Session #1 Lab 1 OBSERVING BACTERIA AND BLOOD D Haynes BIO-218A Microbiology Lab Friday‚ January 17‚ 5:00pm Objective(s): Our objective is to gain knowledge of the functions and operations of the microscope through observation of bacteria and blood slides that are available for this assignment. We are also learning to “see” and observe various bacteria and their shapes as well as live yogurt cultures‚ blood‚ plaque and cheek swab samples and their arrangements. We

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

The center hole through the ferrule is large enough to fit the Fiber cladding (which is usually 125um after fiber coating stripped off) but tight enough to hold the fiber in a fixed position without any further moving. Standard bore diameters are 126 +1/-0 um for single mode connectors and 127 +2/-0 um for multimode connectors. Because of fiber cladding diameter’s variation from manufacturing‚ some fiber

concentration of the absorbing species‚ . When this information is graphed with absorbance on the y axis and at different points of concentration on the x axis‚ the best fit line equation will have a slope that is equal to Ԑ‚ giving us molar absorptivity (1). Then we can use the value of Ԑ to determine the concentration of [K2Cr2O7]‚ by taking the absorbance ratings and dividing them by Ԑ. Determining the order of reaction for a reactant‚ in this case K2Cr2O7‚ must be done experimentally (2). This is

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Unit 1 Lab 2 Grit Test Eric Mendoza (14689887) I guess according the test I am a extremely “Gritty” individual. It states that I am grittier than 80% of the American Populous. I guess I can attribute that to my military experiences. I will now do my do diligence in answering the question on the lab sheet. Question 1) what difference does age has in your ability to be persistent? I think age has nothing to do with being determined or persistent. It is an inherent trait that is taught

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise
