Answers to Questions Activity 1: Simulating Dialysis (Simple Diffusion) (pp. 2–4) 9. All solutes except albumin are able to diffuse into the right beaker. Using distilled water in the right beaker and either the 100 MWCO or 200 MWCO membrane will remove urea from the left beaker and leave albumin If the left beaker contains NaCl‚ urea‚ and albumin‚ you can selectively remove urea by dispensing a concentration of NaCl into the right beaker equivalent to that in the left beaker and by using

Aim: To investigate how effect of Detergent Concentration (cont.) has on Membrane permeability of Beetroot cells. Hypothesis: I predict that as detergent concentration increases‚ the solution will become less clear‚ plus mass increases. The increases in mass will indicate that the water potential of the Beetroot cell is lower than that of the surrounding sucrose solution. The Beetroot discs will become flaccid and decrease in mass if the water potential of the surrounding solution is lower than

The change adoption process outlined in the Mechanisms of Diffusion of Innovations theory applies to the movie through Joy accepting Sadness as a valid and useful member of the organization. Joy appears to go through the process twice. The process has five stages of Knowledge‚ Persuasion‚ Decision‚ Implementation‚ and Confirmation. The opening scene of the movie introduced all the emotions or the members of the organization that made up Riley. Immediately‚ Joy processes Knowledge‚ Persuasion and

Examining Diffusion and Osmosis Introduction: Purpose: 1. To simulate and observe the diffusion of solutes and the osmosis of water through a semipermeable membrane through color change and sugar tests. 2. To speculate osmosis occurring in dialysis bags and potato cores by comparing percentage change in masses. Background information: Molecules are always in random‚ constant movement due to their kinetic energy. This causes the molecules of a cell to move around and bump into each other

Mr. Reeves Page 1 Cultural Diffusion in the Ancient World Throughout history‚ cultures have mixed all over the world‚ changing beliefs‚ creating new ones‚ and changing the way people look at the world along with their existence. This can be proven from anything from music to food‚ but is especially prevalent in world religion and the way that every culture sees their god‚ or gods‚ and how they think‚ worship‚ and even obey‚ in similar manners. Even though Hebrew conceptions differed from the rest

Activity Over Different Concentrations and Effects The goals of this experiment were to examine the effectively of enzymes on samples of different enzyme concentrations and substrate concentrations. In addition‚ the experiment tested how effective enzymes are on samples of pH levels and temperature levels. A. Effect of Enzyme Concentration Hypothesis: With half as much enzyme concentration then the reaction rate will be half as much than when the enzyme concentration is equal to the substrate

EXPERIMENT 5 GAS DIFFUSION COEFFICIENT OBJECTIVES: Determine the gas diffusion coefficient of acetone using the established Winkelmann’s method KEYWORDS Diffusivity‚ Gas Diffusion Coefficient‚ Winkelmann’s method OVERVIEW The knowledge of physical and chemical properties of certain materials is important because very often process engineering deal with the transformation and distribution of these materials in bulk. One such property is diffusivity. Mass transfer by diffusion takes place

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
