Hormones in our Meat Products

My topic is adrenaline hormones found in our meat animal products, and so far I am doing pretty good with finding research.  My only issue is trying to put everything together to make it sound nice.  I have so many good ideas and opinions and what have you, but putting all of it together into a paper is a bit of a challenge.  Also, I am unsure of whether or not we are supposed to include our own personal opinions and make our paper from a biased point of view, or completely factual? I know that it is a research paper so for the most part it should be research based, but is it safe to include our opinions too?  Lastly,  I am having some trouble formulating an actual question.  I have a topic and overall direction that my paper is going to go in, but I just can't come up with a question. Maybe towards the end once my paper is closer to finished then it will be easier to come up with something.  I hope everyone is coming along well with their research!
