Osmosis investigation Aim: To investigate how sugar concentration affects the mass or size of a potato and find out the sugar solution. Introduction: Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low water concentration until the concentration on both sides is equal. This means that osmosis is like diffusion involving water molecules. Osmosis occurs across a partially permeable membrane‚ with holes

can be anywhere from 15-29 pounds‚ but if you found a badger in the fall‚ it would probably weigh around 33-37 pounds. Badgers are scientifically considered carnivores‚ and they eat earthworms‚ large insects‚ small mammals‚ carrion‚ cereals and root tubers. European badgers live to be up to 14 years‚ and they stay with their families for most of‚ if not all of‚ their lives. A badger’s life is started by being born into a litter of roughly 5 cubs during the springtime‚ then nursed for 4 months. Defense:

This report will be specifically be looking at only the potato chip snack industry and will be observing other competing products with same features. Additionally‚ no other snack industries will be discussed in this report; such as‚ apples‚ pies and cakes etc. When observing the snack market‚ potato chips can form a market

Introduction This practical experiment was performed in an attempt to observe how enzymes (starch phosphorylase in particular) are affected by varying its temperature before introducing it to the substrate it will be reacting with. A catalyst (enzyme) is a substance that changes the rate of a reaction; for a reaction to take place at all‚ the enzyme must first come into contact with the substrate. Enzymes are subject to a number of factors which effect how fast they can cause a reaction with a substrate;

flowed into or out of the potato. Hypothesis: Our hypothesis was “If the sucrose levels in the water are high‚ then the osmosis will occur at a less frequent rate. However‚ if the concentration of the solution is less than that of the potato (like in distilled water)‚ then the mass of the potato will increase.” Independent and Dependent Variable: The independent variable in this lab was the sucrose concentration. The dependent variable in this lab was the mass of the potato slice. Control Group

the cell sap in the potato tissue. I can make this conclusion because the results show a big increase in weight of the potato piece. Meaning that water has moved from outside the potato into the potato due to Osmosis‚ proving that the distilled water had a higher concentration of water‚ as water moves from a high concentration to a low concentration. I can also see that the glucose solution of 0.8M has a much lower water concentration then the cell sap in the potato tissue. I know
