Final answer:
Removing microorganisms before sterilization increases the chances of effectively killing them.
Step-by-step explanation:
Before sterilization, removing as many microorganisms as possible enhances the probability of microbial kill. Sterilization aims to completely remove or kill all vegetative cells, endospores, and viruses from the targeted item or environment. By reducing the microbial load before sterilization, the sterilization protocol can more effectively eliminate any remaining microorganisms.
