This lab was performed to test six different pen inks to determine if they are pure substances or mixtures. This lab also showed how to use chromatography to identify pure substances versus mixtures. By using a filter paper and a petri dish full of solvent, we were able to see the difference between how pure substances and mixtures separate. After performing this lab, it was concluded that three out of six of the pen inks used were pure substances, and the other three were mixtures

Introduction Seed germination is a process in which the plant’s embryo developed from the seed and forms seedling (Bello, Hatterman-Valenti & Owen, 2000). The process of germination starts with imbibition which is the uptake of water by the dry, followed by the activation of enzyme and ends with the elongation of the radicle. The imbibition stage is a crucial process as it is the first event that moves the seed from a dry, quiescent, dormant organism to the resumption of embryo growth (Bewley

The -DNA plate and -DNA/+amp were control plates, no colonies were supposed to grow on these plates because of the -DNA, which occurred. The +DNA/+amp and +DNA/+amp/+IPTG plate were the experiment plates since it had +DNA instead of -DNA. Additionally, the cells on these two plates would transform and the plate would form colonies since they were the experiment plates. The purpose of incubating the cells in ice, then 42oC ice water, then back to ice was because to transform the cells and take in

Cellular Respiration Ben Gipson BIO 1400 Exercise 6.1 Alcoholic fermentation is a metabolic pathway used primarily by yeast and some bacteria. In fermentation, glucose is broken down into ethyl alcohol (ethanol) and carbon dioxide. In the process, some of the energy that had been stored in the glucose bonds is used to form high energy bonds in ATP. Name some factors that affect enzyme activity. Temperature, pH, enzyme concentration, substrate concentration Materials: yeast, test tubes,

BIOL120 Assignment 1: Practical Report THE GERMINATION RESPONSE OF BARLEY AND MAIZE TO TEMPERATURE Practical Report ABSTRACT An experiment was conducted with the aim of observing the temperature required for the optimal germination of barley and maize. Given that barley and maize embryos are known for germinating in autumn and summer respectively it was to be expected that maize would have a higher threshold to temperature than barley. To investigate this, samples of both maize and barley embryos

the new up and coming IPv6. We will use many sources to confirm and relate the information as needed. Global Name Zones provide the user to have static records. It does not support dynamic updates (Petri 2009), and it was to aid the old WINS system that has been around since Windows NT. (Petri 2009) It is more commonly referred as the GNZ in the IT world of acronyms. If the records are not maintained by IT administrators it is not worth having them be GNZ’s. It helps you communicate with trusted

The materials used include gloves, a micropipette, sterile pipette tips, a hot water bath, ice, centrifuge tubes, sterile loops, E. coli colonies, and various petri dishes containing Luria Bertani agar, ampicillin, and arabinose. Before beginning make sure to put on sterile gloves that fit, as they will be required to be worn for the entire lab due to the bacteria being worked with. First obtain two centrifuge tubes, then label them with either your name or initials. One tube will be positive for

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

Animal testing has been around since the 4th and 3rd centuries BCE from the writings of the Greek. They are used for research to develop the understanding of science, to establish more solutions to medical problems, and mainly the protection of people, animals and the environment. Animals are important for research because it allows the scientist to learn more information about human biology and health. With the information gathered, scientist can then develop new medicines. Animal testing is vital
