Wait what where the questions please

yh. tbh it was kinda easy. i did miss out the 1 marker about conservation cuz my mind went blank byr apart from that... it was GOOD. hbu??

Wait what where the questions please

I wrote CITES

i think that was right cuz thats what my mate said as well

Stages of Meiosis 2 features of homologous chromosomes what are the stages in meiosis that leads to genetic variation they asked about pathogens and immunity memory cells DNA fill in the gaps and DNA enzyme inhibitor for DNA polymerase then it was translocation question then a question on beetroot pracfical how to assess repeatability magnification calculations the conferences for biodiversity and 2 reason why elephant needs transport system elephant ecg and what it would look like if it was tachycardic then uses of stem cells

wow amazing memory. i couldnt remember as soon as i walked out. 😅 do u have any ideas what might come up in paper 2.
apparently its likely for stats tests to come up and to interpret them. also, plants and enzymes might come up. biodiversity and classification is like 99.99% gna come up cuz there wasnt even an mcq on that

Enzymes, Water, Phylogeny & classification, evolution , the lungs fish & insects , blood vessels

What are all the questions and answers please?

I don’t know it was a week ago and we didn’t get the like full mark scheme it’s just my teacher HAd the exam paper after the exam and showed us so we can see the answers she’s written in
It was a very fair paper nothing TOO hard , if u revise you’ll do good on it.

If you remember anything pls let me know I'm crashing out 🙏🏼🙏🏼

Tm it was NOT a difficult paper plus if your school doesn’t do AS they probably won’t even use those questions ? Because they were on 2025 paper this year

It was a difficult paper omg they asked about mitosis give anothe property either then repair and growth wtf am I suppose to say 😭
Btw I did the actually exams

Ummm... we are talking about OCR AS, right? @Shaan31300's predictions were quite accurate (thank you), but I don't remember seeing a question on mitosis and growth & repair. Other questions included chromatography, spirometry, heart, and general practical questions, as well as a few calculations.

It was a one marker in paper 1 about either than grow what is mitosis used for. The answer was asexual reproduction
