Effect of pH on Enzyme Activity Athenaa Jeyachandran Mr.Menes Course Code January 21st‚ 2013 The Effect on Enzyme Activity Due to Temperatures Purpose: The purpose of this lab experiment is to examine how different temperatures affect enzyme activity using hydrogen peroxide. Hypothesis: My hypothesis for this experiment is that temperatures near body temperature is when enzyme activity will be at its highest. I believe this will occur because in our body‚ enzymes

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

The Tipping point: how little things can make a big difference by Malcom Gladwell is a novel that reveals how ideas‚ messages‚ products‚ and behaviors spread‚ which is explained through three rules heavily influence the Tipping Point and are required for one to consider a scenario as the Tipping Point. The Tipping Point is described as the moment of critical mass‚ the threshold or boiling point that results in change (Gladwell‚ 2000‚ p.12). To explain the Tipping Point Gladwell informs the reader

Introduction Specific heat is defined as the measure of the ability of a substance to change temperature. Specific heat of a substance is the heat needed to change the temperature of 1 gram of a substance once degree Celsius. The more Joules (unit of heat) needed‚ the higher the specific heat will be. The goal is to determine specific heat of a soil sample as compared to water. This difference has many ramifications regarding our climate‚ with local and global. Hypothesis I predict that after

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
