Are either or both of these articles considered "primary literature" and why or why not?
In the sciences, a primary source
Primary scholarly references are the gold standard for your background research as a scientist. Secondary scholarly literature—review articles, books, encyclopedias, handbooks, etc.—are useful entry points, but shouldn't be used alone. Follow up on the citations you find in secondary sources to get to the primary scholarly references.
You can use general web search engines as a tool to help you find primary literature and you can use digital primary literature, but you cannot cite websites in your written work for this class.
Why not? Because:
“The Literature Cited section of a paper may refer only to permanently archived material. If a reasonably diligent scholar 20 years in the future could not be assured of finding a particular source, it would not be acceptable as literature cited.Because Internet sources typically have a short half-life, they may not be included in Literature Cited sections unless there is reasonable evidence of permanency (e.g., Ecological Archives).”
So how can you use the web well for this class?
