Blood Lab Report Introduction A blood experiment was performed testing four different patients blood to find out their specific blood types. Blood types are categorized in four blood groups based upon the antigen ( proteins on the surface of blood cells that can cause a response from the immune system) ("Rh factor" 2006) on the surface of the red blood cell. The blood groups are A‚ B‚ AB and O‚ names which are broken down from the ABO blood group system. Although simulated blood was used

Bacteria‚ such as Vibrio natriegens‚ are single cellular‚ microscopic microorganisms. Bacteria grow by cell division‚ mainly by a process called binary fission‚ where two cells arise from one single cell (Madigan et al.‚ 2015). In bacteria such as Vibrio natriegens‚ who are curved-rod shaped microorganisms‚ they elongate to almost twice their own size and form a dividing wall in which splits the single cell into two daughter cells (Madigan et al.‚ 2015). There are four phases to bacterial cell growth:

Observing Aluminum Foil Lab Alexandra Bellissimo Mrs. Taylor D1P4 Date preformed: September 11th 2014 Date of Submission: September 19th 2014 The purpose of this experiment is to calculate the thickness of aluminum foil in centimeters. In this lab we measured the thickness by plugging in the quantitative properties of our piece of aluminum foil into the equation for volume and then isolated “h” to solve for height. The thinking behind this method is that by using

Introduction The purpose of this lab is to be able to observe the reaction rates of different chemical substances‚ by looking at which substance is the fastest reactant. This is what chemical kinetics is. Reaction rate is the change in the concentration of a reactant or product in a chemical reaction per unit time. In this lab the requirement was to be able to calculate each Average reaction rate which is the change in reactant or product concentration at a given time interval. Some equations that

Nick Work October 20‚ 3013 CSI: Intro to Biology Blood Sampling Objective Our Objective is to identify which blood type each sample is. We test Anti-A and Anti – B‚ and also test to determine if it is Rh positive or negative. Hypothesis We are testing unknown blood sample testing for what type of blood. When A is shown in the blood sample agglutination will accrue causing it to look grainy. Materials At least 4 dropper vial 3 blood samples Synthetic Anti – A Synthetic Anti –B Synthetic

Introduction The purpose to this lab was to isolate and identify two unknown bacteria from a mixed culture provided to us by our instructor. This study was done by applying all of the methods that have been instructed on thus far in microbiology laboratory class. Each test performed‚ provided us with some key information about the unknown microbes in question and how the bacteria function. Materials and Methods Over a two week period‚ eight prepared types of test media were provided to

During the experiment‚ we made observations and possible explanations on why Copper(II)Chloride Dehydrate and Aluminum foil created a chemical reaction. The observations were made by using Copper Chloride‚ Aluminum foil‚ and Distilled water. Before the Aluminum

Coccus is a term used to describe a type of morphology that helps us distinguish different kinds of bacteria. The cell’s morphology is only one of the many ways we can differentiate the different species. Looking at these bacterium underneath the microscope is an important step to determine which kind of species it is. All cocci bacteria are not gram positive‚ but this lab will examine only this kind because of their influence in human health. Staphylococcus Aureus is a gram-positive coccus bacterium

Bacteria Lab Write-Up Jianna Liu P8 Purpose: The purpose of this lab is to find out which substance‚ alcohol‚ antibacterial soap‚ water‚ or hydrogen peroxide‚ is the best at preventing the growth of bacteria. Hypothesis: Antibacterial soap will be the best because soap is a substance that people use to wash their hands because it takes away the germs. Even the name‚ antibacterial soap‚ suggests that it fights off bacteria. Hydrogen peroxide is second because it is used

The purpose of the unknown bacteria lab assignment was to select an unknown bacteria culture and‚ through a series of metabolic tests‚ identify which bacteria genus resided in the pure culture received. A nutrient broth inoculated with bacterial culture (numbered 45‚ henceforth referenced as U45) was selected and a streak plate was made to isolate a pure culture for use throughout the assignment. From the streak plate‚ several slides were made to determine the morphology of unknown 45. A Gram stain
