What type of stimulus is required for an action potential to be generated? What type of stimulus is required for an action potential to be generated? a suprathreshold stimulus multiple stimuli a threshold level depolarization hyperpolarization

A threshold level depolarization.

Explanation:

In a neuron, the action potential threshold is known as the point of depolarization where the neuron fires, when the neuron reaches a point, it will fire and if it does not reach the point of depolarization, it will not fire and it helps to transmit the information to another neuron.

A neuron transmits the information with the help of electric impulses which are sent through its axon. When a neuron in an inactive phase, more +ve charged ions recline outside the axon membrane. In the process of stimulation, the axon membrane admits more Na+ ions and providing the neuron more +ve charge.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

answer; polycythemia is the correct answer;
