We have learned that one of the target genes induced by phoP is mgrB gene. MgrB acts as a negative regulator by inhibiting the kinase activity of PhoQ. Benches 3 and 9 are trying to remove MgrB gene from Kp strains MKP103 and VT101. If we succeed in removing mgrB gene, which of the following statements would be TRUE? (4/17 lecture, slides 1-15)A. PhoPQ system will stay ON constitutively and so lipid A modification with aminorabinose may always stay ON.B. PhoPQ system will stay ON constitutively but lipid A modification with aminorabinose may always stay OFF.C. PhoPQ mediated gene expressions may stay off and this could increase the virulence of bacterial cells.D. PhoPQ mediated gene expressions may stay ON consecutively, and this could increase bacterial resistance against CAMPs thus increasing virulence.E. Both A and DF. Both B and D

014 10.0 points A block of mass $m$ is pushed a horizontal distance D from position A to position B, along a horizontal plane with friction coefficient $\mu$. Then the mass is pushed from B to A. If the horizontal force pushing the mass from A to B is $\vec{P}$, and the force pushing the mass from B to A is $-\vec{P}$, what is the total work done by friction? 1. $2(P - \mu mg)D$ 2. $-2\mu mg D$ 3. $2(\mu mg - P)D$ 4. 0 5. $+2\mu mg D$

The Newton-Raphson method is a popular technique for finding the real root of an equation. In this case, we are tasked with finding the real root near 2 of the equation x^(4)-11x+8=0 accurate to five decimal places. The given values are a=8, b=2, and tol=1.0×10^(5). a) To find the root of this equation by hand, we can use the Newton-Raphson method to iteratively approximate the root. b) Drawing the flow chart of an algorithm for the solution of this equation by the Newton-Raphson method will help visualize the steps involved in the process. c) Creating an m-script containing a function to solve this equation system by means of the Newton-Raphson Method will allow us to implement the solution in MATLAB. i. The MATLAB Code (m-script) for solving this equation using the Newton-Raphson method will be written on the answer sheet. ii. An explanation (comment) will be added to the MATLAB code to provide clarity on the implementation.
