Which of the following research questions would best guide an investigation of the link between the structure of the signaling molecules and the evolution of quorum sensing? vie Previ (A) Do these molecules require the same receptors in each bacteria species to generate a response? (B) Did these species evolve from a common ancestor that used a similar signaling molecule?
