hope it helps ;)
Answer:
The Abington School District promoted religion in their school, by compelling learners to participate in a Bible reading program. The US Supreme Court's decision directly addressed case of Abington V. Schempp where students were being forced to participate in school-sponsored religious activities. The Supreme court held that the school was violating the establishment clause by just having this Bible reading program , even if it was voluntary.
Explanation:
During that time under the Pennsylvania law, public schools were required to start the day reading at least ten verses from the Holy Bible. The Bible verses were to be read without comment, everyday during opening of each public school. However the establishment clause, prevents the government facilities from establishing a religion.
Information, skills, and strategies that have been accumulated through experience are grouped together under the category of Crytalized intelligence. Fluid intelligence is define as the ability to solve new problems, use logic in new situations, and identify patterns. And Crystalized intelligence is represent as the ability to use learned knowledge and experience.
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.
