Geography influences our life now and it did so in the past. Because of this it helps understand the reasons for some events.
For example geography helps you understand why ancient Greece was composed of many small independent city-states rather than one empire: Greece is composed of many islands and valleys separated by mountains, and it was easy to defend those settlements so they were not conquered by other settlements ( as it was the case in other countries).
Answer:
Excitatory
Explanation:
The neurotransmitter will cause an excitatory effect on the neuron. When the neoronium receives this effect it is stimulated to show a response to the stimulus, which in this case will increase the sensitivity to sound.
When the neuron is stimulated, it undergoes some changes. Initially, it is important to note that stimuli of various natures can excite neurons, etc. In addition, the stimulus must have a certain minimum intensity, called the excitation threshold, for the neuron to effectively respond to it. Otherwise, no changes will be triggered.
