Identifying Unknown Bacteria Using Biochemical and Molecular Methods Beginning of Instructor Pages Instructor Pages - - 3 Purpose The purpose of this lab is to introduce a variety of lab techniques to students working on the common problem of identifying an unknown bacterium. This lab helps students develop an understanding of the biochemical and molecular differences in bacteria and introduces the concept of identifying species based on characeristic gene sequences. Students work through

important in identification of a genus and species of bacteria are biological tests‚ including the determination of the types of nutrients a cell can use‚ the products of its metabolism‚ and the response to specific chemicals. Other factors that can assist in identification of bacteria are their ecological habitats and more advanced methods such as genetic and molecular composition. Using various techniques one is able to distinguish and ultimately assign then genus and species of the unknown bacteria

1. Title: Double unknown identification of a mixed culture of Gram-negative and Gram-positive bacteria 2. Author: Nick Fiore‚ University of Kansas‚ Biology 402‚ Fall 2014 3:00pm room 6040 3. Abstract: The purpose of this experiment was to isolate two unknown bacteria and perform a series of selective and differential tests to correctly identify each. After the bacteria was isolated a series of differential and selective tests following the dichotomous key attached were used to identify each bacteria

The Fear of The Unknown The short stories of Ben Loory‚ Stories for Nighttime and Some for the Day‚ exhibit numerous postmodern qualities through literary context‚ language and themes. One of these reoccurring themes within the collection is the concept of fear of the unknown. Three stories exemplary of this theme are “The Magic Pig‚” “The Fish in the Teapot‚” and “The Snake in the Throat.” In every one of these stories chosen there is an appearance of an object.

The fallibility of Eyewitness Identification and Testimony INTRODUCTION: Eyewitness identification and testimonies are relied on heavily by the criminal justice system to help with investigation and prosecution of crimes and criminals. Due to the increase in the use of eyewitness identification psychologist began studying the results more efficiently to gain a clearer understanding of the risks it holds.. A scientific literature on this specific topic was created and highlighted the issues that

RESOURCE IDENTIFICATION Resource Identification Resource Identification Learning is a process that can be difficult or easy‚ depending on two main variables; the student and the available resources. These resources determine the learning curve of the student. Even if the student is intelligent and the learning tools are not sufficient‚ things may become difficult. Students should be able to get help whenever a difficult situation arrives. Easy access to these tools is key component for

"The Unknown Citizen" is an occasional poem. That is to say‚ it is a poem written to mark a specific occasion or event. The occasion is indicated in the lines contained in parenthesis that precede the body of the poem. As these lines indicate‚ the poem is a written monument that functions like a cenotaph: it commemorates a fallen man whose identity is unknown. However‚ unlike the soldier who falls in a battle of war‚ the battle this individual appears to be unwittingly a part of is a social battle

any specific mineral. Well‚ “because the atomic structure of a mineral species is always the same‚ most of its physical properties are relatively constant and may be used for the mineral’s identification” (Gardiner and Wilcox 107). There are many intriguing physical properties to mineral identification. Visible properties include color‚ luster‚ streak‚ crystal form‚ cleavage. The tactile property can be measured using Mohs scale‚ which measures hardness of minerals compared to common objects

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

1. Your Herbarium collection should consist of: • At least 8 weed mounted specimens‚ each specimen with a complete label. A standard artists Sketch Book approximately 37 x 27 cm (or A3) has suitable pages on which to mount specimens. Mounting of specimens may be done with good quality tape (archival 3M)‚ water-soluble glue such as PVA wood glue or sewing using dental tape. • Your specimens should include: 8 specimens (min.) of declared weeds. • All material should be ideally in a reproductive
