AHP216 04/16/13 I. Introduction: The purpose of this experiment is to observe the osmosis reaction in a potato with salt and water. In cooking cooks will soak their cut potato’s in water if they will not use them immediately. This allows the potato’s to be used later without turning color. The experiment shows the flow of water through the membranes of the potato with salt over a period of four hours. II. Objective: The reaction of the potato to the side submerged in water and the half excavated

Diffusion and Osmosis Introduction Tonicity refers to the concentration of solutes in a solution (Lab 6-7). There are three stages of tonicity: Isotonic‚ hypertonic and hypotonic. Four unknown solutions were given and labeled as followed: Solution A‚ Solution B‚ Solution C‚ and Solution D. Since potato cells were used for this type of experiment‚ in an Isotonic solution the solute and water concentration are the same as inside the cell in which the isotonic solution contains 0.9% NaCl. In other

Osmosis Lab Report by Evan Gerber Claire Cambron First Lab Report Wednesday 10:30am February 20‚ 2013 Theresa Gburek Abstract The major objective of the experiment was to test the effect of the concentration gradient on the diffusion rate. It was hypothesized that the greater the stronger the concentration gradient‚ the faster the rate of diffusion would be. To test this‚ dialysis tubes were submerged in different concentration fructose solutions. We weighed the tubes at specific

The Development Of the Egg and Sperm your name PSY/265 May 20‚ 2012 Nicole Pansey The sperm and the egg are the key to reproduction. Without the sperm fertilizing the egg there would no reproduction. They both start off in very different places and in different ways but come together to create a life. The journey to create a life is a very interesting one and in this paper I will be outlining it in detail‚ describing the male and female sex organs and the role of both these

Sperm and Egg Donation Many children will never know anything about their biological background‚ because their mother had a sperm or egg donation. Is that fair to children because their mother made that choice? Everybody deserves to know where they came from‚ and what risks they could suffer in life. For example heart disease‚ Parkinson’s disease‚ degenerative diseases‚ these are just some of the common diseases that could be genetic. Some offspring’s may just want to know their culture and history

The Floating Egg Problem Introduction: This experiment was constructed to aid in the practice of using the volumetric system and the glassware that determines volume. Volumetric glassware contains an accurate amount of liquid and also measures the volume accurately. Density is a measure of how much matter takes up a certain amount of space or volume. The more matter you can pack into a certain space‚ the denser it is. Although we often confused the two‚ density and weight are actually two

In order for your life to be great you must first learn to appreciate it. This theme reflects in the fables “The Goose That Laid the Golden Egg”‚ by Nicky Grischotti and “The Dog and His Reflection”‚ by Tony Payne they both show that you should appreciate what you have and to not be greedy for more. In “The Goose That Laid the Golden Egg”‚ the theme‚ don’t be greedy and appreciate what you have‚ is shown from beginning to the end. For instance‚ Atticus Greeb‚ the main character‚ inherits a large
