Nico's parents are attempting to use a negative reinforcement technique embodied in the operant conditioning framework to increase Nico's studying.
Operant conditioning is a learning mechanism which consists on affecting the strength of a behaviour by reinforcement or punishment, depending if the aim is to increase or decrease it , respectively.
In this example, Nico's parents want him to acquire good studying habits, hence they allow him to quit from tasks he hates at home if he does so, for instance, doing the dishes. Hence, if he does not behave properly he will suffer the consequences and do the dishes. This a negative reinforcement as if the conduct is not appropiate, the response will be the obligation to do a task he hates.
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.
The answer to this question is <span>B) the President may veto Congressional legislation
President has the right to veto the proposal made by the Congress if the president believed that it does not suit his/her plan for the country. The only way for the Congress to override the veto is if they managed to convince more than 2/3 of Congress to vote with both house voting separately.</span>
A small group that rules a country after talking it over by force is called Oligarchy.
Answer:
A group comparison study
Explanation:
In group comparison study, an experiment compares two groups(the beareaved and nonbeareaved adults in the above study) such as in testing the effects of a treatment where a "comparison group" receives either an alternative treatment or no treatment so that it functions as a source of "counterfactual" causal inference for the purpose of the experiment.
