if you guys have any more questions post them up. i'd be really happy to answer them as it helps me and you.

my understanding is that it is done selectively to remove toxins that have diffused back into the blood. logically, these toxins would diffuse back into the blood through the reabsorption stage. the body then actively secretes the toxins that shouldn't have diffused back into the blood. so...

so amino acids form polypetides. these polyptides are joined by peptide bonds (the bonds between each molecule). thus forming polypetide chains. protein is made up of one or more of these polypeptide chains.

§ Secretion: This is the process where the body actively transports substances from the blood into the nephron. Some toxins, such as urea, tend to diffuse back into the blood, so it must be secreted back into the nephron. It is also done to regulate salt and water levels again, or to...

polypeptides are composed of amino acids linked by peptide bonds. proteins are made up of one or more polypeptide chains.

nah pretty sure you won't

lets hope 1 night of study can pull it off for this. woot 4 topics 2 learn. this subject got rejected too much. gulp!

sleep before 9.30. up @ 6.30-6.45

haha modern warfare 2 sounds like a good idea.

ah how bout you go before the exams and eat dinner a little earlier the night before?

they will 99% of the time give it. but if they don't i think it is relatively easy to choose what you should be substituting for.

Re: 2008 mathematics school certificate..emergency very tricky questions mostly geome part (a) angle of elevation = theta sin theta = BC/AB sin theta = 27/120 theta = sin^-1 (27/120) theta = 13 degrees, 0 minutes, 10.36 seconds (b) DE = 76- 27 DE = 49m sin 33degrees = DE/BD sin33degrees =...

ah that's probably some of the best advice you can get. if you practise the questions you develop the mind set and techniques to answer future questions more quickly and easily.

well depends on my mood. usually im a tad lazy and just do the exam paper and find where I need to improve. This isn't a real reflection of the hsc exams so you can't really compare your mark in this exam without revision to what you can get in the hsc.

workload will be big. u work hard then you will be ok, you slack off then you'll experience trouble.

give 4 unit a go while keeping 2 unit maths and see how it goes from there.

your droppin chem and you are coming first in it? are you coming 1st in food tech or biology? for scaling, chemistry is better than those two. if you are passionate about those 2 subjects then i would keep them over chemistry but when you are coming 1st in it maybe i wouldn't.

The prelim work becomes assumed knowledge in year 12. you won't be directly tested on it in the hsc but forming your answer to a question in the HSC may rely on you to recall on some of the work you did in year 11. an example off this is calculating moles in chemistry or knowing about the...

no probs, any other questions you have you can PM me if you like.
