Mixing Alcohol and Energy Drinks In recent years the consumption of energy drinks combined with alcohol has become popular for young adults in North America. Energy drinks are caffeinated beverages that intend to provide a burst of energy and/or enhance alertness. The principle active ingredients in energy drinks are caffeine‚ high doses of sugar (or a sugar substitute)‚ they generally include B vitamins‚ an amino acid‚ and plant/herbal extracts. Alcohol is a highly addictive and most commonly

Experiment 2 The Cell Membrane Abstract The boundary between any cell and its environment is the plasma membrane‚ composed of a matrix of phospholipid molecules along with a number of different kinds of proteins. Membranes have different properties and a variety of functions‚ in large part determined by the specific proteins within the membrane. This experiment is designed to determine the stress that various factors‚ such as osmotic balance‚ detergents and pH‚ have on biological membranes. There are three

chemistry‚ an alcohol is an organic compound in which the hydroxyl functional group (-OH) is bound to a carbon atom. In particular‚ this carbon center should be saturated‚ having single bonds to three other atoms.[1] An important class of alcohols are the simple acyclic alcohols‚ the general formula for which is CnH2n+1OH. Of those‚ ethanol (C2H5OH) is the type of alcohol found in alcoholic beverages‚ and in common speech the word alcohol refers specifically to ethanol. Other alcohols are usually

Alcohol and Fetal Alcohol Syndrome Alcohol plays a major role in society today. It is constantly being . ...... in our minds through advertisements‚ whether its commercials or billboards‚ holidays‚ or even just at the popular social scene. Alcohol is consumed for many purposes‚ such as celebrations‚ to increase romance‚ out of boredom‚ or a way to relax. Alcohol is a drug that is depended upon by the majority of our society. Nonetheless‚ alcohol has very damaging effects‚ not only

Plan:- Independent Variable- Temperature is what I will be changing in the experiment. I want to find out what effect temperature has on the permeability of a cell membrane. Controlling other Variables- I will use measures to ensure that everything stays the same in my test to gain the best and most reliable results possible - Same volume of water that I put the beetroot into after heating. - The beetroot I use will be the same size each time‚ I will ensure this using a cork borer. - The beetroot

twentieth century‚ little was known about cell membranes. Until the early 1950s‚ the biological cell membrane was rarely mentioned in scientific literature. It was recognised that something was probably there‚ but hardly anything about it was known. Considering the lack of technical equipment available a century ago‚ scientists such as Charles Overton and Edwin Gorter were not only exploring new territory in looking at the properties of cell membranes‚ but laying the way for future cell biologists

How much alcohol do teens use? Alcohol is the most frequently used drug by teenagers in the United States. About half of junior high and senior high school students drink alcohol on a monthly basis‚ and 14% of teens have been intoxicated at least once in the past year. Nearly 8% of teens who drink say they drink at least five or more alcoholic drinks in a row (binge drink). What are the dangerous effects of alcohol use in teens? Just a few of the many dangerous effects of alcohol use in teens

Purpose: The purpose of this lab is to test the effects of osmosis on eggs in hypertonic solutions and hypotonic solutions. Hypothesis: If the corn syrup is a hypertonic solution‚ then the egg’s size will shrink. If the water is a hypotonic solution‚ then the egg will swell. Materials: Styrofoam cups (2 per group) Styrofoam cups to weigh down egg (2) Balance Paper towels Vinegar (enough to cover egg) Distilled water Corn syrup Fresh eggs (2 per group) Procedure: Day
