omfg. from the 2005 paper: Qu. 27 "The influenza virus has a high rate of mutation which can lead to changes of the viral surface antigens that contain protein. Analyse the impact of high mutation rates for this virus and the implications for human health." Just to let you know, they give...

it increases it by 100 times. so 0.2ml/100ml turns into 20ml/100ml

look look look!! 2002 qu 17 b) Describe ONE current theory about the processes responsible for the movement of materials through phloem tissue in plants. Materials are transported in the phloem by translocation. Energy is used as sugars are actively loaded agianst the concentration...

came first with 88% lolz only 2 people got into the 80s range LOL my class is not really that great. once a girl asked how to spell DNA. rofl!

just curious, what was the highest mark in your class's bio trial?

ok here is a random question: firstly, define what a transgenic speices is. then outline the process used to produce transgenic species. include an example and reason for its use. now gogogogogo!

xylem= passive phloem= active however im not sure if phloem does both. i just learnt phloem uses active.

meiosis gets me all the time. here is what i have in my book: 1st cell division 1. genetic material is duplicated. 2. homologous chromosome pair with each other crossing over. 3. replication (chromatids become visible). 4. Homologous pairs separate. 2nd cell division 5. two daughter cells...

from all the questions ive seen with meiosis they never really ask you for them. i think you just need to know when it duplicates, crosses over, replicates, separates and what it produces. make sure u know that it has a 1st cell devision and a 2nd cell devision stage.

thanks heaps. yeh i would go for the pipecleaners, but thing is i totally forgot how we did it, all i remember is 2X 2 different colour pipecleaners, and alot of twisting and attaching, and might i add some cutting mistakes LOL... it confused me. sooo does anyone have this procedure?

already posted them on the previous page. those are just points i havent got in my book that i forget or dont understand. can anyone help?

Here are the questions i dont get. Someone help me pretty please? :p 'process information to construct a flow chart that shows that changes in DNA sequences can result in changes in cell activity' 'process information from secondary sources to construct a model that demonstrates meiosis...

eww...designing experiments:uhoh: ive been looking through the questions in the past papers hsc success one textbook is very good! alot of the same questions have been popping up constantly i suggest everyone to go over: the work of all the major figures: mendel, pasteur+koch, beadle+tatum...

Does anyone have this flowchart or know how to answer this syllabus dot point? 'process information to construct a flow chart that shows that changes in DNA sequences can result in changes in cell activity' Thanks.

I've just been studying for biology and i thought this page of my book sums up the protein synthesis process pretty clearly. I just wanted to share it with people who find it confusing to understand. sorry if its a bit too small.

In the Blueprint of Life syllabus it states: "Students: process information from secondary sources to construct a model that demonstrates meiosis and the processes of crossing over, segregation of chromosomes and the production of haploid gametes." I remember the model we did. It was using...

you dont actually get your pip mark, but you can always work it out in the end somehow. thats what my teacher said. getting an award would be pretty cool:uhhuh:

uhhh.. it was pretty obvious wasn't it?? i put the quote in my essay with "- John Savage from Brave New World" after it.

bic ultra round stic grip they last for a while and they're cheap so there's no fear of losing ink

i am going to do in from easiest to hardest which is in order anyway. in the wild>speeches>powerplay
