
✔✔ The simplest explanation (or theory) is usually the correct one (when
competing hypotheses account for the same data).
What is the definition of microbiology?
✔✔ The study of organisms too small to be seen without the aid of a
microscope (microorganisms).
What are five primary specialized branches of microbiology, and what does
each study?
✔✔ 1. Bacteriology: The study of bacteria.
✔✔ 2. Mycology: The study of fungi (molds and yeasts).
✔✔ 3. Algology (Phycology): The study of algae.
, ✔✔ 4. Virology: The study of viruses (noting that viruses are acellular/non-living
infectious agents).
✔✔ 5. Protozoology: The study of protozoa.
What are two notable microbiological phenomena or concepts referenced
historically in the Bible?
✔✔ 1. Leprosy (an ancient bacterial disease caused by Mycobacterium leprae,
frequently referenced in historical and scriptural texts regarding quarantine and
clinical management).
✔✔ 2. Wine and fermentation (early practical applications of microbial yeast
metabolism to convert sugars into alcohol).
Why was wine so important? -ANSWER✔✔1. Contaminated water
2. Alcohol is a preservative
Leprosy info -ANSWER✔✔1. 2000 lepers in the U.S
2. Many treated in LA
3. 1,000,000 lepers in Africa
4. Stay away from armadillos
5. Incubation of Leprosy in 18 years
Hooke (1665) -ANSWER✔✔1. First observation of cells (cork cells)
2. Started Cell theory
Van Leeuwenhoek (1673) -ANSWER✔✔1. First to find live microorganisms
2. Published findings- was discredited because of era
