Explanation:
Detailed explanation-1: -Serial dilution faces some challenges such as; A mistake might occur throughout the distribution of the sample, and the transfer errors result in a less reliable and less accurate transfer. This leads to the highest dilution having the most errors and the least efficiency.
Detailed explanation-2: -In microbiology, serial dilutions (log dilutions) are used to decrease a bacterial concentration to a required concentration for a specific test method, or to a concentration which is easier to count when plated to an agar plate.
Detailed explanation-3: -In pharmacology, serial dilutions are commonly used to determine the required concentration of a compound.
