1. Action potential reaches the axon terminal and depolarizes it.
2. Depolarization opens voltage-gated calcium channels, enabling influx of Ca into the neuron.
3. Calcium binds to specialized proteins on vesicles (containing pre-made acetylcholine) and triggers them to fuse with the neuron membrane at the synapse.
4. Exocytosis of acetylcholine into the synaptic cleft occurs.
5. Acetylcholine diffuses across the synapse and binds to nicotinic receptors on the end plate of the myocyte.
6. Activated nicotinic receptors, themselves ion channels, cause cation influx into the myocyte and generate an end plate potential. This eventually gives rise to the full depolarization within the myocyte that enables contraction.

Answer:
Dominant character is expressed in both the condition i.e. heterozygous and homozygous.
Explanation:
In genetic the dominant allele is signified by capital letter and the allele which is recessive is signified by the smaller letter. The dominant character can be expressed in both the condition that is homozygous dominant(TT) or heterozygous dominant(Tt).
Therefore even the presence of a single allele of dominant character in the gene, the dominant character can mask or suppress the recessive trait from being appeared in the phenotype. Therefore pea plant that is heterozygous for the tallness trait have the dominant phenotype.
