    Diffusion and Osmosis Lab Introduction • What molecules can pass through a semi-permeable membrane? In this lab study we tested carbohydrates such as starch and glucose‚ as well as solutions like Benedict’s and Lugol’s to see if they would cross the membrane of a cell but since we can’t actually see that happen we used dialysis tubing (acts as the cell membrane). • My prediction was that glucose and Benedict’s could pass the semi-permeable membrane but starch and Lugol’s wouldn’t be able to

    Laboratory Report on Urine Examination Introduction: When testing urine the test results may provide information regarding the status of carbohydrate metabolism and kidney function. The kidney glomeruli act as ultrafilters for the plasma protein; however as much as 150 mg/dl of protein may normally be excreted into the urine. In glomerular proteinuria‚ an increase in glomerular permeability occurs‚ resulting in an increase of urine proteins. High urine protein concentration therefore may indicate

    Comparison Paper on the Book Iliad and Film Troy   On the Plot The plot of the book and the film has a very big difference especially on its coverage and focus. The coverage of the film starts all the way from why the Trojan-Greeks conflict started up to the death of Achilles and the fall of Troy. While on the other hand‚ the book’ onset is narrowed down to the ninth year of the Trojan war wherein the conflict between Achilles and Agamemnon is intensified. Aside from this the book ends

The cells in the solutions of distilled water‚ 0.4% NaCl‚ and 0.9% NaCl would all appear to be inflated and could burst. This is due to the fact that the solution is hypotonic to the potato‚ thus water is entering the cell. Meanwhile‚ the cells in the solutions

    Osmosis and the Egg Lab Report  By: N. Mullins  Date: January 20‚ 2011    Introduction  This lab was designed to explain the different things osmosis does. Osmosis is the  diffusion of water across a semi permeable membrane. Over three days we tested the egg  in three different solutions to observe the changes. On Day 1‚ the main question we  answered was what happened to the egg when it was placed in vinegar? Before doing this  I came to my hypothesis was that the vinegar would eat away at the shell and eventually

    Osmosis is the selective diffusion of water and other molecules across membranes‚ which in the case of living organisms‚ the solvent (water) would have net movement across a selective permeable membrane. Osmosis only occurs when a membrane such as that of a cell is permeable to water molecules but not to specific solutes (Tortora & Derrickson 2014). Certain simple molecules such as oxygen‚ water and carbon dioxide can travel across the cell membrane by osmosis‚ a passive process similar to other

    the beaker of water for a longer period of time‚ then more water will travel through the selectively permeable membrane due to the effects of diffusion on the solution. If the level of sucrose within the solution increases‚ then the effects of osmosis will cause the change in mass to also increase due to higher concentrations of sucrose and the increased net movement of the water molecules within the solution. Analysis - When the glucose and starch solution was placed in the beaker of water for

    My First Lab Report: Diffusion and Osmosis To begin‚ this is my first time doing an experiment and a lab report for biology’s class. Although‚ it was a little hard at the beginning‚ my team and I got the hang of it and we finished it on time. It was actually kind of fun. There were three steps in the experiment: 3.1 A – Molecular Movement: In this session‚ I was observing a sample and determining if there was a movement or not. 3.1B –Diffusion through semi-permeable membrane dialysis tube: In this
