could someone explain this to me?

I tried to google functional complementation but there was no real explanation just articles. 

I don't exactly know what it is or what it does or when one would use it. 

thanks

I did this whole problem, and I keep on getting 2 extra people. But I add everything up and they all equal to one, so I don't know what I'm doing wrong. I'm in Evolutionary Ecology, and we're working on genetics problems, but they shouldn't be so bad 'cos I'm not in Genetics (this is a prereq for genetics).

HELP! Cystine Tellurite blood agar (Culture Media) [Jul. 8th, 2008|09:47 am]
Biology Help

I'm studying Introduction to Microbiology right now and we are in the topic of culture medias. Our professor gave me a research assignment regarding to the cystine tellurite blood agar.

But I wanted to brawl my eyes out and cry! I cannot find any information about this specific culture media other than its purpose.

Purpose: Isolation of Corynebacterium diphtheriae

I tried finding information in the internet. I looked for the Journals of Microbiology in my school library but they're only a few and none of the information I need is there. I scanned the books of Microbiology but we have only 20+ books regarding the subject of General Microbiology.

I live in a 3rd world country and in not-so top school in our country that's why reference materials are very limited. So, I hope you understand.

Questions:
1. Look for the purpose. (I already have that one).
2. Identify the mechanism how the different component is useful for the isolation of a specific bateria.
3. Mechanism action
- How this particular organism inhibit the growth, what are the steps by steps of the mechanism action, what happened from the beginning to the end and why.
4. Cite the literature.

HELP!

I am writing a research paper.

in the methods and material section I wrote down what I calculated and showed how I calculated it.

I calculated distribution coefficient 


Now the readers do'nt know what that is. So where do I put in a definiation of what it is?  I don't think I define in the methods section.

Do I define it in the intro?

thanks
