The Ionic mechanism and propagation of action potentials. The action potential is the result of a large‚ sudden increase in sodium permeability of the membrane. The resulting rush of sodium ions into the membrane and accumulation of positive charge on its inner surface drives the potential towards Ena. This is followed by repolarisation‚ whereby there is a large increase in the membranes permeability to potassium ions‚ hence the membrane returns to Ek. Explanation of the (ionic) mechanisms underlying

Supporter of affirmative action argue that it is intended not only to compensate for past discrimination‚ but also to level an uneven playing field in which discrimination still exists. What do you think? To what extent do we have a society free from discrimination? What is the impact of affirmative action on society today? What alternatives to affirmative action policies exist? As the movement for equality grew stronger and with more conviction‚ civil rights activists evolved their relatively limited

The first argument that supports Affirmative Action is about correcting the testing gap. According to some studies‚ black and hispanic students score lower as a whole than white students on standardized tests‚ like the SAT. Sandel gives the example of a student who attends a poor public school in the South Bronx scoring a 700 and a student who scored a 700 that went to an elite private school in Upper Manhattan. He says that the 700 SAT score from the student in the South Bronx means more than the

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.

Dewey worked as an educationalist and developed his concept of reflective practice and reflection through experiential learning theories. He concluded in his work that the experience the individual lives through can be described as a dynamic continuum - and that each experience influences the quality of future experiences.

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

Team learning. Hackman (1983) defines team as a social system that consists of at least two members who share responsibility for a team product or service‚ recognize themselves as a group and are recognized as such by others as well. According to Senge (1990‚ p.220)‚ “Team learning is the process of aligning and developing the capacity of a team to create the results its members‚ truly desire. It builds on the discipline of developing shared vision. It also builds on personal mastery‚ for talented

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
