Chapter 19, Problem 1RR
Summary Introduction

To describe: The general principles of the control of body temperature.

Introduction: The homeostatic control of body temperature is called thermoregulation. Constant body temperature is maintained through the balance between heat gain and heat loss.

Expert Solution

Explanation of Solution

Human body temperature is controlled due to the external environment and changes in the metabolic rate. In the skin, there are peripheral thermoreceptors that regulate the skin temperature. In the deep body structure, the central thermoreceptors regulate the core temperature of human body.

Summary Introduction

To determine: The conditions that make the skin of a lady feel warm and moist.

Explanation of Solution

A 33-year-old lady discusses with her physician about the repeated increasing irritability, nervousness, and palpitations. She explained that she feels some annoying conditions in a room while everyone is comfortable with the condition. Unusually, her skin is moist and warm. Due to this, she lost some weight.

In the skin, there are peripheral thermoreceptors that regulate the skin temperature. In this case, the peripheral chemoreceptors of the skin have an effect on the hypothalamus that causes the skin to feel warm and moist.

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
