Aim To find out how the permeability of a beetroot membrane cell is affected by ethanol. To do this we will investigate different concentrations of alcohol (10-70%) and measure the absorbance using a colorimeter to show us how much juice has leaked out. Hypothesis I predict that as the concentration of ethanol goes up‚ the permeability will increase as the ethanol will slowly dissolve more phospholipids (lipid bilayer) and so more anthocyanin (the beetroot juice) will leak out of the membrane

Alcohol can have many negative impacts on the body‚ which can sometimes be permanent or fatal. It seems that many underage and of age drinkers are not aware of the effects. While drinking‚ people get so caught up in the way it makes them feel that they can sometimes forget what the substance is actually doing to their body. Alcohol is defined as a depressant‚ because it slows the central nervous system down. When the central nervous system is slowed down it can cause a decrease in reaction time

Visual Basic Language History Visual Basic was founded by Alan Cooper who was also known as the father of Visual Basic. Originally‚ it was a simple shell that was nicknamed Tripod. Bill Gates later purchased Tripod and changed the name to Ruby. Ruby added a control box which could be used to add components or widgets. Later‚ in 1991‚ Ruby and Quickbasic came together to form Thunder. Thunder added drag and drop tool capability‚ codeless object GUI creations‚ and event oriented programming. Visual

The main focus of this experiment was to find the relationship between temperature and the enzyme activity of amylase. This was achieved by attaining amylase enzyme‚ starch solution and potassium iodide (determines if enzymes hydrolyses the starch solution)‚ water bath and a hot plate. The temperatures used for this experiment were room temperature‚ 37oC‚ 60oC‚ 80oC‚ and 90oC. The hypothesis developed was that as the temperature increased‚ so will enzyme activity. Therefore‚ the ability of the

If there is any violation between the constraint and the data action‚ the action is aborted by the constraint. In SQL‚ we have the following constraints: NOT NULL - Indicates that a column cannot store NULL value UNIQUE - Ensures that each rows for a column must have a unique value PRIMARY KEY - A combination of a NOT NULL and UNIQUE.
