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:
Actor/observer bias
Explanation:
In psychology, the actor/observer bias refers to the tendency to attribute our own actions to external causes while attributing other people's behaviors to internal causes.
When the results of a situation are negative, if the negative outcome happened to the person, the person will likely attribute the outcome to external circumstances. But when it comes to other people, the person will attribute the outcome to the other person behaviors, habits or actions.
In this example, Jeremiah falls and thinks the ice is brutal. <u>He is attributing the fall to an external circumstance (the ice)</u>. But then, when his friend Ed falls on the same spot, he says his friend is really clumsy, <u>attributing the fall to an inner characteristic of his friend</u>. Therefore, this would be an example of actor/observer bias.
