GCSE OCR 21st Century Triple Science (CBP1-7) Thread

The last question did it say micro organisms have a lot of ethical issues or a few because I think I misread it to be a lot so I didn't tick it.

I know I was unsure what to write!! So annoying when there's the whole heart, genetic modification..and we get an ecosystem, oh well another exam down anyway :smile:

Well at least they're nearly over. :biggrin:

did you write about the circulatory system in that diver question because I did and I think i might just be wrong lol i talked about how she has oxygen so it goes through the heart and everything about the heart really. I also wrote she may feel discomfort breathing because of the pressure she has been etc but I think I'm wrong. What did u write?

That's correct, it was about bioaccumulation,
you could also mention destroys biodiversity, causes problems in food webs, contaminates water

It was the best biology exam so far, IMO!

I also mentioned about eutrophication as well as bioaccumulation will they cut marks for writing about that

Nope, you won't get marked down for including the wrong thing in your answer, they mark positively so they only mark what is correct

That was a surprisingly easy exam! On the capillaries question, I think I may have wrote about active transport instead of gas exchange...

I did too until I stared at it for a minute! Points:
As she dives, there will be increased pressure
Results in lack of oxygen (cant exactly remember what it said in the box?) down there for too long which is possible as she is a deep sea diver
Also as she breaks surfaces there could be many bubbles - discomfort & ears popping.
Reduce this by swimming slowly up.
