In order for this experiment to be successful one must follow a certain procedure must be followed. This procedure begins by gathering the following materials, four, seven gram packets of Fleischmann's baker's yeast, for petri dishes, four beakers, three colored light bulbs (red, white, and blue), ¼ a cup of warm water at 100 degrees Fahrenheit (per packet of yeast), 1 teaspoon (tsp) of sugar per yeast sample, a stopwatch, a camera, and a ruler in centimeters. After gathering these materials one

The experimenters put on their protective goggles and started the experiment. The first step was for one participant to put approximately 10 mL of the .1 M HCl solution in the test tube with side arm. Getting the correct 10 mL was not important as long as it was close to it. Then the test tube was placed inside the Erlenmeyer flask to which kept the test tube up right. After this was done the lab participant put together the “Apparatus” which consisted of the test tube with side arm inside the flask

Title: Wet mount Aim: The aim of this experiment is to make a wet mount side and observe the paramecium’s and other microorganisms found in the pond water. Background information/ introduction A technique that is widely used in science biology is wet mounts. Practising this technique helps in order to study slides with specimen under a microscope. In this skill the specimen ejected along with a drop of liquid (e.g. water) and then it is covered with a cover slip. Unlike permanent mount slides

Write out a procedure for what you did that I could hand to a first-year chemistry student to prepare the solutions. Obtain FD&C Blue #1 and using a weigh boat weight out a small sample of the FD&C Blue #1 (<0.0030 g). Quantitatively transfer the weighed out Blue dye into a 50.0 mL volumetric flask. Make sure to rinse all of the blue dye off of the weigh boat with de-ionized water. Fill the flask with de-ionized water until the meniscus is at the 50.0 mL mark. Label this solution A. Using a

A History of Tylenol Tylenol: the early years Tylenol was developed by McNeil Laboratories. It has as its active ingredient a generic compound that can be manufactured by most pharmaceutical companies: acetaminophen. After Johnson & Johnson acquired McNeil in 1959, it began aggressively to advertise the product—to health professionals—as an analgesic that was as effective as aspirin but easier on the stomach. By 1970, sales of Tylenol were growing about 20 to 30 percent annually, with projected
