To compare: The costs and benefits of ectotherm and explain the strategies used by ectotherms to adjust their body temperature. Introduction: In order to survive and function properly animals need to maintain pH and internal temperature within relatively narrow limits. The state of the balanced internal environment is known as homeostasis. The body temperature is maintained within these narrow limits despite the changes in surrounding temperature through a process called thermoregulation. Ectotherms are those animals, which depend on the environment for their body heat, and it keeps changing with the change of temperature in the surroundings

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
