The answer is: A. The federal government
The federal government can determine the criteria of immigration depending on what the nation currently need. (the president would have the highest influence in determining the criteria).
For example, when the nation need large number of labors, the federal government could make the criteria for immigration become a little bit loose so many people can come in. If the nation need capital injection, the government could change the criteria based on personal net worth.

Once in the synapse, it must be removed quickly or chemically inactivated to avoid constant attention of the post-synaptic cell and excessive firing of action potentials.
<h3>
What is a neurotransmitter?</h3>
- A neurotransmitter is a key molecule that a neuron secretes to affect another cell across a synapse.
- The cell that receives the signal, which could be any major body part or target cell, could be another neuron or gland, or muscle cell.
- Neurotransmitters are released from synaptic vesicles into the synaptic cleft and interact with neurotransmitter receptors on target cells.
- After being recognized by a post-synaptic receptor, a neurotransmitter molecule is released into the synaptic cleft.
- Once in the synapse, it must be removed quickly or chemically inactivated to avoid constant attention of the post-synaptic cell and excessive firing of action potentials.
Therefore, once in the synapse, it must be removed quickly or chemically inactivated to avoid constant attention of the post-synaptic cell and excessive firing of action potentials.
