Chap01, Chapter 1 Multiple Choice

• Who was one of the early natural philosophers who coined the name “cella” for the empty

cork spaces that became the word we use today, “cells”?

• Robert Hooke
• Zacharias Janssen
• Francesco Stalluti
• Giovanni Faber

Ans: A

• Leeuwenhoek made lenses that allowed him to magnify objects more than 200X. However,

he failed to promote scientific inquiry because:

• he didn't share his drawings with other scientists.
• he didn't reveal how he ground the lenses and no one else was doing it that well.
• he limited his research to pond water
• it was only a hobby and he didn't live very long

Ans: B

3. Leeuwenhoek was the first person to:

• see viruses.
• use a microscope.
• describe bacteria.
• suggest animalcules caused disease.

Ans: C

• Francesco Redi is famous for performing one of the first experiments over the debate

regarding spontaneous generation. What was his experiment?

• He boiled some mutton gravy and sealed the tops with corks.
• He covered some jars of meat with gauze and left others open. The covered jars did not

develop maggots, the uncovered ones did.

• He showed that mice will appear with damp rags and rice. 1 / 4

• He boiled broth for longer periods of time and sealed the tops with melted glass.

Ans: B

• did not attempt to prove or refute the idea of spontaneous generation.
• Francesco Redi
• Robert Koch
• Lazzaro Spallanzani
• Louis Pasteur

Ans: B

• Which one of the following would be consistent with the idea of spontaneous generation?
• Microorganisms may be cultivated on solid laboratory media.
• Insects are important in the transmission of disease.
• Sick people give rise to microorganisms in their body.
• Disinfection is essential to prevent the spread of microorganisms.

Ans: C

7. Spallanzani’s experiments showed that:

• viruses were transmitted by water.
• spontaneous generation occurs.
• miasma was the cause of disease.
• experiments can be modified to test a hypothesis.

Ans: D

Page: 8

• Which pair of scientists were antagonists during the same period of history?
• Pasteur and Ehrlich
• Koch and Leeuwenhoek
• Spallanzani and Needham
• Pasteur and Snow

Ans: C 2 / 4

9. Semmelweis showed that the transmission of disease could be interrupted by:

• killing disease-carrying mosquitoes.
• disinfecting water supplies.
• pasteurizing milk.
• washing hands in chlorine water.

Ans: D

10. In 1854, John Snow determined that contaminated water transmits:

• smallpox.
• cholera.
• influenza.
• anthrax.

Ans: B

11. John Snow traced the source of an 1854 outbreak of cholera to:

• consumption of contaminated beef.
• an increase in infected mosquitoes.
• yeast cells on contaminated apples.
• a contaminated municipal water supply.

Ans: D

• Who was Edward Jenner?
• He was a surgeon who observed cowpox could provide immunity for smallpox.
• He was a physician who discovered washing your hands can reduce disease transmission.
• He was the first to see a pathogen that causes disease.
• All of the above are correct.

Ans: A

• What was Christian Ehrenberg responsible for naming in the 1830's?
• He gave the name "vaccines."
• He gave the name "eukaryotes".
• He gave the name "bacteria".
• He gave the name "cells". 3 / 4

Ans: C

14. The classical Golden Age of microbiology came to an end partly due to the:

• fact that all infectious diseases were known.
• death of Anton van Leeuwenhoek.
• the beginning of World War I.
• end of the Renaissance.

Ans: C

• Pasteur’s study of fermentation was critical to the development of microbiology because:
• fermentation chemistry occurs in the living body.
• it showed that microorganisms bring about chemical changes.
• it demonstrated that yeasts are microorganisms
• the body undergoes rapid fermentation after death.

Ans: B

16. Pasteur’s studies proved that alcohol was a fermentation product of:

• bacteria.
• yeasts.
• algae.
• a natural chemical process not involving living organisms.

Ans: B

• Pasteur first suggested that bacteria could cause disease in humans by showing that bacteria

could:

• contaminate canned foods.
• cause plant diseases.
• sour wine.
• infect animals.

Ans: C
