Lab Report DIFFUSION AND THE EFFECT OF AMYLASE. Aim: We will interpret and explain the activity of an enzyme added to a solution. We will analyze reactions in different pH ranges. The starch solution will appear blue when mixed with iodine. But after mixing the enzyme amylase to the starch‚ the starches are broken down into simple sugars. Now‚ when the iodine is added‚ no color change exist. Instruments and materials used: 1.) Dialysis bags x2 2.)

Response to “The Human Cost of an illiterate society” 1/30/2011 In “The Human cost of an illiterate society‚” Jonathan Kozol attempts to convince his reader that illiteracy is extremely harmful to a society‚ and that it is the ultimate destruction of a human being’s life. He explains with great detail how being ignorant

Factors Affecting Diffusion How does temperature affect diffusion? What is Diffusion? Definition 1: Diffusion is a process where by molecules move from an area of high concentration area to an area of low concentration. Definition 2: Diffusion is an evidence for moving particles. The spreading out of a gas is called diffusion and it takes place in haphazard and random way. Gases diffuse because the particles collide with other particles and bounce of in all directions. For example when

DIFFUSION REVIEW WORKSHEET 1. Define diffusion and what causes it to occur? The action of spreading the light from a light source evenly so as to reduce glare and harsh shadows. Diffusion is caused when entities are small and moving in molecules. They collide because they are moving at a random pace. The temperature causes diffusion. 2. Define the terms hypertonic‚ hypotonic‚ and isotonic solution. * Hypertonic: Having increased pressure or tone‚ in particular. * Hypotonic:

Précis: In "The Human Cost of an Illiterate Society"‚ Jonathan Kozol‚ a Harvard graduate‚ argues that illiteracy cause the loss of choice or freedom and leads to many problems. Kozol highlights his argument with examples of when illiteracy can be binding such as "Many illiterates cannot read the admonition on a pack of cigarettes. Neither the Surgeon General’s warning nor its reproduction on the package can alert them to the risks."(20). He gives extensive and detailed scenarios in order to raise

differences. We used PhysioEx software to examine diffusion. In these experiments we used different sized membranes as well as NaCl‚ urea‚ glucose‚ albumin‚ powdered charcoal‚ and KCl. The step by step process was used by the software so that we could see the different kinds of reactions. According to the data found‚ we found that with high molecular weight compounds are too large to penetrate the molecular weight cut off pores and no simple diffusion can occur. So it seemed like the easiest way for

Chiquita‚ great work on the discussion‚ you highlighted the impact and struggles experienced by GM over the years on the American society and the world to be exact since they are a multinational organization. I am in agreement that even though the company has gone through difficult times they are still among the top in the industry throughout the world. Personally what gives great confidence as an investor in GM is the fact that they have gone through difficulties and manage to rebound time and

The Human Cost of an Illiterate Society By Jonathan Kozol Main Idea: The negative affects illiterate people have on themselves‚ their family and society. Supporting Details: Illiterate people often do not understand the bills they receive and are not able to write the checks to pay them. They often are in the situation of signing documents that they do not understand (230). Illiterate citizens very seldom vote. They are not able make informed decisions based on serious printed information
