Answer:
A). Maria's obsessions consist of intrusive, terrifying thoughts that her son might be kidnapped from school.
Explanation:
Obsession is characterized as the compulsive and recurrent images or thoughts that make the individual to suffer from extreme emotional and disgustful state irrationally.
As per the question, the first statement asserts a true claim in the context of the given scenario that 'the obsession which Maria suffers comprise of meddling, dreadful thoughts about her son being abducted from school.' <u>Maria's persistent and unreasonable thought that her child might get kidnapped causes her to undergo this distressful and anxious state</u> due to the fear. Thus, <u>option A</u> is the correct answer.

<span>Authenticity would give you the ability to pinpoint the source of information that you see on the internet in order to determine whether t could be trusted or not.</span>
Answer:
The history of the Holocaust is complex and vast. While The Holocaust Explained is not able to cover every aspect of Holocaust history, it does seek to aid understanding and help learners to navigate through the sequence of events. This timeline aims to take readers through the main events preceding, during, and following the Holocaust.

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.
