Answer:
A nerve impulse from one neuron affects the activity of a neighboring neuron at a point of interaction called the: SYNAPSE
Explanation:
A NEURON(or nerve cell) has 3 parts:
1. The dendrites(multiple)
2. The axon
3. The cell body
A SYNAPSE is an area where the dendrites of one neuron communicates with the axon of another neuron.
At the synapse, nerve impulses are transmitted from one neuron to the other. This is possible through substances called NEUROTRANSMITTERS. There is no direct contact between the axon of one neuron and dendrites of another neuron.

Answer:
The correct option is A.<u><em> Normal microbiota may significantly impact human health and disease.</em></u>
Explanation:
A wide number of microorganisms are present on or inside of our body. All these microorganisms make up the natural microbiota. The normal microbiota is very important to maintain the health of the host.
However, any microbial imbalance can lead to causing disease in its host. The microbiota of the gut have a disease-promoting effect but can also have protective properties. Differences in this microbiota can lead to serious conditions.
