In the neuron, have synaptic vesicles

i'm not sure about my answer

Your answer is wrong,  

The neuron conducting an action potential toward the synapse is called the presynaptic neuron. The axon terminal of the presynaptic neuron contains membranous sacs called synaptic vesicles which are filled with neurotransmitter. The gap separating the cells is the synaptic left.

The answer is D} Axon Terminal

the answer to you question is   jet streams

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
