As the next step, you decide to test various agents to see if they can inhibit quorum sensing in vitro. you know from work done on a related bacterium that short proteins (peptides) can act as inhibitors of quorum sensing by blocking protein-protein binding events required for signaling. you test a large collection of synthetic peptides and find three candidates that appear to interfere with quorum sensing (peptides 1, 2, and 3). in an experiment similar to the one in the previous part, you grow cultures of wild-type (non-mutant) s. aureus to the same standardized high density and measure the amount of toxin they secrete. for this experiment, however, you mix the candidate inhibitory peptides into the growth medium before starting the cultures. the control culture contains no peptide.

He did not infringe upon the policy making powers that he felt the constitution gave congress. but the determination of foreign policy became preponderantly a presidential concern. when the french revolution led to a major war between france and england, washington refused to accept entirely the recommendations of either his secretary of state thomas jefferson, who was pro-french, or his secretary of the treasury alexander hamilton, who was pro-british. rather, he insisted upon a neutral course until the united states could grow stronger. which provides the best objective summary of this excerpt? president washington made a good choice when he decided not to accept the recommendations of his advisors and instead insisted that the united states stay neutral during the war between france and england as president, washington believed that the united states should remain neutral in foreign policy even though he had advisors who recommended that he take sides during the war between france and england. washington did not make policy decisions during his presidency because he did not want to interfere with the policy-making powers that the constitution gave congress. washington refused to accept entirely the recommendations of either his secretary of state thomas jefferson, who was pro-french, or his secretary of the treasury alexander hamilton, who was pro-britis
