Question
Chapter 32, Problem 1FIB
Summary Introduction
Introduction:
In open circulatory system, the blood is not held in blood vessels, rather it circulates through the body cavity, and the cells and tissue are bathed in blood. In the closed circulatory system, blood is present in blood vessels and never gets out in the body cavity.
Expert Solution & Answer
Answer to Problem 1FIB
Correct answer:
Animals with open circulatory systems utilize a fluid called hemolymph that serves the function of both blood and interstitial fluids. This fluid is passed among chambers in the body that are collectively called the hemocoel.
Explanation of Solution
Insects, mollusks, and other arthropods contain open circulatory system in which blood circulates through the body cavity, and bathes organ directly in it. In open circulatory system, interstitial fluid and blood are not separated, and collectively they form hemolymph which is present in the cavity termed as hemocoel.
Conclusion
In open circulatory system, hemolymph is present in the body cavity termed as hemocoel.

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.

- There is currently a H5N1 cattle outbreak in North America. According to the CDC on Feb 26*: "A multistate outbreak of HPAI A(H5N1) bird flu in dairy cows was first reported on March 25, 2024. This is the first time that these bird flu viruses had been found in cows. In the United States, since 2022, USDA has reported HPAI A(H5N1) virus detections in more than 200 mammals."
