Scientific Literature

Both articles seem to contain level 1 headings for the main title of each article (centered and bold-faced) however, the sub-titles for each section of the articles contain level 2 headings that are left-aligned and bold-faced. Each section of the articles are structured in steps, such as the steps and processes the scientists took to develop and conduct their experiments. It breaks down the processes of the experiment so it is much easier to read, understand, and analyze. Each section identifies what part of the experiment has been conducted and gives a detailed analysis of what occurred or what results were recorded. The first paragraph of each section gives a small intro into what the section will discuss a little background knowledge and a transition from one paragraph to another. It appears that the paragraphs in both articles contain a logical flow of ideas as the ideas are organized in almost a chronological order of occurrence during the experiment. However, I would say that the first article has better flow of topic sentences, while the second article is more chopped and could be read in sections without going through the entire article.
