Elena Mesa Nov. 15‚ 2013 Ms. Lelacheur IB Biology HL The Effect of Temperature on Beet Root Membranes What is the affect of temperature on beetroot membranes? Hypothesis: It is hypothesized that as the temperature increases‚ the deeper red the beetroot water will be. At higher temperatures the proteins in the beetroot plasma membrane will denature‚ leaving holes in the membrane and allowing the red pigment in the cell sap to seep out into the water around it. Variables: Dependent-The

Cheyenne Kenny September 29‚ 2014. Biology Properties Of Water Adhesion How does temperature change affect surface tension? As the temperature of a liquid increases‚ its surface tension decreases. When water heats up‚ the movement of its molecules disrupts the imbalanced forces on the surface of the water and weakens its sheet-like barrier of tightly bound molecules‚ thereby lowering the surface tension. This is why hot water is more effective when cleaning; its low surface

Introduction: In this experiment I aim to investigate the effect of the surface area to volume ratio on the rate evaporation of water in different sized containers. By measuring the time it takes for the whole amount of water to evaporate‚ a conclusion can be made about the validity of the surface to volume ratio in regards to the biological process of diffusion. Research Question: What is the effect of the surface area to volume ratio on the evaporation of water? Variables: - Independent:

Effect of Temperature on Peroxidase Ability to Break Down H2O2 By: Rodneika Crutcher Abstract Temperature affects the ability of peroxidase to break down hydrogen peroxide. In this experiment our professor extracted peroxidase from potato tissue. In order to determine how temperature affects peroxidase we created solutions and measured their absorbance levels after water bath treatments. The more absorbent the solution was the less hydrogen peroxide there was in the solution. This means the peroxidase

Heat release rate of a subway car on fire in a shrink-scale model Abstract: Heat release rate in a shrink-scale model of a subway car on fire is measured for various aspects of an ignition source and simulated materials differing in material by using shrink scale model. The time is required to reach the value‚ although the maximum Heat Release Rate value is independent of the position of the ignition source. The best method for determining the heat release rate is the maximum Heat Release Rate

Breakdown of the asset. While gas ovens can differ from model to model‚ they operate on similar principles. First lets explain how a typical gas oven operates and which problems may occur. A gas oven ignition system consists of three basic components; the oven controls‚ the igniter and the oven safety valve. In newer models the igniter will be a glow igniter‚ or in ovens that are a few years old‚ an electrical igniter. Old ovens may work with a pilot light igniter. In this breakdown we will

1. Temperature: Put some hot water‚ warm water‚ and cold water in three bowls. Just use water from your faucet‚ and please be sure that the hot water is not too hot to touch! Place a finger in the hot water and a finger of the other hand in the cold water. After a few seconds‚ place them both in the warm water. Describe the sensations. Can you trust your senses for measuring temperature? Explain your answer. Placing finger A(pointing finger on left hand) in the “hot” water‚ my finger felt a hot

On Saturday‚ December 2nd‚ I saw the Live Newspaper Production of: BOILING POINT! Water‚ Politics‚ and Power. Boiling Point is production directed by Tom Harryman that gave a voice‚ while using satire‚ to show the flaws of how people of power in America deal with problems revolved around water. In this essay‚ I will analyze the audience‚ design‚ theme‚ acting‚ and the spectacle of the play. The audience had a mixed group of people. Even though I did not see anyone under that age of 17‚ I heard a
