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.
The mitosis stops when chromosomes are at the maximum condenstation, it is practically metaphase but the chromosomes are not attached to the spindles so they don't form the equatorial plate.
Phillip is the father as the baby has a heterozygous blood type B which is IBI in order for this to have happened the IB part would have came from the baby’s mom and the I or blood type O part would have came from the baby’s dad.
