lol yeah, but i thought that the textbook co's would jump at the idea of making a few tiny changes and then releasing a brand new edition for $80 haha.

and what are these podcasts? i'm interested.

[physics]

ex bio student here who only got like 30 raw
good luck 2010 year 12 bio-ers

[The Detective]

Thanks first SAC is very soon! Weekends I'm going to hardcore study bio 

[TrueLight]

i should probably note that water does move regardless of water channels via osmosis even though its charged or polar because of its small size...but the channels are needed to make it more efficient and faster..

ppl should also know the difference between osmolarity and tonicity..

[Biology]

My prac is next week My teacher is going through the content of the prac in a single period class and then we have the next day's double for the prac.

Yeah my friend and I had a discussion about cholesterol in the plasma membrane, I had to rely on Douchy's podcast to understand what it's role is, because for some strange reason it isn't covered in the Nature of Biology book +_+ and my teacher explained it too And yeah the prac is in class test.

So we'll be tested on our knowledge of movements across the cell membranes, and perhaps also membrane structure right?
We may be asked to explain what causes the difference when placed in isotonic, hypertonic and hypotonic solutions etc. ?

I thought it might similar to the prac I did in Bio 1+2, we did potatoes.

[TrueLight]

osmolarity and tonicity..

Oh.... lol..

lol you do right?

I have another Biology SAC coming up, on enzymes this time.
We have to put liver in various  pH solutions, and then hydrogen peroxide in various pH solutions.We then graph the "height in bubbles" of the oxygen produced in the test tubes...
Hmmm...

Sounds like chem .

I remember we did something like that

[TrueLight]

hey when do you guys learn about the immune system? is that like the last topic?
or is it more dna, protein stuff now?+ transport mechanisms?

[stonecold]

i think immune system is towards the end of unit 3 yeah?
you mean like viruses and stuff?

[TrueLight]

lol i dunno im asking you...
yea stuff like that....

[stonecold]

well it must be because unit 3 in my book is chapters 1-9, and i read up to chapter 7 on the holidayz and it still hadn't come haha.
so yeah must be right at the end of unit 3.

[TrueLight]

ah okay lol
u read alot and hasn't it been like 1 month only?
well goodluck...learn about transcription/translation...all the cellular stuff... its important for later too (like uni and beyond..)

[stonecold]

thanks. 

i'm listening to douchy podcast right now haha!
wish he would get to the damn point!!!!!

[TrueLight]

lol.. i watched 5 seconds of the adp-atp podcast and then closed it.. he seems very chirpy and happy and excited..lol its funny..
