Introduction The cognitive difference between people who regularly abuse alcohol and those who drink socially has been explored using a range of investigatory paradigms. One of the approaches used was the emotional Stroop paradigm (Williams et al.‚ 1996). When the word meaning and ink color are different the color naming is found to be slower than when the semantic content of a word is neutral. This slowing is known as the Stroop effect‚ from which it is concluded that an attentional bias has developed

Alcohol abuse is increasing in our society especially among the younger generation‚ this issue has many causes and effects. For example‚ peer group people emotional‚ social and family issues. Unfortunately‚ the person doing the drinking is not the only one who feels the impact of this abuse. It has a profound and direct impact on their families as well as their friends and acquaintances. When you are an alcoholic‚ even though you may not notice the changes‚ everyone else around you will. It may

Alcohol Dependence‚ also known as alcoholism‚ is a very widespread disabling addictive disorder‚ affecting 4% of Canadians. Alcoholism may start innocuously‚ due to the acceptability of social drinking‚ but over time‚ can lead to serious health problems‚ including brain‚ kidney and liver damage. Although alcoholics seem to be doing the most damage to themselves‚ they are hurting their families even more. Lesser-known‚ but just as serious victims of alcohol abuse are the alcoholics’ children. The

Beet Cell Lab Purpose: The purpose of this Lab was to see how much pressure or stress the beet tissue would hold. Hypothesis: I hypothesize that the higher % of the solvent that the higher the colour intensity will be shown on the ph colour scale. The lower the solvent then the less colour shown. Materials: *Test Tubes (4) *Cork Borer *Beets *Water *1% Acetone *50% Acetone *1% Methanol *50% Methanol Procedure: *Cut 4 uniform cylinders of beet using a cork borer with a 5-mm

of Beet Root Sarah Hsu Y 11 Hope Purpose The beetroot experiment is to investigate and understand the affect different temperatures have on cell membrane structures. Hypothesis The higher the temperature is‚ the higher the rate of absorbance of the cell membrane will be. Variables Controlled Variables | Independent Variables | Dependent Variables | The length of the beetroot placed into the test tube. | The temperature of the water bath. | The absorbance of the cell membrane of

Planning Aim In this experiment I will be testing the effect of temperature on the plasma membrane of a beetroot. I will do this by measuring the percentage light transmission using a spectrophotometer. Once I have obtained my results‚ I will justify them using scientific knowledge explaining what I have observed whilst carrying out the experiment. Factors to be controlled "« The pH concentration "« Regular use of distilled water "« Ensuring that the surface area of each piece of beetroot is

Investigating the Effect of Temperature on the Permeability of Membranes The permeability of membranes can be altered in several ways. From previous preliminary work I know that reagents‚ for example detergents and alcohol alter the arrangement of the phospholipids in the membrane allowing substances to leak out of the cell. Temperature also affects the membrane. As membranes relay on protein molecules to allow molecules to enter and leave the cell through facilitated diffusion the temperature must

Effects of Temperature on Beetroot Cell Membranes Background Information: A cell membranes is a thin structure that surrounds the whole cell. It contains the cytoplasm of a cell. The cell membrane is made up of hydrophilic region and a hydrophobic region. The hydrophilic region likes water‚ it is on the outside of the cell‚ the hydrophobic region is the inside of the cell where its protected from H2O. The cell membrane’s outer surface lets larger molecules into the cell. The inner surface deals

The effects of Alcohol on the Human Body Name: Institution: Introduction Today‚ alcohol is one of the most common substances that people abuse. It is an addictive drink that has become a popular way of having a good time or relaxing in social gatherings. It is among the most commonly used psychoactive drugs. Alcohol is a popular social phenomenon‚ yet most societies forget its effects on their bodies. Research has carried out in the recent years on the effects that alcohol consumption is having
