Affirmative Action: Fisher v The University of Texas Affirmative Action. For many Texas high school students‚ these two words haunt them. Their future‚ or at least their future at the University of Texas‚ depends on these words. For Abigail Noel Fisher‚ a 2008 graduate from Sugar Land‚ Texas‚ affirmative action and its race bias policies allegedly ruined her chances of getting into this prestigious state university. Fisher argues that race should not be a factor in college admissions processes

In the 196o’s a policy that created jobs‚ promotions‚ government contracts‚ admission to school and other benefits to minority groups and women. This policy was named Affirmative Action. Affirmative action goes back when discrimination was against african americans‚ native americans‚ hispanics‚ and women‚so to protect their rights‚ it was created. The federal government required for both states and local governments to have this programs. The policy also had to be followed by organizations and

The Effects of Temperature on the Extracellular Firing Rate of Action Potentials in the Ventral Nerve Cord of the Periplaneta Americana Andrew Goldsmith (andrew.goldsmith@uconn.edu)‚ Tuesdays 1-4PM Section: 2 (Partner: Ana Charalambides) Abstract In polikiotherms it is known that the amount of locomotion varies based on the environmental temperature. We believe that this is caused by differences in the neural activity. We therefore investigated how temperature changes affect the extracellular

from hundreds‚ even thousands of other neurons. Each signal is either excitatory or inhibitory. Excitatory signals increase the likelihood of an action potential happening‚ inhibitory make an action potential in a nerve cell less likely. The action potential is a nerve impulse. Once the excitatory signals over power the inhibitory signals and action potential is triggered. So the neuron then fires‚ sending that impulse down its axon‚ transmitting information to another cell. The firing of a neuron isn’t

system control the bodies conscious action whilst neurons in the automatic nervous system control involuntary action which keeps the heart pumping and internal processes working. The soma of a neuron is electrically charged reacting to electrical disturbances from either sensory or neighbouring neurons via it ’s dendrites. These brief changes of electrical voltage (action potentials) are conducted away from the soma and along the neurons axon. Action potentials travel quickly to the tip of the axon

fires an impulse‚ called the action potential‚ down the axon. The impulse is protected and sped along its way by the myelin sheath‚ which is a layer of fatty tissue that surrounds the axon. Each neuron receives signals from many other neurons. Some signals are excitatory‚ and some are inhibitory. If the excitatory signals minus the inhibitory signals exceed a certain level‚ called the threshold‚ then the signals trigger an action potential. When the action potential reaches the axon terminals‚ called
