Study guide for Microbiology Chapter 2
Name________________
1. List and describe the sequence steps routinely used to identify bacteria. These are referred to as the “five I’s” in your text.
2. Define / describe each of the following as they apply to microbiology: a. Culture f. pure culture b. Inoculum g. contaminated culture c. Inoculation h. mixed culture d. Colony
3. Microbiologists employee a number of approached to acquiring a pure culture from a from sample containing a number of different types of bacteria. Briefly describe three different procedures commonly used to secure pure cultures from a mixed culture. The use of simple labeled diagrams may be quite helpful.

acute pain-a protective mechanism that alerts the individual to a condition or experiece that is immediately harmful
There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes, such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics. The experiment was done by applying methods in order to identify an unknown bacterium.
1. Some people accuse sociologists of observing conditions that are obvious. How does looking at sociology as “making the familiar strange” help counter this claim? How does sociology differ from simple commonsense reasoning?
Morality is based off the individual and underlining factors. One book cannot determine how one should live, believes secular humanist. Right and wrong is based on the opinion of the individual, the environment, and circumstance. The Bible gives us the Ten Commandments to help on stay on a straight path. I agree that environment and circumstances have an influence on behavior but not on whether the behavior is right or wrong. (71)
In his book “Start With Why,” Simon Sinek describes the difference between leaders that inspire and those who simply delegate; he encourages readers to look at leadership with a new outlook, and he motivates people to act upon his vision: start with ‘WHY’ instead of ‘HOW.’ He supports his advice with anecdotes of events inspired by real people like Martin Luther King Jr., Steve Jobs, and the Write Brothers. He realized that these individuals all had similar leadership techniques, which happen to be the exact opposite of what other, less successful, leaders do. Sinek calls his formula “The Golden Circle” (Sinek, P.37), which provides insight for how people can be inspired, movements can be prompted, and organizations established. Upon finishing his book, I conclude that Sinek is onto something with his theory; in order to be an extraordinary leader, one must start within.

2) Record the shape of the bacteria, the arrangement of the bacteria, and the gram staining characteristics.
A Dichotomous Key was studied to identify bacteria and their relationships. Some of the organisms at the end of the Dichotomous Key had viable characteristics that separate them from different groups, and those that did not students learned how to further classify them. A Dichotomous Key is used to narrow down the search for the unknown organism tested. It is organized by phenotypic characteristics of organisms and conducts a systematic way of identifying the other unknowns. In the lab students were given a tube labeled with a number. Instructions were given to conduct a Gram stain to begin the search followed by the use of a Dichotomous Key and photos as resources to carry out the search. Instructions read to isolate and identify the unknown bacterium with both differential and selective tests to positively identify the given unknown organism. Differential tests used specifically for this unknown microorganism was BEA (Bile Esculin Agar), which interpreted results by the hydrolysis of esculin when the media is blackened around
Summarize and give an example for either the Cosmological or Teleological Proof for God’s existence.

The twenty-story Carson Building is constructed of concrete blocks. Each and every concrete block in the structure can withstand an earthquake of 9.5 on the Richter scale. Therefore, the building can withstand an earthquake of 9.5 on the Richter scale.
Use the distributive property to remove the parentheses in the following expression. Then simplify your result if possible.
Describe in details the four ways in which bacteria increase their genetic diversity. (10 points)
