- A.
Theory of life
- B.
Spontaneous generation
- C.
Cells theory
- D.
Theory of mass
Correct Answer
B. Spontaneous generationExplanation
Before 1650, there was a widely held belief that living organisms could arise spontaneously from inanimate materials. This belief was known as spontaneous generation. It was believed that things like maggots could spontaneously appear from decaying meat or that mice could be generated from piles of grain. However, this theory was eventually disproven through experiments conducted by scientists such as Francesco Redi and Louis Pasteur, who provided evidence that living organisms only arise from preexisting living organisms.Rate this question:

Microbiology started after 1650 due to the development of the microscope and the observation of cells.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because microbiology did indeed start after 1650, which coincided with the development of the microscope. The invention of the microscope allowed scientists to observe cells, which led to the discovery of microorganisms and the field of microbiology. Prior to this development, the existence of microorganisms was not known, and therefore the study of microbiology did not exist.Rate this question:

The idea of spontaneous generation was still widespread until the year___
- A.
1860
- B.
1822
- C.
1895
- D.
1723
Correct Answer
A. 1860Explanation
The idea of spontaneous generation, which proposed that living organisms could arise from non-living matter, was widely accepted until the mid-19th century. In 1860, Louis Pasteur's experiments successfully disproved the theory and provided evidence for biogenesis, the concept that living organisms only arise from other living organisms. Therefore, the correct answer is 1860, as it marks a significant turning point in the scientific understanding of the origins of life.Rate this question:

One myth about microorganisms was that infectious diseases and fermentation were due to non-biological processes such as _____ and _____.
- A.
Spontaneous generation and chemical instability
- B.
Heavy mass of the atoms of the compounds & physical instability
- C.
Infected air and chemical instability
- D.
None of the above
Correct Answer
A. Spontaneous generation and chemical instabilityExplanation
The correct answer is "Spontaneous generation and chemical instability". This explanation suggests that the myth about microorganisms believed that infectious diseases and fermentation were caused by non-biological processes such as spontaneous generation (the idea that living organisms can arise from non-living matter) and chemical instability. This implies that people believed that microorganisms could spontaneously generate and cause diseases or fermentation, and that chemical instability played a role in this process.Rate this question:

Which scientist published a report in 1861 examining the doctrine of spontaneous generation?
- A.
Antony van Leeuwenhoek
- B.
Robert Koch
- C.
Louis Pasteur
- D.
Robert Hooke
Correct Answer
C. Louis PasteurExplanation
Louis Pasteur published a report in 1861 examining the doctrine of spontaneous generation. He conducted experiments that disproved the theory of spontaneous generation, which stated that living organisms could arise spontaneously from non-living matter. Pasteur's experiments involved sterilizing broth and then observing that no microorganisms grew in the broth unless it was exposed to air containing microorganisms. This supported the theory of biogenesis, which states that living organisms only arise from pre-existing living organisms. Pasteur's work was instrumental in the development of the germ theory of disease and revolutionized the field of microbiology.Rate this question:

How did Koch's Postulate work? What is the purpose of it?
Correct Answer
using the postulate, Koch, and his coworkers discovered the causative agents of many infectious diseasesExplanation
Koch's Postulate is a set of criteria used to determine the causative agent of an infectious disease. It involves four steps: 1) the microorganism must be present in all cases of the disease, 2) the microorganism must be isolated and grown in pure culture, 3) the cultured microorganism should cause the same disease when inoculated into a healthy host, and 4) the same microorganism must be re-isolated from the newly infected host. By following these steps, Koch and his coworkers were able to identify the specific microorganisms responsible for various infectious diseases.Rate this question:
