The formation of an action potential can be divided into five steps. (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached‚ all Na+ channels open and the membrane depolarizes. (3) At the peak action potential‚ K+ channels open and K+ begins to leave the cell. At the same time‚ Na+ channels close. (4) The membrane becomes hyperpolarized as K+ ions continue to leave the cell. The

1. Voidable Contract: An agreement which is enforceable by law at the option of one or more of the parties thereto‚ but not at the option of the other or others‚ is a voidable contract. A contract is voidable when one of the parties to the contract has not exercised his free consent. One of the essential elements of a formation of a contract for example‚ free consent‚ is absent. All voidable contracts are those which are induced by coercion fraud or misrepresentation. The person whose consent is

The two concept that relates to the “Tunnel Vision” episode are‚ culture-bound values and class-bound values. In this episode Katy is a young women that got into a habit of spending every minute of the day doing something she deem productive and Brandy is a mother who accidently used a credit card that was for work and go fired‚ after that she got fired and she could no longer keep her finance balance. What Katy deems productive is to exercise and to keep a good interactive network with her friends

CONTRACT AND RELATED OBLIGATION Prof. Hillman I) Theories of Obligation A) CONTRACT: Agreement with Consideration – Bargain Theory of Consideration Definition: A promise that is supported by consideration because the promisor gets something (extracts) from the promissee in exchange for the promise. Ex: I tell Alice I will sell her my piano for 400 dollars and she agrees. I promised my piano in exchange for something (400 dollars) therefore my promise is enforceable. 1) Bargained

Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy • Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example‚ the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly‚ a drawn bow is able to store energy as the result of its position. When assuming

THE WORK DONE BY A CONSERVATIVE FORCE ALWAYS HAS FOUR PROPERTIES: 1. It can be expressed as the difference between the initial and final values of a potential-energy function. 3. It is independent of the path of the body and depends only on the starting and ending points. 2. It is reversible. 4. When the starting and ending points are the same‚ the total work is zero. The total mechanical energy ME = K + U is constant. Object moving in a uniform gravitational field gravitational a

Discussion and Conclusions Many obstacles to my potential strategy are worth overcoming. Since the brand new policy is to add extra taxes on smoking and fining the smoking companies for their actions‚ then one is able to make sure that people comply or go out of business. A way to overcome the challenges is to have someone from each company represented in Congress (Kottke‚ RN‚ GH‚ & ML.‚ 1988). This may mean making sure that there is someone in government that is passionate about this issue‚

LAW OF CONTRACT NOTES INTRODUCTION. A contract is an agreement between two parties which is enforceable by law.An agreement is made when a person signifies his willingness to do or to abstain from doing anything with a view of obtaining the assent of the other party. Such act or abstinence is said to make a proposal.The person making the proposal is called the offeror and the person accepting the proposal is called the offeree TYPES OF CONTRACTS: Contracts may be classified into: -Written

which cell has the larger resting membrane potential? Explain. If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2. Predict the effect of a reduced extracellular concentration of Na+ on the magnitude of the action potential in an electrically excitable cell. If there
