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.)

Terese Kruszka Beth Lewis How Advertising Influences Us 1. Calfee made it a point in his advertising that Kelloggs all-bran cereal is high in fiber. With being high in fiber it can reduce the risk of some kinds of cancer. He also used the advertising to inform people on their diet and how it can improve with that particular cereal. An advantage of Kelloggs coming out with high fiber cereal would be more brands would come out with other cereals with other nutrients that our bodies could

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:

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

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.

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
