The different phases of cardiac cycle; chambers depolarize and repolarize; contraction and relaxation and its corresponding ECG waves; heart sounds, blood moves in or out of atria; blood volume; and pressure changes in left and right ventricles and aorta. Introduction: The cardiac cycle is a rhythm that is termed by the duration of one heartbeat to the other beat. A typical heartbeat consists of two stages namely diastole and systole. Heart muscles to relax and its chambers to be filled with blood is termed as diastole, and this beat makes the “lub” sound. Contraction of heart muscles and ejection of blood by the chambers of the heart are termed as systole, and this makes the “dub” sound of the heart. Cardiac cycle is illustrated diagrammatically by “Dr.CarlJ.Wiggers,” and henceforth the cardiac cycle is named as Wiggers diagram.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
