Agriculturally, plants can be genetically transformed to be resistant to pesticides, spoilage, and frost. In bioremediation bacteria can be transformed to be able to digest oil from oil spills. For medicinal purposes, gene therapy is being used to help people with diseases caused by defective genes. The GFP protein is a green fluorescent protein that is the source for bioluminescent jellyfish. This protein causes the jellyfish to glow in the dark.
Then after agitating the seaweed to remove monosodium glutamate and pouring off the water, 40 mL of distilled water was added to the seaweed and heated. During this procedure, the iodine extract was filtered and several tests, both standard procedure and home- Objective: The purpose of this experiment is to understand how a single substance can be isolated from a mixture, like seaweed and water. Also, learn how to utilize filtration and extraction to make a tincture for testing for Iodine, Iodide Ion, and Triiodide Ion. Procedure: 1. 6 grams of dried seaweed, cut into ½ inches should be places into a 150 mL beakers that will later be filled with ¾ distilled or deionized water.
This allows not only the structure of the neuron to be examined, like the axon and the dendrites, but also any abnormalities to be studied. This is not possible with other staining techniques. Although the Golgi stain was a remarkable breakthrough, it has some limitations. The silver chromate is able to invade some neurons however it does not fill all neurons in an area and stains cells at random. It also provides no internal detail of the cells
At the bottom of the petri dishes we level it with four quadrants to make sure that each of the antibiotics were placed in the right quadrant and be able to see how the bacteria acted in respect to the placement of the antibiotic. One of the quadrants was kept as the control of the experiment. There were six antibiotic but each group obtain only three of the antibiotic for each bacteria. When placing the bacteria on the petri dish we used a pipette to obtain 100uL of the bacteria onto the petri dish. With a rod (spreader) that was dip in ethanol and then place under the busen burner in order to neutralize it; we spread the bacteria on every surface area of the petri dish.
DNA Fingerprinting: Revealing the Truth Name: Zainab Khatoon Due Date: March 19th, 2012 BSC2010L.019S12 Course Name: Biology I Cellular Processes Lab Section: 019 Lab Partner: Hiba Fatima Materials and Methods Restriction Enzyme Digestion Procedure: As with all experiments done in this lab, preparation was accounted for with gloves and goggles. To begin the restriction enzyme digestion procedure, microtest tubes were labeled 1 through 4 for different reactions of restriction enzyme digestion. Then, with the use of the P20 micropipette, ten microliters of Enzyme Reaction Buffer were dispensed into each of the reaction tubes. After the Buffer was dispensed, a fresh micropipette tip replaced the old one. The tip of the micropipette
13. State two observable characteristics that you can use to distinguish an animal cell from a plant cell based on what you saw using the compound light microscope. Show your work. Record the high-power field diameter both in millimetres and micrometres in your table. Skill Practice Part 2 — Estimating Cell
Biological Evidence Darryl Arnold Jr. CJS / 215 Week 2 James Anderson May 1, 2015 What is Biological Evidence and what in the world is it used for? It is safe to say it is used for personnel identification. The collection of this evidence is significant to the scene. The presence of a certain fluid may be of significance in and of itself. This is how scientists and investigators get the necessary DNA to link to a suspect or victim.
So by using case studies it is impossible to generate general laws and principles as only one persons behaviour is examined and can’t be generalised. But using laboratory experiments of large samples of people can generate general laws for behaviour.
These days, it’s not surprising to witness a person being pushed into a large donut-shaped ring like machines for a test. Even complicated neurological disorders are getting identified easily using scanning machines like Computed tomography (also called a CT or CAT scanner) and the Magnetic resonance imaging (MRI) scanner. The advantages of these machines are numerous. This paper will briefly talk about these two methods (CT & MRI) testing, why doctors order the test, how the test is performed, and what kinds of outcomes are expected from the tests. Doctors order CT and MRI scanning tests for different purposes.
Specialised laboratory Within this task I will describe what is required in a specialised laboratory and how these types of equipment will affect the progression of the lab in order for it to work to the best potential. This will explain the types of equipment will fit into this laboratory. Medical Laboratory This is a laboratory which tests are done on clinical specimens in order to get information about the health of a patient as pertaining to the diagnosis, treatment, and prevention of disease. Within this laboratory there are many types of equipment which are used like test tubes, a folin-Wu tube which is used for blood glucose determination, glass slides which are used with microscopes, a Petri dish, glass beakers, glass flasks, Pasteur pipette which is used for aspiration and addition of reagents, graduated pipettes which is again used to aspiration and addition of reagents but it if also it is often of minuscule amounts of the material where it is mainly used in colorimetry. They also use syringes and needles, disposable gloves, tourniquet which is used to cause an artificial venous stasis by applying pressure through this rubber tube.
