  • World War Ii Vacuum Tubes
    1,137 words
    Since the beginning of the Industrial Revolution, people wanted and needed an easier way of calculating and measuring. Through the dreams of Charles Babbage, the computer was born. These new machines could do any regular math more than twice as fast as any human. Sadly, these ideas were not appreciated until almost one hundred years later. In the 1950 's, the idea of computers was brought up again. This is when people finally started crediting Babbage's work. The technology available now made it...

  • Test Tube Degrees Celsius
    1,267 words
    Enzyme Action: Testing Catalase Activity Enzymes are proteins that serve as catalysts and accelerate chemical reactions in living organisms. Enzymes accomplish this by lowering the energy of activation of the organism it is acting upon, however enzymes will only lower the energy of activation for specific organisms, reducing chaotic chemical reactions. The reaction is carried out in its entirety in the active site of the enzyme. The substrate (organism acted upon), binds itself into the active s...

  • Petri Dishes Bacteria Cells
    1,566 words
    In this lab we observed the growth of bacteria in a conjugation and transformation experiment. We expected the mating plate of the conjunction to grow and the bacteria on the transformation plates to grow also. We also practiced using aseptic techniques to clean the lab benches and to keep the bacteria from being contaminated from outside bacteria. This lab will take a total of 2 days because of the observations that need to be made. The parts of this paper will explain the procedure and the obs...

    Lab Report 1: Separation of Proteins Abstract/Summary: "Proteins account for more than 50 % of the dry weight of most cells, and they are instrumental in almost everything organisms do" (Campbell, 1999). The significance of proteins to the continuation of our biological systems is undeniable, and a study of how to quantify proteins seems an appropriate introduction to our studies of biology. In order to study proteins we must first know how to separate then quantify the amount using basic princi...

  • Stimulating Factors Or Triggers Factors Or Triggers Asthma
    725 words
    Asthma is a condition of the bronchial tubes characterized by episodes of constriction and increased mucous production. A person with asthma has bronchial tubes that are super sensitive to various stimuli, or triggers, that can produce asthma symptom. In other words, asthmatics have special sensitivity that causes their lung tissue to react far more than is should to various stimulating factors or triggers. For this reason, people with asthma are said to have "twitchy airways. " Some symptoms th...

    Barco 1000, 1001, 1500 and 1600. These are a series of 9 " analog convergence projectors that Barco came out with from about 1989 to 1993. All very similar to the Barco 600 chassis, but used 9 " Sony ES focus tubes, called the SD- 146 A. A great picture when properly set up, but Barco drove these tubes quite hard, and sudden tube failures were common. These tubes are hard to find on the used market, and are insanely expensive if purchased new. 64 Khz scan rate, 1000 to 1500 lumens. In around 199...

  • Biology Research In Vitro Fertilization
    2,054 words
    In Vitro Fertilization (IVF), is the procedure whereby human babies are conceived, not in the womb but in a test tube or a Petri dish. This procedure has become one of the greatest developments in the world of medical technology. In Vitro Fertilization has given infertile couples the chance to conceive and bear a child from a full term of pregnancy. Without this procedure, their infertility would render them childless. There are many aspects of the IVF program that have been both praised and cri...

    ... ting smaller fragments that travel longer distances than the single cut or uncut, during electrophoresis. Which in turn proves that segment sizes are proportional to distance migrated. On a standard curve, the distance migrated is used in order to extrapolate the size of the DNA (base pairs). For an undigested or uncut p KAN plasmid it is expected that one fragment will be shown, unless the plasmid has been nicked and then will therefore show three. The size of this fragment should be close ...

  • Rate Of Reaction Bunsen Burner
    2,301 words
    For this investigation I am going to investigate the effect of the concentration of an enzyme, in this case Amylase, on the time taken for the enzyme to fully breakdown the substrate, which in this case is starch. The reason why these two enzymes have to be used is because each enzyme is designed specifically to break down only one substrate as each enzyme is made of a protein that causes it to be a specific shape, in this case the enzyme Amylase can only break down starch to dextrin. I am going...
