The difference between oxygen 16 and oxygen 18. Introduction: An isotope is defined as an element having the same atomic number but a different mass number. In the modern periodic table, elements are arranged according to their increasing atomic number. The symbol is derived as X Z A . Where X represents the chemical formula of the element present in the periodic table. A is the atomic mass which is equal to the sum of a number of protons and number of neutrons. Z is the atomic number which is equal to the number of protons. The nucleus is defined as the sum of a number of neutrons and protons. p + → p r o t o n n 0 → n e u t r o n e − → e l e c t r o n Isotopes are defined only in the modern periodic table.

Summary Introduction

To analyze:

The difference between oxygen 16 and oxygen 18.

Introduction:

An isotope is defined as an element having the same atomic number but a different mass number. In the modern periodic table, elements are arranged according to their increasing atomic number. The symbol is derived as ${}_{Z}^{A}X$ .

Where X represents the chemical formula of the element present in the periodic table.

A is the atomic mass which is equal to the sum of a number of protons and number of neutrons.

Z is the atomic number which is equal to the number of protons.

The nucleus is defined as the sum of a number of neutrons and protons.

$\begin{array}{l} p^{+} \to p r o t o n \\ n^{0} \to n e u t r o n \\ e^{-} \to e l e c t r o n \end{array}$

Isotopes are defined only in the modern periodic table.

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
