That means that it is not going under depolarization‚ we use the term resting potential.

marble the potential energy to hit the target cup. Energy is the ability to do work. Potential energy is the energy of position and kinetic energy is the energy of motion. In order for the ramp to be successful‚ the ramp had to have the right amount of potential and kinetic energy. If you have too much potential energy than the marble would have too much kinetic energy and the marble would not land inside of the target cup‚ it will go right over the top of it. If you have too little potential energy

Strategic management involves the use of innovation to gain a competitive advantage in the industry. In the article‚ “It’s Tough Being a Small Fry at McDonald’s”‚ it talk about how does Ted Lezotte get more stores in the hands of his better operators. Innovation is a topic in strategic management. Through getting rid of smaller franchisees allows McDonald’s to speed renovations and the implementation of new technology‚ such as the self-ordering touchscreens being tested in about 250 locations.

exist? Let’s go back to the definition of peace and war. Peace is commonly referred as an era without conflict‚ when people live in harmony. War is usually defined as a time when people fight for honor or their country. Although these definitions are quite accurate‚ it does not adequately explain what is peace and war‚ and I doubt the simplicity of these two words. What is the cause and effect‚ the balance‚ between these two “words”‚ if there is one? Peace and war does not always have to refer to

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.

What is an action potential? To put it simply‚ it is a message that is sent down the nervous line. The message is written and is sent from the central nervous system. That message is addressed to muscles or glands. This essay will explain what happens before‚ during‚ and after an interneuron action potential. To accurately define an action potential‚ it is part of the incredible course of events that occur during the firing of a neuron. When a neuron is not firing signals‚ the interior of the

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
