Answer:
The correct option will be option A (Input, graded potential).
Explanation:
The transfer of impulse through neurons takes place in the form of the action potential. these action potential are generated in the dendrite and moves along the axons which move to another nerve cell at the synapse.
Graded potential is the change in the membrane potential which can be depolarizing and hyperpolarizing depending on the stimulus. This graded potential which leads to action potential is generated in the postsynaptic dendrite.
Since dendrites receive the signals from the pre-synaptic axon of the neuron at a synapse it is also called the input region.
Thus, option A (Input, graded potential) is the correct answer.
Answer:
The nucleus contains a cell's DNA.
