Answer the question (1) What is the reasoning why basic dyes stain the bacterial cells? (2) Immersion oil is used on the bright-field microscope to observe bacterial cells. What objective can only be used with the immersion oil?
A uniform magnetic field points directly into your paper (make a sketch). A 7 turn coil of wire with a radius of 14.2 cm lies in the plane of the paper. Over a period of 0.00035 seconds, the field is increased from 0.300 T to 1.10 T. How much emf is induced in the coil while B is changing? A-0.12 volts B- 0.91 volts C-28 volts D- 16,000 volts E- 250 volts Which way is the induced emf (or induced...
5. Why are simple stains able to "stick” to bacteria? Explain the chemical properties of the stain and bacteria surface. 3-Preparation of Bacterial Smears and Simple Stains Introduction Microbial cultures are handled using aseptic technique. Aseptie technique is a set of procedures used to minimize contamination of materials by microorganisms from the environment, and to minimize the spread of cultures around the laboratory. In this experiment, you will be using an inoculating loop to transfer bacteria from a culture tube...

i am writing thesis paper for these question (why do we need data structures? What is the relationship between data structure and algorithm? What data structures have we learned? What are their respective logical and physical / storage structures? What are their advantages and disadvantages? In which cases do they apply to (combined with time complexity analysis)? Please analyze the learned data structure one by one. At least one application example combining data structure and algorithm should be given) i...
QUESTION 1 Why is cotton placed at the bottom of the pipette in which the mixture of products and catalyst is injected? The cotton is not necessary but is already in the pipette The cotton absorbs an unwanted side products of the reaction The cotton is a vapor barrier to keep the fumes of the products in The cotton acts as a filter to remove the solid catalyst from the solution QUESTION 2 reaction The following is an example of...
