Explanation:
President Jefferson purchased Louisiana from the French to insure safe trading routes for the U.S. and since France was in need of money due to their war with Britain, Napoleon sold the Louisiana Territory to the United States.
Answer:
Explanation:
Action potential
It is the potential or power or electrical energy required to generate impulses and provides communication between the neurons is called action potential. Normally cell membrane consists of potential is called resting membrane potential() -70mV. The action potential is due to exchange of different ions across the membrane.
Phases of the action potential in a neuron are
i. Depolarization- it is caused by the influx of sodium and calcium ions through the opening of voltage-gated sodium and calcium channels. sodium ion influx is rapid than the calcium ions membrane potential -70mV to +30mV.
ii. Repolarization - It causes the efflux of potassium ions into the cell through the opening of potassium channels. the membrane returning to resting membrane potential.
iii. After- Hyper polarization - in this stage the potassium channels remain open and causes re polarization and comes to normal membrane potential.
The generation of impulses(depolarization) in neuron mainly depends on influx sodium and calcium ions without these ions, no action potential developed and neuron firing does not occur.
If the drugs inhibit these channels, no depolarization, no action potential, no neuronal firing or communication.
The channels involved in an action potential are voltage-gated sodium channels, potassium channels, and calcium channels.
The action potential is required for transmission of information one are to another area in the body.
The responses to different stimuli is due to action potential.
Well, to put it plainly, it is very difficult for a society to develop a unique culture and role in global politics and economics when they have to worry about drinking clean water more than anything else.
The statement above is false. The Equal Pay Act accentuates four compensable elements—aptitudes, effort,responsibility, and working conditions. The Equal Pay Act 1970 is an Act of the United Kingdom Parliament which disallows any less good treatment amongst men and ladies as far as pay and states of work. The Act has now been for the most part superseded by Part 5, section 3, of the Equality Act 2010.
