Quizplus · Accepted Answer

Quorum sensing involves the production and monitoring of signaling molecules, which is used by bacteria to sense the density of cells within their population. Quorum sensing is not used by eukaryotes to sense the presence of bacteria within their environment or population, nor to limit the population density of bacteria. Therefore, option D is the correct choice.
