Quizplus · Accepted Answer

Quorum sensing is a communication system used by bacteria to regulate gene expression based on their population density. When bacteria reach a certain threshold population size, they can coordinate the expression of virulence factors and other genes to enhance their survival and infection potential. Therefore, quorum sensing allows the bacteria to sense when their numbers are high enough to overcome the host immune response and initiate an infection. The other options (B, C, and D) are not directly related to this mechanism.
