Chapter 10.4, Problem 1TQ
Summary Introduction

To review:

The following:

1. The direction of rotation of bacillus when an attractant is added.

2. The interval between clockwise and counterclockwise switching when mutants cheY,cheA,cheZ, and cheR are tethered to the slide and attractants are added.

Introduction:

The movement of an organism in response to a chemical stimulus is defined as chemotaxis. Organisms like bacteria can direct their movement according to certain chemicals present in the environment that help them to find food by swimming toward the food. The microbial cells move toward or away from a stimulus using different appendages.

For a bacterial exotoxin with a typical A-B type toxin structure, removal of the A portion of the toxin would result in which of the following? The B portion remaining would still be able to bind to the target cell, but would not have toxic effects The remaining B portion would enter the cell and carry out its toxic activity, such as ADP-ribosylation The remaining B portion would cause inhibition of protein synthesis Nothing would happen because the A portion is responsible for binding to the target cell. The remaining B portion would still induce cell lysis Please answer asap and in short and content should not be palgarised please
Gram staining is a common technique used to differentiate two large groups of bacteria based on their different cell wall constituents. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with. Alternatively, Gram negative bacteria stain red, which is attributed to a thinner peptidoglycan wall, which does not retain the crystal violet during the decoloring process - s. epidermidis a gram-positve coccus - E. coli a gram-negative bacillus  - C. xerosis a gram-positive bacillus  How does each organism fulfill a specific niche based on the information provided above?
Bacterial growth depends on many environmental factors, including the temperature of the environment. Since microbes can survive in a certain range of temperatures and will thrive at a temperature, understanding these variables allows for control of their growth. This understanding can be used, for example, to preserve certain foods or to treat infections. This lab simulation will use an instrument called a spectrophotometer. This instrument quantitatively measures the amount of light that is absorbed or transmitted by molecules in solution a) In your own words give an introduction to the microbial growth and the effect tempature has. b) In your own words explain the importance of the spectrophotometer in regards to microbial growth. c) In your own words give a hypothesis on how bacteria will react to different temperatures.
