Question
Chapter 6, Problem 6A
Summary Introduction
Introduction:
Atoms are neutral. They do not have an electric charge. To form a stable atom the outermost energy level should be either empty or completely filled. Some atoms tend to donate or accept electrons to empty or filled the outer energy level in order to be stable. An atom that has lost or gained one or more electrons becomes an ion and carries an electric charge.
Expert Solution & Answer
Answer to Problem 6A
Correct answer :
The correct answer is option (A) electron gain
Explanation of Solution
Explanation/justification for the correct answer :
Option (A) electron gain. Chlorine has seven electrons in its outer energy level and needs just one electron to fill it. When chlorine accepts (gains) an electron from a donor atom, chlorine becomes a negatively charged ion (Cl -). So, the correct answer is option (A).
Explanation for incorrect answer :
Option (B) electron loss. Chlorine has seven electrons in its outer energy level and it needs only one electron to feel the level. Therefore, no electrons should be needed to donate. So, this is an incorrect option.
Option (C) proton gain. Atoms do not gain protons. The number of protons remains the same for an atom. So, this is an incorrect answer.
Option (D) proton loss. Atoms do not lose protons. The number of protons remains the same for an atom. So, this is an incorrect answer.

- 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.

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. In the case of mutations that may promote an epidemic, provide an example for: a protein that might incur a mutation: how the mutation would change interactions with cells in the respiratory tract (name the receptor on human cells) List two phenotypic consequence from this mutation that would increase human riskarrow_forwardYou have a bacterial strain with the CMU operon: a) As shown in the image below, the cmu operon encodes a peptide (Pep1), as well as a kinase and regulator corresponding to a two-component system. 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).
