Experimental Laboratory Report: An investigation into the rate of osmosis Liana Gohery - 98332250 12/12/2014 Word count - ………3000……….. 1. Abstract This study was conducted to investigate the effect of concentration gradients on the rate of osmosis. Osmosis is the cellular transport of water‚ this study was conducted to show the significance of the rate at which this occurs. Dialysis bags were filled with three different concentrations of sucrose solutions and two with water. They were

Name: Abdullah Alghamdi Instructor Course code Date Factory Chicken Farming Factory Chicken Farming is the practice of raising chicken in a confinement at high stocking density. A farm operates as the factory. The main product of this industry is eggs and chicken meat for human consumption. Confinement at this high stocking density is one of the emerging practices aimed at producing the highest output at the lowest cost by relying on scale economics‚ modern machinery‚ biotechnology and global

Bermuda’s Feral Chicken Problem. By Justin M. Corday. One of Bermuda’s most pressing and rapidly escalating animal problems is the emergence of the wild chicken population. The Bermuda Agriculture and Fisheries Department estimate that there are about 30‚000 feral chickens that exist in large and small groups throughout the 22 square miles of the Island. Previous attempts to control the population have not worked and the number is rising. This is a domestic challenge that can no longer

OSMOSIS IN POTATO TISSUES Vanessa Tsao‚ Lovette To‚ Wang Yeyun‚ Zhang Shenjia‚ Alicia Mak Class 101‚ Nanyang Girls’ High School‚ 2 Linden Drive‚ Singapore 288683 ABSTRACT In this project‚ the relationship between the concentration of salt solution and the length of the potato strip that was immersed in it was investigated. Five strips of potato of the same length were placed in different Petri dishes that contained water of different salt concentration. They were left for twenty minutes and the length

is to find out which osmotic environment the eggs are in while sitting in different liquids. There are three different types of environments: hypotonic‚ isotonic‚ and hypertonic. Hypotonic solution causes the cell to swell until it bursts. Hypertonic solution causes the cell to shrink or to lose weight. Isotonic solution doesn’t cause the egg to shrink or swell‚ it keeps the cell the same it’s just in a different environment. The hypothesis for the egg in one-hundred-percent water was that it was

turgid which means it had swollen and became hard. This occurred because of the process called osmosis in which plant cells take up water and they start to swell‚ but the cell wall prevents them from bursting. Evaluation In my opinion the experiment was very successful‚ went according to plan and produced a lot of good results. The timing‚ weighing of the chip before and after the experiment‚ measuring correct amount of salt solution all were correct and made the test very fair. On the other

about freezing points. This lab was designed to show us the freezing point of a pure solvent‚ in comparison to a solvent in a solution with a non-volatile solute. The second goal of the experiment is to teach students about osmosis. In the experiment‚ we got to observe osmosis as well as understand dialysis. Procecure : Part 1. Colligative Properties 1.

artificial cells to the diffusion rate using the phenolphthalein-NaOH agar and the HCl solution. Lab #2 was a model of diffusion and osmosis‚ in which we filled the model cells with different solutions and determined the rate of diffusion. In lab #3‚ the results demonstrated the interactions between selectively permeable membranes‚ water‚ and solutes and how they are important in cellular and organismal functions. In lab #1‚ the results showed the diffusion rate between the certain time period of

Five artificial cells were created‚ each being filled with different concentrated solutions of sucrose. These artificial cells were placed in hypertonic‚ hypotonic‚ or isotonic solutions for a period of 90

able to understand what the poet is trying to reveal to you. Luckily I understood very well what the poet was trying to communicate when I read “egg horror poem”‚ by Laurel Winter. I believe that Winter wanted to make the reader feel as if they were one of the eggs‚ feeling all of the suspenseful emotions that come with being an egg‚ she does this by using imagery words‚ voice‚ and her ideas. This involves making me feel like I am waiting in a carton with my friends‚ waiting for the fridge door to
