RESTING POTENTIAL Resting potential is the membrane potential when a neuron is not conducting any electrical impulse or signal. The resting potential is around -75 mV. During resting potential‚ the inside of the axon is negative GRADED POTENTIAL ACTION POTENTIAL Action potential is a fleeting reversal of the membrane potential‚ caused by changes in permeability of the plasma membrane of neuron to potassium and sodium ions causing an electrical impulse to be transmitted along the axon.

1. Gather information from secondary sources (including photos/diagrams/models) to observe‚ analyse and compare the structure of vertebrate forelimbs. Comparative anatomy is the study of the differences and similarities in structure between different organisms. An example of comparative anatomy is the pentadactyl limb which is the basic five-digit bone structure of many vertebrate’s forelimbs. The vertebrate forelimb (or the pentadactyl limb) comprises of the humerus (upper arm)‚ radius and ulna

BIOL 3810-504 Compound Action Potentials Date Performed: 15FEB2011 Date Due: 01MAR2011 Introduction Neurons are the cells that receive and transmit electrical signals (University of North Texas‚ 2010). The ability of the neuron to conduct these impulses is because of an electrochemical voltage across the plasma membrane of that neuron. An action potential is an all or nothing response to a stimulus along a single axon. A compound action potential is a graded response that results from

ADDRESSING BARRIERS TO LEARNING Introduction Access to education is a human right but all over South Africa‚ in rural and urban areas‚ learners experience barriers to learning. Some barriers may differ greatly and some not at all but the main result is that they hinder each learner from reaching their full academic potential. Teachers need to look at the barriers within their classrooms and schools and find ways to overcome them in order to get the best out of their learners. Ways to address

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

NON TARIFF BARRIERS What are non tariff barriers? Non- tariff barriers are broadly defined as any impediment to trade other than tariffs. Non tariff barriers can be classified into two groups; Direct and Indirect. (a)Direct Barriers are barriers that specifically limit import of goods or services. Eg: Embargoes and quotas EMBARGOES: Embargoes are the most restrictive of the direct non tariff barriers. They are either a complete ban on trade with a foreign nation or a ban on sales or transfer

Key Term and Why I am Interested in it I picked Tariff Barriers as my topic. The reason behind this decision was for what a Tariff Barrier is designed to do. It protects a respective country’s businesses from foreign competition. Key Term Tariff Barriers‚ also known as Import Restraints‚ limit the amount of goods or products that can be imported into a particular country. They are a form of taxes that are designed to prevent goods from foreign competitors to be circulated within that country.

hit the united states in the 1980’s‚ and it hit with a fury. Recently‚ an infant is believed to be cured of HIV‚ using high dosage antiretroviral (ARV) drugs within hours after being born. This paper points out the extraordinary achievement of a potential ‘cure’ for HIV. This close examination of the treatment and proper procedure that was implemented‚ can possibly point out the very steps that are needed to duplicate this procedure.
