Answer:
The correct answer is option B ( ligand gated channels opened by neurotransmitter molecules).
Explanation:
Input region or postsynaptic region or dendrite is the site of neuron cell which receives the impulse from the pre-synaptic neuron at the synaptic junction.
The cell membrane of the dendrite is embedded with ligand-gated channels which opens up in response to the ligand (neurotransmitters) produced by the neurotransmitter vesicle of axon or output region of neuron.
The neuromuscular junction is such a case where acetylcholine receptors present in the dendrite opens in the presence of acetylcholine.
Thus, option B ( ligand-gated channels opened by neurotransmitter molecules) is the correct option.
Answer : In radioactive decay, the half-life is the length of time after which there is a 50% chance that an atom will have undergone nuclear decay. It varies depending on the atom type and isotope, and is usually determined experimentally.

Skin cells are together to provide protection and strength.
Answer:
Neurons are similar to other cells because neurons have a cell membrane, a nucleus, cytoplasm, mitochondria, organelles, and carry out processes such as energy production.
Neurons differ from other cells because neurons have extensions called axons and dendrites, they communicate with each other through an electrochemical process which we just talked about, and neurons have specialized structures such as synapses and chemicals such as neurotransmitters.
