on human samples collected from different body sites. The tests are used to detect and identify any microorganisms capable of causing disease. Knowing of unknown microorganism is important on how this microorganism works and how it is structured‚ means knowing how it can affect humans. The purpose of this study was to identify an unknown bacterium by applying all methods that were previously conducted and learned in the medical microbiology laboratory class. **Materials

What is the difference between hypothesis and law? A hypothesis is a statement‚ put forth on the basis of reasoning‚ about the things that are being studied. A hypothesis is an educated guess based on past scientific studies and previous experiments. It is not just a random guess. Observation is followed by a hypothesis. For example ‘Plants need sunlight to grow’ can be a hypothesis. It is formulated by taking into account all the observations that are know about the phenomenon under investigation

There is always a problem in an organization that must be resolved. There are many different types of decision making processes that an organization can use to help resolve these problems. This paper will examine some of the different types of decision making processes with examples from four organizations. This includes the decision making processes strengths and weaknesses‚ as well as comparing and contrasting them with each other. This paper will also describe how a problem can best be identified

instrumental for the RNA World Hypothesis ("Sidney Altman: The RNA World"). This hypothesis stated that early life started with RNA as they possess the ability to serve as a catalyst as well as contain genetic information. The RNA was able to spontaneously form under natural processes‚ which eventually replicated into all sorts of life. This paper will analyze the theoretical and experimental support for this hypothesis and comment on the plausibility of the RNA World Hypothesis. The RNA World theory is

A researcher thinks that if expectant mothers use vitamin pills‚ the birth weight of the babies will increase. The average birth weight of the population is 3.0kg. b. An engineer hypothesizes that the mean number of defects can be decreased in a manufacturing process of compact disks by using robots instead of humans

Analysis of an Unknown Mixture Performed: 2/13/14 Submitted: 3/3/14 Abstract: The purpose of this experiment was to separate and identify the two unknown compounds. The sample used was 105 and it contain 2-propanol and 2-heptanone. IR spectrums were taken of the contents of the second and sixth test tubes and showed the presence of an OH functional group and a small amount of ketone in test tube two and a large presence of ketone in test tube six. The average boiling points of the test tubes
