How does the relationship between salt concentration effect osmosis in the aquatic plant Elodea? Quantitative data From observing the cells under a microscope‚ we see that they are continuously moving and therefore are alive. We have observed that when the cells are in the 10% sodium chloride‚ the chloroplasts are positioned to the sides of the cell wall and the cytoplasm is more expanded. Cells in the distilled water are slightly smaller than the cells in the sodium chloride solution and

Solution for Chapter 2 Exercise 5a 5. a. Draw the hierarchy chart and then plan the logic for a program for the sales manager of The Couch Potato Furniture Company. The manager needs a program to determine the profit on any item sold. Input includes the wholesale price and retail price for an item. The output is the item’s profit‚ which is the retail price minus the wholesale price. Use three modules. The main program declares global variables and calls housekeeping‚ detail‚ and end-of-job

An investigation to compare the reaction rates between potato and hydrogen peroxide against liver and hydrogen peroxide through loss in mass. Background information: Catalase is an enzyme that is found in all cells. This means that it is an intracellular enzyme. And enzyme is a biological catalyst. A catalyst is some thing that speeds up a reaction without being changed itself. Because of this enzymes and catalysts can be used again and again. Enzymes are protein chains that have a primary‚ secondary

TITLE: EFFECT OF DEEP FAT FRYING ON OIL QUALITY AND SENSORY ATTRIBUTES OF POTATO CHIPS/ CHICKEN NUGGETS ABSTRACT: RBD Palm olein oil is a type of vegetable oils with the ratio of saturation to unsaturation 40%: 60%. Soybean oil is another type of vegetable oils with the ratio of saturation to unsaturation 20%: 80%. In addition to the chemical alterations that occur during frying‚ changes in the oil’s physical and thermal properties‚ such as surface tension‚ viscosity‚ density‚ specific

Concentration ·Enzyme Concentration The factor I am changing is surface area of potato containing Catalase. By increasing the surface area of the potato‚ you make more Catalase molecules be exposed to hydrogen peroxide. This will result in the rate of reaction increasing because it increases the chance of more successful collisions between the enzyme and the substrate. Catalase is an enzyme found in food such as‚ potato. It is used to break down a poisonous by-product of metabolism called hydrogen

Introduction The movement of molecules from an area of greater concentration to an area of less concentration is called Diffusion. Osmosis is the diffusion of water through a selectively permeable membrane from an area with greater concentration of water to an area with less concentration. A Hypertonic Solution is a solution of a higher concentration of solutes and a smaller concentration of water molecules than another solution. However‚ an Isotonic Solution is a solution that contains an equal

and sweet potato peelings as chicken feed supplement on the growth of the chick. More than 50 billion chickens are reared annually as a source of food for both their meat and their eggs. Chickens farmed for meat are called broilers‚ whilst these farmed for eggs are called egg-laying hens. In total‚ UK alone consumes over 29 million eggs per day. Some hens can produce over 300 eggs a year. The majority of poultry are raised using intensive

change in weight of potato tubers‚ this was conducted in order to explore the process of diffusion and osmosis and more importantly to investigate the question of “Does different concentrations of sucrose solutions have an effect on the final weight for the potato tubers?” In this experiment we estimated the osmolarity of potato tuber cores by submersing different potato cores into sucrose solutions of 0.0-0.6M‚ and weighing the potato. The results showed the weight of the potato tubers had the highest
