case was filter paper. Given only large sheets, it was cut into a rectangle with 20 cm length and 10 cm width. Before cutting, though gloves were put on so that skin oil would not stain the filter paper. Also, the filter paper was not laid on the lab table, but on a paper towel. With a pencil, a line was drawn 2 cm from the bottom edge of the paper. Marks were put on the line, 2 cm apart, and labeled with the appropriate cations and the unknowns labeled as U1, U2, and U3. The stationary phases were

Student Guidelines for Writing a Formal Laboratory Report Overview An essential part of science is learning to communicate findings from a scientific investigation. Thus, preparation of a laboratory report in the form of a scientific paper is regarded as an important part of your learning. Formal laboratory reports are typically required in the sciences. A formal laboratory report is utilized either for writing up a given laboratory that you performed or for designing and conducting your

Title: Counting the Number of Yeast Cells in a Suspension using Haemocytometer Objective: To estimate the number of cells of yeast per mm3 in five different dilutions of yeast suspension. Introduction: Biologists often need to count the density of cells in a liquid. “Density of cells” means “the number of cells per unit volume of liquid”. For example, they might want to find out the density of red blood cells in blood plasma, the density of bacteria in milk, or the population of Paramecium sp

RC filter (Resistor Capacitor) which is a circuit that comprises of at least one capacitor and resistor and the circuit must also be driven by a voltage or current source. Understanding this will enable me to demonstrate my knowledge based on this report about Resistor Capacitor Filters. Equipment For the experiment, we were provided with five different types of equipment. The electronic equipment that we used was indeed very essential in order to carry out the experiment. The following equipment

Osmosis Introduction: Tissues are made up of cells that have the same structure and function. In this experiment osmosis will be measured in a piece of tissue. Water potential can be determined by the changes in dimensions of the tissues when it is placed in solutions of different concentrations. Research Question: What is the effect of sucrose solution on potato cells Hypothesis: Osmosis will increase when the solutions are less concentrated with sucrose Variables: Dependant: Osmosis

rt) After viewing our percent yields for Zinc Iodide (which were around 100%), we believe this lab was conducted under the best of conditions and produced more than accurate results. In performing the experiment, the measurements for Zinc Sulfate and Barium Iodide did not deviate from the standard to be measured by more than 0.03g (as was indicated for precision in the lab manual). Each time we went through the centrifuge process, the same centrifuge machine was used. To make sure our boiling

The mode in which the plexus is arranged varies in different subjects. It differs from the brachial plexus in not forming an intricate interlacement, but the several nerves of distribution arise from one or more of the spinal nerves, in the following manner: the first lumbar nerve, frequently supplemented by a twig from the last thoracic, splits into an upper and lower branch; the upper and larger branch divides into the iliohypogastric and ilioinguinal nerves; the lower and smaller branch unites
