Different research papers written according to the same set of style guidelines will be formatted and structured similarly.

Explanation:

The set of style guidelines establishes the format in which the papers are written, despite the number of citations, the sources and the materials used in the investigation.

The set of style guidelines generally determines: the size of the paper sheet; recommended fonts; the size of the letters; the size of the margins; how to make citations; which sections are essentials; how to include graphs, equations and tables; within others.
