Introduction Molecules are constantly in motion due to thermal energy. Therefore‚ the molecules will move around and bump into each other. Because of this‚ molecules tend to spread out evenly into available space in a process called diffusion. Diffusion is the random process of molecules moving from areas of high concentration to low concentration‚ thus requiring no energy. Many of the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement

Osmosis and Water Potential Year 11 Emary Venter INTRODUCTION: The cell is the basic unit of living things‚ and is made up of multiple organelles. Organelles are membrane bound subdivisions‚ each specialised for a specific function. This experiment looks at the Plasma Membrane‚ which is a semipermeable layer surrounding the cell. It’s primary job is to control what goes in and out of the cell. Molecules can move across this membrane in either an active movement or a passive movement

POTENTIAL EFFECTS OF DISCRIMINATION. TASK 3: In looking at this task‚ we have already studied the first part of the topic at the beginning of the Unit. Forms of Discriminatory Practice exist‚ in the form of: Prejudice‚ Stereotyping‚ Labelling‚ Bullying‚ Abuse‚ Lack of choice‚ Infringement of Rights‚ and Covert/Overt abuse of Power. Do we accept that these forms of discrimination exist? What do you think……as maybe you do not agree? Discrimination can be understood as damaging the individual

the question is a series of related business issues. The underlying themes typically include the following: Market demand - "How many dollars are there in this market for our product?" Market potential - "How much of the potential in the market can we capture?" (Tipp 2001). This paper attempts to estimate the market demand and potential of Personal Digitial Assistant (PDAs) in a defined geographic market of the State of Maryland.

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):
