,CHAPTER 01: THE INVISIBLE WORLD
Question 1: Which of the following is true of the microbial world?
A. All microbes are harmful
B. Humans could survive without microbes
C. Many microbes are helpful
D. Most microbes are pathogenic
Answer: C
Rationale: The vast majority of microbes are either harmless or beneficial to humans. Only a small fraction of
microorganisms are pathogenic. Microbes play essential roles in nutrient cycling, digestion, and many industrial
processes.
Question 2: When did humans first suspect the existence of microbes?
A. During the Industrial Revolution
B. In prehistoric times
C. In the last century
D. Within the last 500 years
Answer: B
Rationale: Ancient texts and practices suggest that humans suspected the existence of invisible agents of disease
and decay in prehistoric times, long before microbes were directly observed .
Question 3: Which individual first observed unicellular organisms, which he called "animalcules," using a
microscope he developed?
A. Robert Koch
B. Louis Pasteur
C. Thucydides
D. Antonie van Leeuwenhoek
Answer: D
2|Page SUCCESS!!!
,Rationale: Van Leeuwenhoek, using his handcrafted single-lens microscopes, was the first to observe and
meticulously describe single-celled organisms, which he called animalcules, in the 1670s.
Question 4: The process of heating liquids to kill harmful bacteria without ruining the taste, developed by Louis
Pasteur, is known as:
A. Sterilization
B. Pasteurization
C. Sanitization
D. Lyophilization
Answer: B
Rationale: Pasteurization is a specific heat treatment developed by Pasteur to reduce the number of spoilage
and pathogenic microorganisms in foods and beverages like milk and wine, without significantly altering the
product's quality .
Question 5: Which scientist established a set of postulates to prove that a specific microbe causes a specific
disease?
A. John Snow
B. Joseph Lister
C. Ignaz Semmelweis
D. Robert Koch
Answer: D
Rationale: Robert Koch developed Koch's postulates, a set of criteria used to establish a causative relationship
between a specific microbe and a specific disease. These postulates remain fundamental to medical
microbiology .
Question 6: The theory of spontaneous generation stated that:
A. Living organisms can arise from nonliving matter
B. All cells come from pre-existing cells
C. Microbes cause disease
3|Page SUCCESS!!!
, D. Life only comes from life
Answer: A
Rationale: The theory of spontaneous generation posited that living organisms could originate directly from
inanimate or decaying organic matter. This theory was definitively disproven by the work of scientists like Redi
and Pasteur .
Question 7: Louis Pasteur's famous swan-neck flask experiment disproved which theory?
A. Germ theory of disease
B. Cell theory
C. Spontaneous generation
D. Biogenesis
Answer: C
Rationale: Pasteur's swan-neck flask experiment demonstrated that broth remained sterile even when exposed
to air because dust and microbes were trapped in the curved neck, disproving spontaneous generation and
supporting biogenesis .
Question 8: The first antibiotic, penicillin, was discovered by:
A. Paul Ehrlich
B. Gerhard Domagk
C. Alexander Fleming
D. Selman Waksman
Answer: C
Rationale: Alexander Fleming serendipitously discovered penicillin in 1928 when he observed that a mold
contaminant (Penicillium) inhibited the growth of Staphylococcus aureus on an agar plate .
Question 9: Which of the following is not true of archaeans?
