AQA BIOL5 Biology Unit 5 Exam - 22nd June 2011

how are most people studying for this exam with only 1 past paper to use? I only have Nelson Thorne tb.

Yeah I was thinking the same. AQA just love their random animals though, so I think we should expect to see a female african spotted cane toad and others alike.
Congrats on your Liverpool offer btw =]
Would you mind if I asked you what GCSE's you got, because its the reason they rejected me.
Thanks!

does anyone know where we can get the january 2011 unit 5 paper and mark scheme? i need practice but only one unit 5 paper on the aqa website!!!

I have no idea how to revise for the synoptic essay. Any help? :|

hey guys
in germ line gene therapy, the gene is inserted into an fertilized egg cell and is allowed to develop into an embryo, and the embryo is implanted back into the organism. Does this mean that the organism that the embryo has been implanted into has the corrected gene now and is able to pass onto offspring? or does it mean that the embryo, once it develops into an individual, has corrected gene and can pass onto offspring?
which one of the two is right?
because i am confused

i have over 20 essays and analysis on them if anyone wants i can email it to them

That would be very kind of you.

Plan plan plan. Planning is definitely the key to writing a good essay. Find an essay title, write a plan for as much as you can think of (set yourself a 5 minute time limit, that's what you should spent in the exam). Then, if you've got enough points try and write the essay itself, that's good practice (you want to have done a few before going into the exam. Ensure that all of your points aren't from the same topic, they like to see breadth of knowledge as well as depth- for example, if you were asked 'Why do offspring with the same parents not always share the same characteristics?' of course inheritance is a good place to start, but also talk about the different types of mutations (non-sense,mis-sense,deletion and silent mutations) and what causes them. You could talk about how independent segregation and crossing-over increase genetic diversity etc. Always refer back to the question, why do mutations result in different characteristics? If you get stuck on a question, read around the subject from the textbooks and look on the internet. Using material 'beyond A Level', i.e. you've bothered to find information on topics from elsewhere than the text book will get you extra merit.

I wouldn't revise as such, just plan a lot of essays and use that as a starting point to identify topics you're a bit rusty on.

Here are some possible titles for you:

1-How the structure of cells is related to their function.
2-The structure and function of carbohydrates.
3-The Biological importance of water.
4-The ways in which different species of organisms differ from each other.
5-Describe how the structure of different polymers are related to their function.
6-Why offspring produced by the same parents are different in appearance.
7-The importance of hydrogen bonds in living organisms.
8-The movement of substances within living organisms.
9-How the structure of proteins is related to their function.
10-The process of osmosis and its importance to living organisms.
11-Inorganic ions include sodium, phosphorus and hydrogen. Describe how these and other inorganic ions are used in living organisms.
12-The causes of disease in living organisms.
13-The role of the cell surface membrane in living organisms.
14-How bacteria affects humans.

I beleive it's only the offspring will express the correct gene because the gene is not present in any the maternal organisms bodily cells.
