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.

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax

Essay A: What was the environment in which you were raised? I was born in Texas‚ but later moved to Pennsylvania when I was four years old. My family and I stayed there until I was in sixth grade at the age of twelve. I mention this‚ because although I didn’t stay in Pennsylvania for long‚ that was where I was raised. Where I learned to ride my first bike‚ where I had my first best friend and my first crush. I was raised in Chambersburg‚ Pennsylvania‚ not because it was where I was grew up‚ but because

available resources for future generations and also helps prevent pollution. Most of our current energy sources today are not renewable‚ which means that they will eventually deplete. As a member of the Home Owner’s Association I believe that it is extremely important for us to educate our community about the importance of energy conservation. Teaching the community that energy is not a right but a privilege will educate‚ empower‚ and make us aware of the importance of reserving our resources. I strongly

Gattaca challenges the wisdom allowing genetic potential determined from birth to decide the future of an individual? Genetic potential. What does this phrase mean to our society? Simply an aspect of the future to most‚ a mere scientific term that means nothing to some‚ or it could be a devastating reality for others. The film Gataca poses this question and seeks to find the truth behind genetic potential and how it is used to determining the future of an individual. Through the character of Vincent
