1. a. The action potential changes the membrane potential from -70 mV (resting) to +30 mV and back again to the resting membrane potential. b. This results from a change in membrane permeability first to Na then to K due to the opening of what type of ion channels? Voltage gated channels 2. a. Where is the density of voltage-gated Na+ channels the greatest? Axon hillock b. What areas of the neuron generate signals that open these voltage-gated channels? Dendrites and the cell body c.

Assignment 01 ENN103F Question 1 Yes I would say it is morally defensible. Although affirmative action programs can be attacked on strictly legal grounds‚ they are far more defensible on moral and practical grounds‚ and if they are carefully designed‚ even their legality can be defended. The fact that current defenders of legal color-blindness so often have a history of condoning preference as long as it benefited white men shows that they argue in bad faith. The presence of such a powerful and

The action potential is started when the membrane is very slightly ‘depolarised’‚ meaning that the charges inside and outside the cell become more similar. This happens when a stimulus causes a small influx of sodium ions into the cell. For an action potential to occur‚ the voltage has to pass a threshold value of -58mV. at this point‚ in a cycle of positive feedback‚ the action potential will always occur. Once the threshold value has been

Affirmative Action In the Human Rights Act‚ Chapter 214 of the revised statutes‚ 1989‚ it states that "in recognition that human rights must be protected by the rule of law‚ this Legislature affirms the principal that every person is free and equal in dignity and rights without regard to race‚ religion‚ religious creed‚ colour‚ sex‚ physical or mental disability or ethnic or national origin."

Defense of Affirmative Action Affirmative action has been the subject of increasing debate and tension in American society. However‚ the debate over affirmative action has become ensnared in rhetoric that pits equality of opportunity against the equality of results. The debate has been more emotional than intellectual‚ and has generated more tension than shed light on the issue. Participants in the debate have over examined the ethical and moral issues that affirmative action raises while forgetting

There are many forms of industrial action such as: strike Where workers refuse to work for the employer‚ a strike is a collective withdrawal of labour by employees.

Race-based affirmative action is justifiable in order to increase diversity. While many adversaries criticize the notion that there is a collective responsibility of society to make up for past wrong-doings‚ this argument focuses only on promoting diversity. In colleges‚ having a diverse‚ mixed student body allows students to learn from a wide range of backgrounds. It also helps disadvantaged minorities reach higher leadership positions which would then help the general populations of those minorities
