|
|
allows for precise measurement of concentration of a sample
|
|
|
allows isolation of pure cultures of microorganisms from mixed populations
|
|
|
allows for preparation of solutions with a known concentration

Explanation:
Detailed explanation-1: -Serial dilution has many advantages: the materials necessary are typically already present in the lab and require no special engineering. Conditions can be adjusted as the experiment progresses (e.g., drug concentrations increased as drug resistance improves).
Detailed explanation-2: -Purpose of Serial Dilution In microbiology, it allows for the estimation of the concentration (number of organisms, bacteria, viruses, or colonies) of an unknown sample by backtracking the measured concentration of the most diluted solution to the unknown concentration.
