Action potential to occur in a neuron. This will be achieved by firstly‚ defining the purpose of neurons in the body along with a description of the components within a neuron and how they enable information to be passed through the cell membrane and on to other neurons. Secondly‚ the resting potential of a neuron will be explored with relation to the concept of selective permeability and the purpose of the Sodium - Potassium pump. Thirdly‚ the molecular basis of the Action Potential will be

How does Absence of Food Affect Time Crickets Spend Resting? Samer Aldaher BIO 2490 Behavior Section Dr. David Gilley INTRODUCTION: What happens to crickets in phases of food insufficiency? In particular‚ how does their resting behavior change‚ if it even changes at all? The reason behind this study was to find out whether crickets applied their resting behavior as a means to survive or conserve energy in times of “famine”‚ if you will. During the preliminary time spent noting and describing

IMPULSE CONTROL DISORDERS Many of the self-control disorders involve disturbances in the ability to regulate an impulse - an urge to act. People with impulse control disorders act on certain impulses involving some potentially harmful behavior that they cannot resist. Impulsive behavior in and of itself is not necessarily harmful; in fact‚ we all act impulsively upon occasion. Usually our impulsive acts have no ill effects‚ but in some instances they may involve risk. Consider the following

by using the application of membrane have become highly demand in various industries. In this newly separation process ‚ the membrane function as a semi-permeable barrier and the separation process occur by the membrane controlling the rate of movement of various molecules between two liquid phases ‚ two gas phases or a mixture of a gas phase and liquid phase. In industries‚ many companies have high demand on both quality and quantity of water for production. Membrane process can be used to separate

Part 1 Part 1 of the experiment investigated the effect of different temperatures on beetroot cell membranes (a type of plant cell). Through this experiment‚ the process of diffusion and osmosis was in action. Various temperatures ranging from low temperatures to high temperatures such as -5⁰C‚ 5⁰C‚ 30⁰C‚ 50⁰C and 80⁰C were used to investigate the temperature effects on beetroot cell membranes. The hypothesis predicted that the higher the temperature the darker the beetroot substance and the lower

Title Membrane Permeability Aim To determine the effect of various chemicals and high temperature on the membrane permeability of beetroot Hypothesis Organic solvent and high temperature will destroy the cell membrane and make it permeable to the red pigment. The higher the concentration of the alcohol‚ the greater will be this effect. Principle Beetroot is the material used in this experiment to demonstrate the effects of high temperature and chemicals on the permeability of the cell membranes

Impulse control disorders are conditions in which the afflicted cannot control his or her actions. Examples of Impulse control disorders include Pyromania and Kleptomania‚ the uncontrollable urge to set fire to something and the urge to steal something usually invaluable for the sheer rush of stealing‚ respectively. Both these disorders sound like excuses to illegal activities but studies show that only 5% of shoplifters can be diagnosed with Kleptomania and less that 2% of people accused of arson
