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

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
