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.

Answer:
<u>It means that the test would have high reliability and not so for the validity.</u>
Explanation:
Even though the test may have reliabiltiy because it can be consistent in some of the structure of evaluation. This doesn't mean that it would be a valid test, because it is biased.
The psychometrc propertes are measured both by validity and reliabiltiy. This means the score can be reliable but as it is biased, it is not reflecting the knowlede and skills so it loses it's validity.
Answer: Law of closure
Explanation:
Based on the information given in the question, Sean continues to swear the moon is full because of the law of closure.
The law of closure is the perception of people with regards to pictures, letters, etc. when they believe that the items are whole even though they aren't complete. Here, the moon isnt full but Sean thinks it is due to the law of law of closure.
