Final answer:
The introduction of a chemical that interferes with quorum sensing in pathogenic bacteria can help fight an infection by inhibiting bacterial communication, disrupting biofilm formation, and reducing virulence.
Step-by-step explanation:
The introduction of a chemical that interferes with quorum sensing in pathogenic bacteria can help fight an infection in multiple ways. By Quorum sensing process bacteria communicate with each other to. By inhibiting bacterial communication, the chemical disrupts quorum sensing, which can prevent the formation of biofilms. Biofilms are complex colonies of bacteria that exchange signals and coordinate the release of toxins. By interfering with quorum sensing, the chemical can also reduce the virulence of the pathogenic bacteria, making them less harmful.
Therefore, the right option is D) All of the above.
