I'm predicting that diseases will definitely be there in paper 2 cause there wasn't much about it in paper 1: and yeah I wanna ask about the last question if you can remember your answers just tell me. I screwed up that question I guess.

How was the paper as an overall?
What did you write for:
1) why vaccines should be tested?
2) the order of mitosis process
3) why there's a small increase in glucose level after a meal?

no side effects/Resistance/ actually work??
glucogen is released from pancreas converts glycogen to glucose
i and a few others did not think prophase came up but some said it did 50/50 i think metaphase(centre) anaphase (middle) telophase is the order (splits 2)

Yeah even I didn't write prophase the stages I put stage A telophase stage B metaphase and stage C anaphase and I wrote the same answers for the vaccines as you did so I'm glad

The other is homozygous recessive. The disease is recessive.

Btw what were your answers to the Mitosis question, the last one in humans?

Quick check. I put hydrogen carbonate indicator for the breathing test. Would that be wrong? I didn't write limewater as it asked for an indicator solution in particular. Not too sure though.

I put A - telophase
B - metaphase
C- anaphase
And the order was BCA
The last one I wrote it's a cell division that helps in the growth and repair of body cells as well as development of zygote into an embryo

Not sure tho
