How do neurons communicate with each other?
a) when the action potential gets to the end of one neurons, the electrical gradient change directly causes depolarization of the next neuron.
b) the end of one neurons releases neurotransmitters that influence the membrane potential of the next neuron.
c) neurons are directly touching and transmits electrical signals the same way the action potential moves down the axon.
d) neurons communicate using hormones.

B) The end of one neurons releases neurotransmitters that influence the membrane potential of the next neuron.

Explanation:

Neurons communicate with each other, when the neuron presynaptic relays stimulus, the membrane potential reach at the end nobs of axon and then it gives signal to neurosecretory vesicles at the end of neurons and then, vesicles are filled with neurotransmitters. As, neurotransmitters are the small molecules which contains different chemical composition like dopamine, glycine and acetylcholine. And then, vesicles  released neurotransmitters in synapse. Receptors send signal to the neurons with the interaction of neurotransmitter to generate membrane.

The correct answer will be option B.

Explanation:

Neurons communicate with each other at the junctions called synapse. These neurons transmit the signals impulse which travels in the form of electrically active potential or action potential which gets converted into chemical energy at the synapse after the release of neurotransmitters from the axon terminal .

These neurotransmitter after binding the receptors in the postsynaptic neuron can cause excited or inhibitory action which depends on the type of neurotransmitter as it controls the amount of membrane potential thus, action potential.

Thus, option B is the correct answer.

answer:

it is much easier to find

The most commonly used test is the PCR test.

The other commonly used testing method is CRISPR testing.
