Excessive alcohol intake has a great impact on the cognitive function of a person. It leads to a person to have a poor cognitive function. Which can be affected the persons perception‚ attention‚ memory‚ motor skills‚ language‚ visual and spatial processing. To some extent‚ study indicates that high level of impulsivity in alcohol consumptions of a person has an effect on the frontal lobe related to their behavioral problem (Lyvers et.al.). Furthermore‚ alcohol intoxication causes disruption of prefrontal

"Do different concentrations of solutions determine the mass of a potato?" Introduction: The way to get the full results of this lab was through the process of osmosis. Osmosis is the movement of water across a membrane into a more concentrated solution to reach an equilibrium. When regarding cells osmosis has three different terms that are used to describe their concentration. The first of these words is isotonic. Cells in an isotonic solution show that the water has no net movement and the amount

the cube decreased‚ the absorption rate increased‚ showing that the smaller cells absorbed more sodium hydroxide than bigger cells. The smaller cells were able to absorb more sodium hydroxide as they have a bigger surface area to volume ratio causing them to act more efficiently than the bigger cells. The smallest cell had a ratio of 1:12 while the biggest cell had a ratio of 1:2‚ leaving a gap of 5:12 causing the bigger cell to act less efficient in absorbing the solution in a period of 10 minutes

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

Resting membrane potentials Definition: Large nerve fibers when not transmitting nerve signals is about 90 millivolt. That is‚ the potential inside the fiber is 90 millivolts more negative than the potential in the extracellular fluid on the outside of the fiber. The Na+-k+ pump also causes large concentration gradients for sodium and potassium across the resting nerve membrane. These gradients are the following: Sodium ( outside): 142 mEq/L Sodium ( inside): 14 mEq/L Potassium ( outside):

What happens? For many reactions involving liquids or gases‚ increasing the concentration of the reactants increases the rate of reaction. In a few cases‚ increasing the concentration of one of the reactants may have little noticeable effect of the rate. These cases are discussed and explained further down this page. Don’t assume that if you double the concentration of one of the reactants that you will double the rate of the reaction. It may happen like that‚ but the relationship may well
