Answer :
Final answer:
The question describes a process of bacterial dilution, where a small quantity of bacteria from a broth is mixed with a larger volume of another substance, thereby reducing the concentration of bacteria in the resulting solution.
Explanation:
The process described in the question pertains to dilution, a common method used in microbiology to reduce the concentration of microorganisms such as bacteria in a sample. In this instance, you are removing 0.1 ml of bacteria from a source such as a broth, and mixing it with 99.9 ml of another substance, which could be more broth or water. The resulting mixture will contain a diluted quantity of the original bacteria. This process often allows for easier study and manipulation of the bacteria within a lab setting. For instance, it might help to decrease their concentration to a manageable level or ensure that they are evenly dispersed within the solution.
