Chapter 1
The principle that organisms cause certain diseases is called the
Germ Theory of Disease
The disproving of spontaneous generation led to an era referred to as the
Golden Age of Microbiology
John Tyndall's experiments in the 1800s showed that microorganisms remained in some broths even after boiling for 5 hours. He later realized that the results of his experiments were due to the presence of endospores. Pasteur might have had results similar to Tyndall's if he had used which material(s) to make his broths? a) hay b) soil c) yeast extract d) sugar
a) hay b) soil
The concept of living things arising from vital forces in non-living or decomposing materials was known as which of the following: a) deductive reasoning b) spontaneous generation c) biogenesis d) germ theory of disease
b) spontaneous generation
Some scientists were skeptical of Pasteur's results because they...
could not reproduce his results
John Needham's experiments in the 1700s showed that broths that had been boiled and then sealed with a cork...
could still give rise to microorganisms
Which organisms typically lack a membrane-bound nucleus? a) algae b) yeast c) protozoa d) archaea e) bacteria
d) archaea e) bacteria
Unlike the term microorganism, the term microbe also includes a) bacteria b) fungi c) protozoa d) viruses
d) viruses
For the name Streptococcus pyogenes, the first part (Streptococcus) indicates the
genus
Lazzaro Spallanzani's experiments in the 1700s showed that flasks of broths that had been boiled for long periods of time and sealed...
remained sterile
Who helped disprove spontaneous generation?
Pasteur
