Eduqas AS Biology anyone??? B400U10-1

so now that we've done both exams, what do you think the overall grade boundaries might be?

absorbtion

I got absorption as well

ah good, i hope this is correct

can u wright out some of the other answers u got to questions and i will reply with what i got?

I'll try my best to remember. The question about rabbit faeces and why the soft and hard differed was because cellulose gets digested near the end of the digestive system in the caecum and therefore glucose would remain in the faeces until digested again to absorb the glucose in the small intestine. The hard faeces were because some food didn't contain cellulose and therefore all the nutrients were absorbed.
I'm a bit worried about the heart defect question as i put it was because there wasn't an av valve and backflow would occur and not as much oxygen would get absorbed in the lungs, though my friends didn't have similar.
Question 1 was easy, it was just transport of co2
Also does anyone have any ideas as to what raw mark would be required for an A. I thought it would be 80 percent but someone mentioned 70 percent in which case i can aim for a A with more confidence

I agree about the rabbit one but i said the hard pellets are the ones that have had all the nutrients abosorbed on the second digestion, I dont know if i explained it that well but i did say that so should get the marks. I said that there wasn't a septum or valves and so oxygenated and deoxygenated blood would mix and give an absorption value that was lower than someone without these issues for the 100% sat blood. I said 70% cuz no way will it be 80% at the level of difficulty compared to the old papers. I'm sure u can get an A, im really really not sure what i will get! will just have to wait and see

Yeah i definitely missed out the septum but hopefully i'll be able to get 2 marks maybe for my explanation of the valves. I wrote about lower values due to less haemoglobin available to absorb oxygen in the lungs. If it's 70% i'll be so happy tbh because i don't think i've dropped over 20 marks. Considering it's a new paper as well it would make sense that they would lower grade boundaries. I'm just annoyed our college did eduqas because their markschemes and questions are complete bs

Sadly this spec doesn't seem that well documented. I could try to get a hold of the papers from my teacher as she might have some? Will try tomorrow.

Have you got hold of the papers yet? If you have, please could you send it to me.

Thanks

She said I wasn't allowed to have them until we got our grades
