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:
El presidente y su gabinete de ministros representa en ala ejecutiva del poder publico. Esto significa que tienen a su cargo la administración del país y de los recursos del gobierno, a nivel nacional, y dependiendo del país, a nivel reginal o municipal, ya sea de forma directa o con transferencias.
El presidente y su gabinete también tiene a cargo el hacer válida la ley y su cumplimiento, y es por esto que bajo su poder también se encuentran las fuerzas armadas y la policía.
The answer is<u> "Jamie has not used true random assignment to conditions."</u>
Random assignment alludes to the utilization of chance methods in psychology analyses to guarantee that every member has a similar chance to be relegated to any given gathering.
Study members are randomly allocated to various groups, for example, the experimental gathering, or treatment gathering. Random assignment may include such strategies as flipping a coin, moving dice, or allotting arbitrary numbers to members.
Note that random assignment varies from random selection.
Answer: The industrial revolution fundamentally changed everyday life.
Explanation:
The industrial revolution has positive effects on society. It has made people's work much easier. People were much more productive thanks to the involvement of machines in production. The amount of food increased significantly and was more accessible. Also, thanks to steam engines, people traveled much faster and thus gained time.
The industrial revolution also had negative effects, especially when it came to workers. The workers had no rights; they worked twelve or even sixteen hours a day. There was no adequate protection at work, so injuries were frequent. Workers who suffered serious injuries and were unable to work would often be left to fend for themselves. Also, the early Industrial Revolution did not respect any environmental regulations in industrial plants. Environmental pollution was common.
Wodiczko’s video installations commented on the social
injustice. This was one of the main themes in the works of this celebrated
Polish artist who was known for the practice he called Interrogative design. With his Interrogative design which combines technology
with art he wanted to raise awareness of the social problems that plagued
the people across the world.
