The article in the journal is the secondary source.
Explanation:
A research literature review can be constructed by taking information from two types of sources which are grouped as primary sources or secondary sources.
The primary sources include the original research papers, excerpts written by the scientists himself or any other original documents.
Any article published in magazines, newspapers and journals that reflect the original result but do not have the exact words written in the research paper are all secondary sources.

Answer:
I don't know about it. which subject and which class is this
Answer:
This is because the voltage gated sodium channels which opens for the influx of sodium ions, which caused increased postivity of the axoplasm closed, with simultaneous opening of potassium channels.
Therefore depolarization stopped, thus propagation and transmission of action potential (caused by depolarization) which cause the reversal of charges in the membrane (making the axoplasm more negative) for the voltage rise to 40mV also stopped.
In addition the simultaneous opening of voltage gated potassium channels caused K+ to leave the axoplasm to the external environments. This makes the inner membrane to be negative further lowering the potential, to -75mv. This is re-polarization.
