Instead, "Effects of Several Environmental Factors on Growth of Populations of Escherichia coli " (if more than two or three factors were manipulated) would be appropriate.The same applies if more than two or three organisms were studied.All background information gathered from other sources must, of course, be appropriately cited.
) If the title had been "Effect of Environmental Factors on Growth of Escherichia coli ", the reader would not know which environmental factors were manipulated.
If the title had been "Effects of Light and Temperature on the Growth of an Organism", then the reader would not know which organism was studied.
For example, "Effects of Light and Temperature on the Growth of Four Species of Bacteria" would be correct.
The researcher would then include the names of the bacteria in the Materials and Methods section of the paper.
The section headings (Abstract, Introduction, etc.) should be centered and the body of each section should follow immediately below the heading. If one section ends part of the way down the page, the next section heading follows immediately on the same page.
One important general rule to keep in mind is that a scientific paper is a report about something that has been done in the past.
The "rules" of writing a scientific paper are rigid and are different from those that apply when you write an English theme or a library research paper.
For clear communication, the paper obviously requires proper usage of the English language and this will be considered in evaluating your reports.
The abstract section in a scientific paper is a concise digest of the content of the paper. A summary is a brief restatement of preceding text that is intended to orient a reader who has studied the preceding text.
An abstract is intended to be self-explanatory without reference to the paper, but is not a substitute for the paper.
