I need to write a background research paper on a science fair experiment, but it needs to be formatted in MLA. I looked up some examples of a MLA essay and research paper but there seems to be something that bothers me. At the end of some bit of information or a sentence there seems to be a small word in parenthesis.

I saw this in most of the references I found. There seems to be a similarly worded citation at the end of the paper so I assume that it is telling the reader where the information before the parenthesis came from, but I do not know for sure. If I am correct then is it alright(or uncommon)to cite definitions and how should I note the definition at the end of the sentence? I am not sure about anything because this is my first time writing a MLA formatted paper. I hope you can help me a bit.
