Question

Viruses were first discovered after the development of the porcelain filter, called the Chamberland-Pasteur filter. How did the porcelain filter enable scientists to discover viruses?

a) By allowing the visualization of viral particles under a microscope
b) By separating bacteria from viral particles based on size
c) By facilitating the growth of viruses in culture
d) By preventing the passage of viral particles through the filter

Answer 1

The porcelain filter, called the Chamberland-Pasteur filter, enabled scientists to discover viruses by preventing the passage of viral particles through the filter.

Step-by-step explanation:

The porcelain filter, called the Chamberland-Pasteur filter, enabled scientists to discover viruses by preventing the passage of viral particles through the filter. The development of the porcelain filter, called the Chamberland-Pasteur filter, enabled scientists to discover viruses by preventing the passage of viral particles through the filter.

This filter was capable of removing all bacteria visible under a microscope from any liquid sample, allowing scientists to isolate and study the smaller virus particles that were not removed by the filter. Through the use of the Chamberland-Pasteur filter, scientists were able to demonstrate that there were infectious agents smaller than bacteria responsible for causing diseases, which led to the discovery of viruses.
