Demonstrating osmosis Introduction The movement of water in and out of a system bounded by a membrane permeable to water‚ but not certain other substances‚ can be inferred by either mass changes or volume changes in that system. It is possible to monitor other changes in physical conditions‚ such as texture. Monitoring mass enables quantification of the changes‚ whereas other changes may only be qualitatively measured.

changed colour from pink to blue. About five minutes later the second red litmus paper in line had also changed from pink to blue. Two days later the entire tube had changed colour from pink to blue‚ thus proving that diffusion had occurred. 4. Using my knowledge of diffusion I can easily state that the change of colour the red litmus paper had (from pink to blue) occurred through the act of diffusion. This was due to the fact that there was a high concentration of ammonium hydroxide on the cotton

Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic

Original Chicken Sandwich Starting out at a new job is not so bad until you have to learn and memorize all the steps and processes. When I began my job at Chick-fil-A‚ I had to quickly learn how to "run boards" or basically how to make the sandwiches that are being ordered. The Original Chicken Sandwich is the most famous and most purchased item in the restaurant‚ so there for I had to make them fast and perfect. The items required for the making of the sandwich are basically the chicken fillet

Boston Chicken Case 1. - Assess Boston Chicken’s business strategy. What are its critical success factors and risks? Boston Chicken’s business strategy comes from a different franchising structure in which BC‚ instead of selling store franchises to multiple franchisees‚ sells franchises to 22 regional area developers across the 60 largest U.S. metropolitan markets. This 22 are developers are committed to open 50 - 100 other stores. Therefore‚ its strategy is focused in rapid growth and reaching

“Pepin debone chicken” In this paper I will be giving you my response to the video “Pepin debone chicken” by Jacques Pepin. I will be discussing my view on Chef Jacques Pepin video on how to debone chicken‚ as well as the benefits of using his technique. In my opinion‚ Chef Jacques video for deboning chicken makes it look far easier than I would have thought. I watched the video several times‚ and no matter how many times I watched it‚ it always intrigues me. I wonder how many chickens Chef Jacques

THE DIGESTIVE SYSTEM OF CHICKEN In most livestock‚ teeth function to grind feed into smaller particles. Birds must pass feed usually whole into the esophagus because they do not have teeth. Therefore‚ particles of poultry feed should be small enough to pass through the esophagus. Feed passes from the mouth and through the precrop esophagus to the crop. If the proventriculus and gizzard are full‚ feed is stored in the crop. Feed is also moistened in the crop. Feed passes from the crop through the

objective of this experiment was to test the effect of a specialized type of diffusion called osmosis‚ “which involves in selective transport of water molecules across a selectively permeable membrane” (Lab Manual 2nd edition). It was hypothesized that osmosis will occur when there is an uneven distribution of solute in a solvent. The more abundant the solute is in solvent‚ the higher the rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal

Measuring Crime CJA/204 October 9‚ 2013 Richard Pacheco Measuring Crime There are two different instruments used in reporting crime. There are also major crimes reporting program used in the United States. These major crime reporting programs do have a purpose and does give statistical information on crime in the United States. There are a difference between crime rates‚ arrest rates‚ clearance rates‚ and recidivism rates. The information reported about crime rates can be misleading and give

Osmosis is the diffusion of water molecules across a semi-permeable membrane. Diffusion is the movement of molecules from an area of high concentration‚ to an area of low concentration. So‚ Osmosis is the movement of water molecules from an area where there are lots of water molecules to an area where there are few water molecules. Our aim is to find the concentration of dissolved substances in the cells of a potato using Osmosis. I predict that the potato in the higher concentration of salt
