Pipette

Methods and materials Cell culture medium Making cell culture medium, requires two processes, this includes the medium that has PSG and other without the PSG. 15 ml of 10% FBS was added into a culture flask with 1.5 ml 100x hippos. The culture flask was filled with DMEM up to 150 ml and this will be the medium without the PSG and this process completed the medium without the PSG. The same procedure was followed for the PSG medium, 1.5 ml of PSG was added and that completed the medium with PSG.…

They were labeled “A”, “B”, “C”, and “D” with masking tape on the strings of the bag. The tubes were then filled with 10 ml of a sucrose solution using a 10 ml pipette pump: A and B with a 1% concentration, C with 10% concentration, and D with 25% concentration. After pushing the excess air out, the open side of the bags were folded approximately 2 cm down and tied with 15 cm pieces of twine. The initial weights…

Introduction The purpose of this experiment was to test whether or not the heart rate of a daphnia was effected by three different solutions being added: alcohol, lactic acid and, caffeine. We determined that when alcohol was added the heart rate would decrease. When lactic acid was added the heart rate would decrease, as well. When caffeine was added the heart rate would increase. We determined that alcohol would slow the heart rate because it is a depressant. Since humans that drink alcohol…

For this assignment, I chose to interview Dr. Stuart McDaniel, an assistant professor at the University of Florida. Since Dr. McDaniel was a child, he loved the outdoors and was always interested in backpacking. He had a specific interest for maps and the distribution of plants. Plants on mountain tops never ceased to amaze him. He received is Bachelors of Science in biology from Oberlin College. In 1994, he moved to Paraguay as a Peace Corps volunteer in the Agroforestry department. After that,…

(intermediate) for each of the antibiotics. The adult mentor of this experiment provided safety goggles, safety gloves, and a lab apron that were worn when handling the bacteria. All bacterial cultures were treated as potential hazards and tubes, pipettes, or other tools that come in contact with bacterial cultures were treated with care, in order to avoid ingesting or inhaling any bacteria. Ethanol also releases harmful vapors, so the experiment was performed in a well-ventilated room with…

These three tests are going to examine…

These rules and instructions for the safety of the person who doing experiments in the laboratory and also others in the laboratory. Because one mistake can do a severe damage to lots of people. Because of that, following rules are very important to follow. [1][2][3] 1. “SAFETY FIRST” is the main thing. Use “COMMON SENSE” to avoid accidents. 2. Working and doing experiments alone in the laboratory is forbidden. 3. Everyone must wear approved safety goggles at all times. 4. Everyone must wear…

Title: How Temperature Affects Protein Detection In Eggs Whites Introduction: Research Objective and Hypothesis The objective of this experiment is to gain a better understanding on how temperature affects how much protein is detected. Understanding how temperature affects the detection of protein can be used to more accurately measure the amount of protein in foods and supplements needed for life. This knowledge can benefit nutritionists and the general population. Hypothesis: If the egg…

periment 1: Determination of Vitamin C Name: Mariam Eskandari Student #: 140856340 Date Conducted: September 8th, 2014 Date Submitted: September 15th, 2014 Partner’s Name: Jessica Macinnis Lab Section: Monday 5:30, L2 IAs Name: Ryan Hiebert ABSTRACT This experiment was conducted to calculate the greatest amount of ascorbic acid throughout a selection of 6 different orange juice samples with the help of individual and class data, since some juices seem to have a higher amount of vitamin C…

General Unknowns Bacterium Vitality en Vida Bacteria play a vital role in our daily lives. It is therefore our right to know the importance of being able to distinguish certain strains of bacteria. With the right knowledge we would be able to come up with a cure for a disease. An identity gives way to knowledge, to better understanding and access to information on how an organism works and how we can prevent its worsening effects or isolate its benefits. Scientists have been trying to…
