  • 5 Test Tubes With Deionized Water
    1,640 words
    Detection of Biological Molecules Introduction: Without carbon, nitrogen, hydrogen, sulfur, oxygen and phosphorus, life wouldn't exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds, ionic bonds, hydrogen bonds, and disulfide bonds. Covalent bonds are especially strong, thus, are present in monomers, the building blocks of life. These monomers combine to make polymers, which is a long chain of monomers strung together. Biological mol...
  • Phenol Red Carbohydrate Test

    Enterobacter Aerogenes Identifying bacteria may seem like a daunting task, but if approached slowly and methodically it can be achieved. The objective assigned to each individual in Dr. Robbins microbiology lab was to identify a randomly chosen bacterium. I chose test tube number forty-six. Upon selection, I immediately conducted a gram stain to determine if the unknown was gram negative, gram positive, and find out cell morphology. I discovered that my unknown was a gram-negative bacillus with ...
  • Common Side Effects From Codeine
    328 words
    Effects of Codeine on the Human Body Codeine is mainly used as a pain reliever, but is also used for the relief of a non-productive cough, and as an anti-diarrheal agent. 120 mg of codeine administered SC (subcutaneously, injected under the skin) provides pain relief equal to 10 mg of morphine administered by the same route. Doses used to relieve cough or diarrhea range from 5 mg to 30 mg. Codeine is absorbed quickly from the GI tract and it's first pass through the liver results in very little ...
  • Colour Of The Test Tube Effects
    435 words
    Does the Colour of a Liquid Effect How Fast it Cools? I am trying to find out if the colour of a liquid effects how quickly it cools down. Method: 1. First I took five test tubes and filled each one with 5 ml of black, blue, green, red and 'clear' colouring (for the 'clear' colouring I simply used water.) 2. I then filled each of the test tubes with 25 ml of boiling (of course whilst wearing safety goggles.) water and waited for the temperature to fall to 50^0 C and then measured the temperature...

  • Iodine And The Benedicts Test

    Salivary Amylase Lab In this laboratory, I observed the process by which salivary amylase, an enzyme secreted by the salivary glands in the mouth, breaks starch down into maltose. This requires a relatively straightforward experiment with only a couple of indicators, some test tubes, and a starch source. To understand the process, one has to understand chemical reactions with enzymes and the its major role in the digestive system of the human (Chapter 37). Just to refresh the reader, I will defi...

    In the province of the mind, what one believes to be true either is true or becomes true. -John Lilly The assignment required me to assess the possible outcome of the Barnum Effect on people by means of performing a simple experiment entitled The Person-Tree Test. The test was relatively simple: I looked for a participant, and given a pencil and a sheet of paper, I allowed my participant to freely draw a person and a tree, saying that the said drawing will more or less reflect his personality. U...
  • More Acidic Condition
    243 words
    Analysis From my results I could see that the amylase seemed to break down the starch at a quicker rate when it was in a more acidic condition. When we tested it in an alkaline condition it didn't manage to break down the starch in the hour that we had available. From my graph it is clear that the more acidic the buffer solution the quicker the starch was broken down by the amylase. The graph showed a positive correlation as the length of the reaction increased due to the more alkaline condition...

    Statistics are often used to describe and interpret the results of intelligence testing. After gathering data using descriptive, correlation, or experimental research methods, we organize, summarize, and make inferences from that data using statistics. To summarize the data, we use the three measures of central tendency: The simplest measure is the mode, the most frequently occurring score. The most common reported is the mean, or arithmetic average (the total sum of all the scores divided by th...
