Question
Chapter 19, Problem 1CRQ
Summary Introduction
To explain: The difference between cleavage and the cell division taking place in cells after cleavage.
Introduction: The tremendous alterations occur in the cell number, organization, as well as complexity between fertilization and physical maturity. Only a single cell is present at fertilization and at maturity, there are around 75 trillion cells in the body. The cell division is accountable for the increase in the number of cells.
Expert Solution & Answer
Explanation of Solution
| Cleavage | Cell division |
| Cleavage is a process in which a sequence of cell divisions takes place within the zygote and with each division, the cell becomes smaller. | In cell division, after each division, the cell grows. It is essential for survival even after the completion of development. |

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.
