Null hypothesis The concentration of sucrose in the soil will not affect the growth of the common wheat seeds. Alternative hypothesis The concentration of sucrose in the soil will affect by slowing down the growth of the common wheat (Triticum aestivum) seeds. The sucrose solution (sucrose mixed with water) added to the soil makes high concentration outside the common wheat cells and the common wheat cells become an area of low concentration. Because the osmosis is reversed‚ the

observe how molarity concentration affects diffusion.The lab was primarily based on osmosis and diffusion. Diffusion is when the movement of molecules from a high concentration that go to a low concentration to a high concentration to eventually reach an equilibrium. Osmosis is when water will diffuse from high water concentration to low water concentration to reach equilibrium. When the solutions are different the lower concentration solute is hypotonic while the higher concentration solute is hypertonic

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. Because of the selective permeability of the membrane only water and other very small particles (iodine) can be diffused through simple diffusion. The solution out of the dialysis tubing had a higher distelled iodine concentration of solutes (iodine + H2O) than did the starch solution. So iodine move into the cell and react with starch molecules to formed starchiodine‚ the blue compound

“The first essential for the child’s development is concentration. It lays the whole basis for his character and social behavior‚ he must find out how to concentrate‚ and for this he needs things to concentrate upon…” The Absorbent Mind‚ Chapter 22 Discuss how the Montessori Education helps to develop a child’s concentration and helps the child in his social development. In order to accomplish any task you need to be able to concentrate

investigation how sugar solutions of different concentrations affect osmosis. Research Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution to one of a higher concentration. If a solution has a low concentration then the amount of (in the case of my investigation) sugar‚ the solute‚ will be low and the solution will be weak. If there is high amount of sugar then the solution will be concentrated (have a high concentration). When two solutions are divided

An investigation into the effects of sugar concentration on yeast activity Introduction: Yeasts are eukaryotic micro organisms belonging to the kingdom fungi. Yeasts live on sugars and produce ethanol and carbon dioxide as by-products. [James Mallory‚ 1984]When Yeasts are given water and sucrose they convert the sucrose into glucose then convert the glucose into carbon dioxide and ethanol following the following reaction: C₆H₁₂O₆ ( 2(C₂H₅OH + CO₂ [Brady Burkhart‚ Terrell Grayson and Eric Kimler

What happens? For many reactions involving liquids or gases‚ increasing the concentration of the reactants increases the rate of reaction. In a few cases‚ increasing the concentration of one of the reactants may have little noticeable effect of the rate. These cases are discussed and explained further down this page. Don’t assume that if you double the concentration of one of the reactants that you will double the rate of the reaction. It may happen like that‚ but the relationship may well

ruthless place for Jews in concentration camps. A large number of people who got put into concentration camps died either from being gassed or being worked to death. The bodies of those Jews would either be cremated or buried in mass graves‚ or not even buried at all. Hitler thought that the loss of WWI was the Jews fault‚ thus Hitler started the mass murder and Genocide of all Jewish people in Germany and Central Europe. There were approximately 20‚000 German concentration camps for WWII. There were

Discuss the effects of increased concentration in transport markets. Concentration ratio refers to the market share of the largest firms in an industry. For example‚ a 5 firm concentration ratio of 65% means that the 5 largest firms have more 65% of market sales. If the concentration ratio increased‚ then 1 or 2 firms may start to dominate the market and the firms will be able to exercise Monopoly power. (in UK legal definition of a monopoly is a firm with more than 25%) This is likely to cause many
