That means that it is not going under depolarization‚ we use the term resting potential. Modality gated channels- specific to sensory neurons‚ open in response to mechanical forces (i.e. stretch‚ touch‚ pressure‚ temperature changes or chemicals) Ligand- is a particular molecule that causes a receptor to open. The ligand gated

Resting potential is created by a transport protein called the sodium-potassium pump. Resting potential occurs when ions are distributed unequally on the inside and outside of cells‚ and when cell membranes are selectively permeable to different ions. K+ is particularly important for the resting potential. The membrane is highly permeable to K+. In addition‚ the inside of the cell has a high concentration of K+ and the outside of the cell has a low concentration of K+. K+ will naturally diffuse

1981) The Free Rider as a Basis for Government Intervention by E. C. Pasour‚ Jr.* Department of Economics and Business‚ North Carolina State University The "free rider problem‚" arising from the fact that an individual may be able to obtain the benefits of a good without contributing to the cost‚ is discussed in a number of different contexts. In the case of a "public good" where the provider cannot exclude‚ a good which others provide for themselves will also be provided to the free rider. In the

| | By definition‚ a free enterprise economy (also known as: capitalism or a free market economy) is an economic system controlled chiefly by the individuals and private companies instead of the government. Characteristics of a free-enterprise system include economic freedom‚ voluntary exchange‚ private property‚ and the freedom of profit motive. Capitalist societies generally achieve a higher standard of living because of the incentive to work: capitalism prefers harder and more efficient workers

Opportunity cost Have you ever been in the situation deciding which cloth to buy? Have you ever facing the dilemma of to study or to play? Have you ever consider as a seller and choose to lower the price or raise it? In the field of economics‚ here’s a solution for you. The magic word is “opportunity cost”. Opportunity cost in terms of economy is the highest-value alternative one has to give up to engage in an activity. In other words‚ using the same resources such as money and time‚ the best

Action potential to occur in a neuron. This will be achieved by firstly‚ defining the purpose of neurons in the body along with a description of the components within a neuron and how they enable information to be passed through the cell membrane and on to other neurons. Secondly‚ the resting potential of a neuron will be explored with relation to the concept of selective permeability and the purpose of the Sodium - Potassium pump. Thirdly‚ the molecular basis of the Action Potential will be

1. The chief economist for Argus Corporation‚ a large appliance manufacturer‚ estimated the firm’s short-run cost function for vacuum cleaners using an average variable cost function of the form. AVC= a + bQ+ cQ^2 (the 2 is suppose to be exponent) Where AVC=dollars per vacuum cleaner and Q=number of vacuum cleaners produced each month. Total fixed cost each month is $180‚000. The following results were obtained: Dependent Variable:AVC R-Square
