Chapter 64, Problem 1.1A
Describe the relative thicknesses of the walls of the heart chambers of the fetal pig.
Expert Solution & Answer
Summary Introduction
To determine:
The comparison between the relative thickness of the walls of the heart chambers of the fetal pig.
Introduction:
The circulatory system of a pig contains a four-chambered heart that pumps blood to and from the lungs and other body parts. The blood transports back to the heart via veins and the blood is transported to the other body parts by arteries.
Explanation of Solution
There are four chambers in the heart of the fetal pig, the right ventricle, the right atrium, the left ventricle, and the left atrium. The walls of the atrium are much thin as compared to the ventricle. Moreover, the left ventricle is much thicker than the right ventricle.
Conclusion
The walls of the atrium are much thin as compared to the ventricle. Moreover, the left ventricle is much thicker than the right ventricle.

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." List and describe two mechanisms that could lead to this H5N1 influenza strain evolving to spread in human: Mechanisms 1: Mechanisms 2: For the mutations to results in a human epidered they would need to change how the virus interacts with the human host.

The cmu operon is activated when Pep 1 is added to the growth media. Pep1 is a peptide that when added extracellularly leads to activation of the Cmu operon. Pep1 cmu-kinase cmu-regulator You also have these genetic components in other strains: b) An alternative sigma factor, with a promoter activated by the cmu-regulator, that control a series of multiple operons that together encode a transformasome (cellular machinery for transformation). c) the gene cl (a repressor). d) the promoter X, which includes a cl binding site (and in the absence of cl is active). e) the gene gp (encoding a green fluorescence protein).
