Homework Answers
1. ANSWER - c.
EXPLANATION - E. coli is a mesophile. It have the ability to live in between 20°C to 45°C. Therefore, at 4°C, no growth will occur. So, the graph will be a straight line.
2. ANSWER - b.
EXPLANATION - Phsychrotrophs best grown betwenn the temperature of 0–15 °C. So, Listeria monocytogenes have the ability to tolerate the temperature of 4 °C . So, the graph is b.
3. ANSWER - a.
EXPLANATION - The bacterium is isolated from deep ocean floor. It is a phsychrophilic bacteria. It is adapted to grow in between 2–4 °C . Therefore, it will grow under 4 °C . So, the graph will exponential (a).

The growth rate of Escherichia coli, a common bacterium found in the human intestine
Growth of Bacteria The growth rate of Escherichia coli, a common bacterium found in the human intestine, is proportional to its size. Under ideal laboratory conditions, when this bacterium is grown in a nutrient broth medium, the number of cells in a culture doubles approximately every 20 min. (a) If the initial population is 20, determine the function Q(t) that expresses the growth of the number of cells of this bacterium as a function of time t (in minutes). (b) How long would...

4.) Among the following six statements given below which two best account for the results obtained by the researchers who produced Figure 1? 1. Low glucose conditions caused mutations that made individual E. coli cells better suited to these conditions 2. Daughter cells acquired the ability to tolerate low-glucose conditions as they received enzymes and membrane components that had been modified by their mother cell. 3. The initial E. coli population may have included some cells whose genes favored their...

Part A Which of the following statements accurately describes bacterial cell walls? In bacteria with acid-tast cell walls, the carboxylic acid in the walls forms a layer outside a thin layer of hydrophilic polypeptides. The cell walls of gram-negative bacteria contain many more layers of peptidoglycan than those of gram-positive bacteria. In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an outer membrane made of phospholipids, lipopolysaccharides, and proteins Gram-negative bacterial cell walls contain teichoic acids, whereas the...

32. Study the signaling pathway illustrated below, which involves two different receptors. Assume that a protein is active only when it is activated, but not inhibited, by its upstream signaling molecules. Activation and inhibition are indicated by normal and blunt arrows, respectively. Assume that the transcription regulator can be activated by either the binding protein or the kinase that are immediately upstream of the transcription factor. Under which of the following conditions will the expression of target:gene "X" be induced?...
