The influence of elevation on the Pika range, to check the hypothesis whether the pika range is shifting to higher elevation due to climate change or not, and the limitations in describing the patterns in nature in comparison with a controlled experiment. Introduction: The Pika are closely related to the rabbit, sharing short limbs, a fairly spherical body, a fur coat, and no external tail. However, Pika has shorter, rounded ears. The Himalayan mountains house the large-eared pika, which are generally known to be found at elevations of more than 6,000 meters or about 20,000 ft. The American pika is extremely sensitive to heat. They have poor fecundity and are susceptible to snowfall declines. They also have limited ability to disperse.

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
