Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

Identification of Unknown Carbohydrates using various biochemical tests Date of experiment: 11/10/2012 Name of Student: Vicki Marshall Introduction A series of biochemical tests was carried out to identify unknown carbohydrates. There were six carbohydrates that needed to be identified; they have been randomly labelled A-F. The carbohydrates are glucose‚ fructose‚ maltose‚ lactose‚ sucrose and starch. There was six tests that were carried out to help identify them‚ these were: Iodine Test

Difference between Good Carbohydrates vs Bad Carbohydrates Which one do you prefer‚ French fries or a tomato and spinach salad? These two types of food are carbohydrates‚ however the second option contains good carbs (vegetables.) Carbohydrates (carbs) are very essential in the body‚ nutrionists recommend that 60% of our everyday intake should come from carbohydrates. Carbohydrates are classified into: Sugar: This is a simple carbohydrate. Some sugars are natural while others are added to your

Introduction: With the execution of this experiment‚ we began to go deeper into the Cell and Molecular Biology course. The main focus of the experiment would be how the Restriction Endonucleases cleave the strands of DNA. For this experiment‚ pBR322 was the specimen to use. Restriction Endonucleases work by cleaving the sugar phosphate backbone of specific DNA sites. Restriction enzymes that have been isolated from bacteria have a defensive role. This idea is illustrated when an attacking foreign

Low Carbohydrate Diets VS Low Fat Diets Concerning weight loss‚ there are countless varieties of diets‚ swearing to be the most effective‚ innovative‚ easiest‚ and fastest‚ leaving us confused; running down a path of failure to loosing the weight permanently. Unfortunately‚ loosing weight is a challenge‚ but the opportunity of success is much closer than you think. No matter what type of diet you are on‚ it is important to know that diets usually make you go on a program that is either low carbohydrate

dentifying the classes of Biomolecules The Introduction A Biomolecule is any molecule that is in the human body. There are four major biomolecules‚ they are Carbohydrates‚ Lipids‚ Proteins‚ and Nucleic Acids and they all have different functions and characteristics to classify an organism. Carbohydrates are the most important source of energy for your body‚ this is mainly sugar. Lipids are molecules that contain hydrocarbons and make up the structure and function of living cells. Nucleic acids

Saliva Lab Since the amylase enzyme is present in saliva‚ starch digestion begins in the mouth. Salivary amylase changes the polysaccharide starch into many disaccharide molecules of maltase (a simple sugar) which are further broken down into glucose units by maltase enzyme in the As stated above‚ saliva contains the amylase enzyme which begins the breakdown of starches. The efficiency of starch digestion by amylase can be measured by how much simple sugar it produces under
