There are times when the male fertility is reduced because of testicular varicoceles , related to varicose veins in the testis in which blood pools. On the basis of conditions required for sperm development, explain the relation of this disorder with the impairment of sperm development. Introduction: The vein swells due to the backflow of blood and enlarges from the accumulation of blood, which is collected there that leads to the formation of varicose vein. The varicose veins are common and they affect more women than men. The varicocele occurs in the testis, known as testicular varicoceles.

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
