Osmoregulators: organisms that avoid changes in their internal environment and have the ability to keep the solutes at an optimal level (‘regulate’ solute concentrations within the body), regardless of the differing external environment. i.e Mussels close their mouths in order to keep the salt levels in their tissues the same as sea water
Osmoconformers: organisms that tolerate the changes in the environment by altering the concentration of their internal solutes to match the external environment. i.e the fiddler crab accumulates salt into its tissues to match seawater and pumps out the excess when exposed to fresh water.
You should also talk what estuaries are and what change in the environment that requires enantiostasis to occur for these organisms to live in their ecosystems

Wow okay thanks for the information! I'll thank you now but read it later as its all going over the top of my head right now (2 trial papers does that to you, especially when one is English Adv paper 2 modules)

Them feels man, them feels. English trials are over though so that means only the "easy" subjects are left. Y'know, physics, chemistry, maths, SOR II and Bio

You seriously did not just put SOR II and "easy" in the same sentence.. :P
I agree that the sciences are certainly easier than english, math comes down to the mindset and level being assessed but omg i am so screwed for SOR II. Perhaps even more so than english. Section III and IV are not looking fun :-\ :'(
But its my last exam so i can relax a bit :D
Skidous:
I don't mean to brag but I'll have you know that I came third in SOR II and I barely did study for all 3 assessment tasks

I dont want sympathy but I actually tried in all my assessment tasks and are still ranked 7th (out of 20) for SOR II. Life is not fair lol.
