Question
what is osmoregulation?
Thanks for using AllExperts. Osmoregulation is the mechanism by which organisms control the balance of water and solute (salt) within their bodies; it is a critical part of maintaining a constant internal environment (a process known as homeostasis). Organisms constantly lose water and salt through urination, ventilation, perspiration, and defecation; they have consequently evolved mechanisms to decrease this loss to the point where survival is possible. These mechanisms are quite numerous; a few examples in humans include anti-diuretic hormone, the renin-angiotensin-aldosterone system, and the ability of the large intestine to absorb water from digested food.
A straightforward discussion of the topic can be found here:

I will answer all biology-related questions through the undergraduate level. I will explain unclear concepts and suggest approaches to solving problems, but would prefer not to completely solve homework problems for you. If you are completely stumped on homework, tell me what you already know and I will help you as much as possible. Please do not ask me for ideas on school research projects; part of research is determining a suitable area of investigation, and that's not a task that should be completed by someone else. Please don't simply send me your homework for solutions. If you are having difficulty after you have started an analysis, I will be happy to direct your thinking; in particular, I would prefer to not simply solve pedigrees for students, but I will be happy to assist in solving pedigrees that you have already started. If you don't understand how to analyze a pedigree, I'd highly recommend watching this video, in which a biology professor explains the basic concepts of pedigree analysis: http://www.youtube.com/watch?v=HbIHjsn5cHo
Experience
I have a BS in Bioengineering with a concentration in Chemical Engineering (which included a heavy focus on biology), and have taught biology, biochemistry, and related subjects for some time now.
