AQA GCSE Biology 12 May 2015 [Official Thread]

Didn't a six mark question on it appear last year?

If I've got it right myself, yes.

it was an additional 6 marker only for higher so it could come up again. Speciation isn't on foundation so it always finds a way on to higher could be a 5 marker just as easily. My teacher explained the first 6 mark question which is question 2/3 on higher is the last question on foundation (their hardest) and is the exact same on foundation which means it could be answered using C grade knowledge for full marks and any additional 6 markers is only on high paper..

What would the six points needed be?

depends what the question asks tbh. If the question is for example:

The blue eagle originated from England. In 1919 some of them migrated to new Zealand to escape world war 1. Explain why in 2015 they can no longer successfully interbreed to produce fertile offspring.



The two species of blue eagle have become geographically separted. Naturally, genetic variation is a factor because each population of blue eagle has a wide range of alleles that control their characteristics already so they will have slight differences within the species. The two populations which have become isolated will undergo natural selection which is where the organisms with alleles better suited to their environment will allow the organism to survive and reproduce; therefore passing on their alleles which allowed them to survive. Over time, speciation will occur which is where the populations of blue eagle will become so different that they will be unable to successful interbreed to produce fertile offspring.


Made the question up so its not accurate at all idk if there actually is an eagle called blue eagle haha but the answer is lol

1a is indeed about concentration of mineral ions and auxin

4b... carbon dioxide,, photosynthesis, glucose, cellulose, strengthen cell wall.

can you post all the answers

Hi guys I was wondering for homeostasis do you urinate more if it is hot or cold and which one contains less mineral ions (is dilute) and why is this??? Thanks

6 marker on B2 is likely to be on anaerobic and aerobic respiration , since it occurs in living organisms. They might ask when and where does anaerobic respiration and aerobic respiration occur and give examples. Just like June 2014 although instead of giving examples of diffusion its probably giving examples on aerobic and anaerobic respiration, since its occurs in almost all living organisms

Just my opinion guys , Good luck for tomorrow.

Have a look at the previous pages of this thread

Have a look at the previous pages of this thread

praying the 6 marker is the differences between mitosis and meiosis though

urinate more if your' e hot because ur more likely to be drinking water and keeping hydrated in the cold the urine is low but concentrated when cold. As for why i think that is beyond the spec
