Publishing science is a critical step in doing science. And, as scientists, we are taught early on what is expected in a science paper. There are five substantive parts:
Abstract, that summarizes what you did and what you found,
Introduction, that describes your hypothesis, question and the background to the field,
Methods, where you describe what you did in enough detail that the study can be repeated,
Results, that reports what you found in words, tables and figures,
Discussion, where the implications of your findings are described,
and then supporting sections like acknowledgements, keywords, literature cited and online appendices.
While it is important to make sure that you are including all of these sections in your manuscript and putting the right information in the right section, there is something that is not here that you absolutely cannot omit. Good science. Your science must be novel, well conducted, well analyzed and reasonably interpreted.
Good science can be enhanced by good writing, and a proofreader can help here. But no proofreader will be able to rescue your manuscript if it is describing science done poorly.
