Accepted Answer

Redi's meat and jar experiment

Question 6

Pasteur's swan-necked flask experiment demonstrated that:

Accepted Answer

Microorganisms in the air can contaminate sterile solutions, but spontaneous generation does not occur.

Question 7

Which of the following is the correct sequence of steps in the scientific method as illustrated in the study materials?

Accepted Answer

Observation → Question → Hypothesis → Experiment → Observation → Accept/Reject Hypothesis

Question 8

Which of the following best describes Koch’s postulates for identifying the causative agent of a disease?

Accepted Answer

The suspected agent must be found in every case of the disease, isolated and grown outside the host, cause disease in a healthy host, and be re-isolated from the newly diseased host.

Question 9

Which of the following is a practical application of bioremediation as described in the study materials?

Accepted Answer

Using fungi to detoxify polluted environments

Question 10

Which scientist’s work led to the development of the field of immunology by introducing the first vaccine?

Accepted Answer

Edward Jenner

Question 11

Which of the following statements about viruses is correct based on the images and study materials?

Accepted Answer

Viruses are acellular and require a host cell to reproduce.

Question 12

Which of the following best explains why Pasteur’s experiments with grape juice and yeast were important for the field of biochemistry?

Accepted Answer

They demonstrated that living microorganisms, specifically yeast, are responsible for fermentation, leading to the discovery of enzymes.

Question 13

Which of the following is NOT a contribution of Robert Koch to microbiology?

Accepted Answer

Discovery of penicillin

Question 14

Which of the following best describes the role of microorganisms in the nitrogen cycle?

Accepted Answer

Microorganisms help plants obtain nitrogen by converting atmospheric nitrogen into forms plants can use.

Question 15

Which of the following is a correct application of the Gram stain, as shown in the images?

Accepted Answer

It distinguishes bacteria with thick peptidoglycan cell walls (Gram-positive) from those with thin walls and an outer membrane (Gram-negative).

Question 16

Question 17

Which of the following best describes the main function of serology in microbiology?

Accepted Answer

The study of blood serum and its chemicals and cells that fight infection

Question 18

Which of the following is a correct statement about the scientific method as applied in microbiology?

Accepted Answer

A hypothesis is tested through experiments, and based on the results, it is either accepted, rejected, or modified.

Question 19

Which of the following is a correct example of how microorganisms are used in industry, as shown in the study materials?
