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:
Peer acceptance
Explanation:
Peer acceptance is the acceptance for something that may be negative or positive by a person due to peer pressure. It depends on the popularity of the peer groups where a person can maintain a peer relationship. The peer acceptance of relationships is a crucial part of a child's emotional development. Peer acceptance provides a broad range of children's development. This development could be a social relationship, cognitive acceptance, recreation, participating in groups to solve the problems. These groups help children to explore their emotional, social and cognitive development.
They keep discount rates, I believe.
Answer:Kayla was experiencing peer pressure
Explanation:
It is hard to make a decision but it get even worse when others influence our decision making process because it may be confusing if we should take what they suggest or continue following our own guts.
When someone of your own age group influences how you make a decision this is referred to as peer pressure.
Kayla wanted to go and see the movies but Sue suggested she was staying home and studying which in return put pressure on Kayla to also stay at home and study because she now probably feel her decision to go out to the movies is a bad idea so Sue has influenced Kayla decision making process.
Both the Mayans and the Aztecs developed advanced calendars and had an understanding of astronomy.
Hope this helps :)
