Name: Marion Paxton Diffusion Lab Introduction: In this lab you will observe the diffusion of a substance across a semi permeable membrane. Iodine is a known indicator for starch. An indicator is a substance that chances color in the presence of the substance it indicates. Watch as your teacher demonstrates how iodine changes in the presence of starch. **Prelab Observations: Describe what happened when iodine came into contact with starch. The cornstarch turned blue-black Procedure:

Evidence for and against the Davson – Danielli model of the membrane structure Analysis of evidence from electron microscopy that led to the proposal of the Davson-Danielli model 1. A lighter area sandwiched in between two darker layers 2. Proteins appear dark in electron micrographs and phospholids appear light. This appearance supports the Davson-Danielli model. 3. Proteins stain darkly‚ suggesting that the dark pattern of the cytoplasm of the red blood cell is the distribution of proteins 4

Abstract The article describes a technique for processing liquid radioactive waste water using membrane techniques to single out only radioactive waste components without affecting the salt ballast. This solution dramatically reduces the amount of radioactive concentrates to be long-term storage‚ and provides an opportunity to re-use treated water and chemicals. Keywords. Liquid radioactive waste‚ radioactive waste water purification‚ reverse osmosis‚ selective extraction of radionuclides. Introduction

investigation I will be measuring the effects of temperature on the membrane permeability of beetroot. I will be measuring the amount of anthocyanin that will diffuse out of the beetroot. The way in which I will measure the anthocyanin is to check the light absorbency of the solution using a colorimeter. The higher the reading on colorimeter the more anthocyanin present in the solution To find out the permeability of the beetroot membrane I will firstly cut out cylinders of beetroot using a cork borer

Investigating the effects of temperature on cell membranes Independent variable: Temperature of beetroot Dependent variable: Absorbency of light Hypothesis: As temperature rises to its optimum temperature‚ the absorbency of light will increase because protein is an enzyme and will therefore be affected by temperature. This is because more beetroot dye will pass through the cell membrane and then into the distilled water. The deeper the colour of the beetroot dye‚ the higher the absorbency

Materials & Methods Brook trout blood was used throughout our experiment as our erythrocyte suspension‚ which consisted of ten drops of fish blood in a test tube containing 10mL of 0.7% NaCl. Eleven other solutions‚ (erythritol‚ xylose‚ monacetin‚ diacetin‚ triacetin‚ urea‚ thiourea‚ glycerol‚ ethylene glycol‚ glucose and fructose) all isosmotic but not necessarily isotonic with the cytoplasm of the erythrocyte‚ were combined with a 0.2mL of well-mixed stock suspension were added to 0.27M of each

to be; however‚ with a closer look one can see that all explanations have the same message. Science and the Bible‚ often considered polar opposites‚ tell the same story just with different words. For instance‚ Genesis One and The World’s Biggest Membrane describe an ongoing process of creation. It is clear in Genesis One that God did not get it right the first time. After creating man God thinks‚ “It is not good for the man to be alone. I will make a helper suitable for him.” (2:18-19) Immediately
