i talked about how they would have less competition for light is that correct or no?

I said that too

Could you predict chemistry topics and physics please!

oh okay. so basically focus on nephrons, cloning/miccropropogation/genetic modification. make sure transpiration is covered. fsh,lh roles r imp too. and the nitrogen cycle. thats all i can think of atm

I still think that the answer might be CO2 but I'm just praying that the mark scheme will be lenient on us and give us marks for light... fingers crossed

Any ideas about chemistry and physics paper 2?

ok fyi usually i just predict it w/ what i usually see in past papers and whats in bold in our spec.

so first chem: theres a great emphasis on organic chem so make sure yk everything abt fermentation. hydration, alcohol tests, word eqs with carboxylic acids and everyones fav: drawing out polymers. then make sure the chem tests chap is clear. they can ask tests for insoluble salts and the equilibria chap in physical chem. and be prepared for any mol calculations and electrolysis. now tbh chem isnt like bio where ive noticed a steady trend... ppqs can sometimes even ask for the 3 types of bonding so make sure u learn everything just focus on these ig.

so physics: honestly i havent done phy past papers recently so ill do them and get back to u on that

You are a life saver, at this stage I need direction and you have provided me with one. Thank you so much.
I look forward to your physics predictions as physics is my weakest and I really need a miracle

What did you say for the increase in population due to farming and deforestation of the light plants? I said there’s more greenhouse gases such as CO2 so more co2 for photosynthesis so increases reproduction so increased population. Is that right?

I said this as well!! although I said more PS means they produce more glucose for nutrition so they can survive . (Should have mentioned they use it to respire though!)

yo this is so funny to me cuz i did the regional one and none of the stuff i mentioned came for my paper 💀 glad i helped u guys tho lmao

do you do the International GCSE Edexcel Or the GCSE Edexcel?

international. my qs were abt root hair cells, eutrophication, energy test thing and at the end there was a 5 mark on the effects of smoking in the lungs

Sounds right, but I did not get that 😭

I said that due to deforestation, the habitats of the predators of the dinoflagellates would be destroyed so there oido be a decrease in the population of the predators and therefore an increase in the population of dinoflagellates
