Was it asking me to compare base G and ATP? Didn't see a label saying G on the figure apart from that base?
G was a nucleotide

se thing
i suppose by having those things it will actually lead to speciation. coz hardy weinberg says that no natural selection happens but idk.

I thought that was assumptions for Hardy Weinberg?
Yeah G was a nucleotide but had a base guanine whereas ATP has Adenine was what I was meant to say then ATP has 3 attached phosphate groups whereas nucleotide has only one

could you say that one has a deoxyribose sugar and atp has ribose sugar?
☝🏻Yeah that’s ok as well 😄👍
Three phosphates compared to one
Ribose instead of deoxyribose sugar

oh fuks sake. completely forgot to write about the temperature. literally only wrote about it increasing and decreasing population size.


same:frown: i missed out temperature

i said selection pressures, variation in characteristics, emmigration and immigration?

I went for mutation, natural selection and selection pressures lmao

Variations in characterisitics and mutation probs count as the same mark tbh
Who else talked about convergent evolution and analogous structures for the mongoose

nice i did. thought it was wrong. did you say something like they had similar selection pressures and so adapted to ways similar to a cat in africa?

what did u say for what other evidence scientist could find for increase in temp. i said water height and levels of CO2?
Do you have the link to it? Had no idea what to write to make it up to 6 marks lol.

So it had nothing to do with speciation ?
