DNA Structure Monday‚ 15 April 2013 9:01 AM - DNA = Deoxyribonucleic acid DNA is a double-helix: it has two strands that twist around each other Each strand is made of single units call nucleotides It has a sugar-phosphate backbone Bases join the two strands by hydrogen bonds ○ These bases are cytosine‚ guanine‚ adenine and thymine. - Complementary base pairing is a key idea in genetics: C pairs with G‚ and T pairs with A. - Each strand of DNA can be millions of base pairs in length and is

The effect of Temperature on the Xylem of Tomato Plants Question: How does temperature affect the Xylem in Tomato Plants? Introduction: Throughout this experiment I will be testing the size of the Xylem in Roma tomato plants when exposed to different temperatures. I will be placing six Roma Tomatoes in six different area which will each be in different temperatures. After three weeks of constantly watering the tomato plants with blue dyed water I will cut the plant from the root and examine

An investigation into the effects of temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems‚ for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate

DEPENDENT VARIABLES: • Mass of alcohol burnt CONTROLLED VARIABLES: • The length of the wick coming from the spirit burner • Distance of the wick from the bottom of the aluminium can • Temperature change of the water in the aluminium can • Can used as calorimeter • Mass of water in calorimeter • The room temperature (environment) It is important that the controlled variables are all kept the same because it makes the experiment more reliable and accurate. Ways to ensure that the controls are kept

BUOYANCY PHYSICS Student: Instructor: Criteria : Design Introduction The purpose of this experiment to find the effect of temperature on buoyancy . Backround Information Buoyancy (also known as the buoyant force) is the force exerted on an object that is wholly or partly immersed in a fluid. The symbol for the magnitude of buoyancy is B or FB As a vector it must be stated with both magnitude and direction. Buoyancy acts upward for the kind of situations encountered in everyday experience

experiment‚ water was combined with baking soda. Then the temperature was taken‚ and finally calcium chloride was added‚ which formed a chemical reaction. Our lab question was how does the amount of calcium chloride affect the temperature of the product? We chose our independant variable to be the amount of calcium chloride added to the water/baking soda mixture. We had the dependant variable be the ending temperature. My hypothesis is IF we add more calcium chloride‚ THEN the temperature of the product

Abstract In this lab‚ we tested the effects of temperature on fungal amylase and bacterial amylase (Aspergillus oryzae and Bascillus Licheniformis). We used 4 different temperatures in Celsius 0‚ 23‚ 58‚ and 89 for both fungal and amylase. For 10 minutes‚ every 2 minutes we would use 3 drops of each amylase and mix it with iodine to observe the presence of starch at each temperature. We conducted this experiment for both bacterial and fungal amylase. Results were reached based on the color of the

The effect of temperature on the permeability of cell membranes Introduction For my coursework‚ I intend to assess how temperature affects the plasma membrane of a cell. For this I will use the cell of a beetroot. Background What is a cell membrane? The cell membrane‚ also called the plasma membrane is a semipermeable lipid bilayer which is the surface of all cells that surrounds the cytoplasm. The membrane is called a bilayer as it has a double layer of phospholipids. Within the cell membrane
