8 0

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.

solmaris [256]
The average distance is 16,000 km
Converging rate is  10 cm/year
1 km = 100,000 cm
 = 16,000 × 100,000/10 cm/year
= 160,000,000 years
It will then take 160 Million years to collide.
