What is a heading on research paper?

In a research paper, a heading (also called a header or title) serves to clearly identify a specific section or subsection of the paper. It's a concise and informative label that helps the reader quickly navigate and understand the structure and content. Headings are organized hierarchically, with larger sections having main headings and smaller subsections having subheadings, often using different font sizes and styles to indicate the level. They form a roadmap for the reader, making the paper easier to follow and comprehend.
