OCR B7 Unofficial Mark Scheme - Monday 19th June 2017

Perhaps the mark for blood pressure, but probably not for tissue fluid: plasma is forced out of the flow of blood and not the cells themselves.

I'm pretty sure that fermenter question asked for FOOD products, but either way, if I mentioned foods it should still be right....right?

I said 1) quorn and other meat substitutes.
2) rennet.

i put meat subsititutes and cheese too! it literally said FOOD, i dont understand why everyone keeps saying it didn't lmao

Don't worry too much- B7 is always people's worst module, you on average score one grade or two worse on it than the other ones since the boundaries are high (only top levels take it)

Exactly! For the cheese/rennet thing, would rennet be wrong? I didn't understand what the revision guide said rennet actually was, I put cheese and crossed it out for rennet. Oopsies.

im not 100% sure but i think you're supposed to put chymosin which is the vegetarian subsititute for rennet, and i think you need to write the food that the enzyme is used to produce (cheese) you might still get the mark for rennet though!

I hope so.

Good luck with C7 and P7!

then why is there a foundation tier if only top levels take it

Which method was most sustainable for timber harvesting?
I put Method B. Is that right?

did this question specifically ask to state the most sustainable method? because i just said "unsustainable timber harvesting removes food sources and habitats for organisms, method C is the least sustainable because as the cycle goes on the amount of teak produced rises dramatically which means more trees are cut down so there are less for future generations" how many marks does anyone think ill get for this?

The two mark question specified that it was in the food industry so I think you had to put Quorn (single cell protein) and Chymosin/Rennet. Unfortunately, I forgot about Chymosin and put alcohol instead so probably only got one mark. However, I don't see how medicine like penicillin is plausible when it was specifically referring to the food industry, don't know. ¯\_(ツ)_/¯

i said enzyme for food processing such as chymosin and single cell protein such as yeast - will i get 0 marks

In my opinion you'll definitely get 1 mark for mentioning chymosin but since you said single cell protein such as yeast instead of Quorn then they may not allow it, but surely not 0 marks!! O:

History was good thanks for asking! My hands are still dying from the intense writing in the intense heat... RIP x-x

history is the worst for writing def!! at least you're free from it forever!!!... unless you're taking it for A-level ahah

I'm taking it for A-Level!!!! xDD How about you, what do you plan on taking?
