For the temperature I said a water bath as it keeps the temp constant


Is using ice and hot water to maintain temperature right? We did this in class :frown:

I kinda found it hard, as I did'nt know the structure of the plant which was 5 marks I think. Also, I thought the 6 mark question will be regarding polydactly and cystic fibrosis. Anyway hope the chemistry exam on Thursday goes well.

Same! I was annoyed that nothing about fossils, speciation, stem cells came up.. but overall it was an average paper. I didn't like the chromosomes question at the end, I messed up on the three numbers and I didn't like the question about the number of squares.. i just guessed :/
