Answer:
Threshold is a specific voltage that is needed by a neuron to generate action potential
the absolute refractory period is period in which neurons are unable to generate second action potential. And relative refractory period is interval following absolute refractory period.
Normally -70mV voltage is required to stimulate an action potential
Explanation:
The relative refractory period is the period occur shortly after the depolarization of a nerve fiber when partial repolarization has occurred and need a greater stimulus which can stimulate a second action potential.
During an action potential, sodium channels (voltage gated) open, and sodium rushes into the cell because there is more sodium outside the cell than inside and after specific time period sodium channels closed and at the same time potassium channels opens which let the positive ions (potassium ions) to goes out of the cell which makes axon negative and again ready for other action potential
The action potential generates at −70 mV which raised it to threshold potential which is above −55mV then rapidly rises to a peak potential of +40 mV and then the potential drops and overshoots to −90 mV, and the resting potential of −70 mV is reestablished.
Sociology is a science that is responsible for studying societies. Therefore, it can identify how social forces influence individuals.
<h3>What is sociology?</h3>
Sociology is a term to refer to the social science that deals with the scientific analysis of human society or regional population.
Therefore, the sociologist is the person who studies societies from different perspectives such as:
- Behavior
- Customs
- Relations
- Division of labour
<h3>How do social forces influence a person's thinking and behavior?</h3>
Social forces are all kinds of social manifestations, these influence the behavior and thinking of an individual because it shows him a specific point of view from which to interpret reality.
For example, the school is a social force that transmits to the individual the idea that knowledge is the means to solve their problems and achieve their preferences.
