Edexcel 6BIO2 ~ 3rd June 2013 ~ AS Biology

same, hoping for a good paper, but I'm way more ready for it now than I was a week ago, so it's just making sure I actually answer the questions

I was told by my teacher to learn it, so play it safe

Btw, what is 60 ums in terms of a grade (that's what i need to get to scrape an A overall (240 ums) for the next exam).

yes me too, this time last week i was getting 30 marks on my papers
can i check one thing with you regarding against and for stem cells: this is what i know,.is there anything else i should know?
for:
-the stem cells could potentially improve and save lives and treat diseases such as type 1 diabetes.
-the spare embryos are discarded anyway
-the embryos should not be considered human at an early stage
-embroynic stem cells are.more flexible than adult stem cells
against:
-embryos are potentially human
-they have right to life after conception
-ethical and religious objections
-could lead to designer babies
is their anything else fo against and for?

How can stem cells be damaging to human?
Apart from rejection and infection?
Also, species richness- what are the two key points... So the number of species in an area?
And aseptic aseptic aseptic--- I kept on leaving that out in the totipotency and antimicrobial properties!

for against, maybe embryos can't give consent?
and another against is the risk of cloning

What does an Amyloplast actually do, store energy ?

thanks Bobk
ps: its ironic how a few of us on here call you Bobk yet in your TSR name it says mynameisntbobK

starch granules

there's mutations/cancer development

Number of different species in an area

Alright, after revising biology and taking notes to the point where I've almost become mentally unstable, the notes are done.


These are all mark schemes either taken from Edexcel papers, ranging from 2001 all the way till 2013. Some topics were taken from other exam boards because there weren't questions in the (recent) past papers for Edexcel regarding them. Others were taken from mark schemes in books. Some may find this useless some helpful, but I hope you all make good use of these!

Please note that whilst this should cover the majority of topics, it doesn't cover everything! There are some things that are mentioned in the official Edexcel textbook that I was unable to re-create in mark scheme form because I couldn't really find any - one of them is epistasis. Furthermore they don't cover HSW so you'll have to practice and revise from the official Edexcel book for that. Lastly, while I did include diagrams relevant to the topic not every single is included. Don't rely on this solely!

Let me know if you guys want something important added...

what are aseptic conditions?

Yeah I know, but is its purpose for energy storage?

Thank you!
How does that differ from species diversity?
