Questions 1 Often, upon doing a negative pom doing a negative stain of unencapsulated Gram-negative cells, a small halo will be seen around the cells. Why is this the case? What external structure of Gram-negative cell will acude the negative stain? 2 What are the functions of a bacterial capsule? 3 Does a species produce a capsule under all conditions of cultivation? Explain. 4 Why is the size of a bacterium more accurate for a negative stain than a direct...
1. There are other staining procedures beyond simple staining and differential staining. Examples include endospore, acid-fast, capsule, and flagella stains. Please pick one staining technique to research and answer the following questions: • What is the theory behind the staining technique, what stains are used, how are they applied, what portion of the bacteria are they reacting with • How is this stain used to differentiate or identify bacterial cells or cell structures? • Describe the staining technique. List and...
Which method of staining is most commonly used, especially in the hospital setting? A) acid fast staining B) gram staining C) simple staining D) vino staining

QUESTIONS 1) Are acid fast cells gram positive or gram negative? Explain why it might be difficult to determine the Gram reaction of acid fast cells. 2) What is the significance of the mycolic acid layer in the following contexts? A) To bacteria for survival and infection B) During the acid fast staining procedure QUESTIONS 1) What is the difference between a pure culture and a pure colony?

What is meant by the term time value of money? - Why is the net present value method superior to other methods such as the payback and simple rate of return methods?
Exercise 8 - Gram Staining Procedure for gram staining. Know all chemicals/reagents used in correct order, function of each chemical, the effect of cach chemical and how gram + and gram - bacteria would appear at each step Color reactions at each step of procedure. Know why, based on the differences in cell wall structure, that the gram + vs gram - bacteria stain either purple or pink. What washes off in the decolorizing step of a gram - bacteria?...
What is meant by the term "operating leverage"? Is high operating leverage a positive or negative position?
