Edexcel IGCSE Biology 9-1 | PAPER 1

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

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 said that too

Could you predict chemistry topics and physics please!

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. 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

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?

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?

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

What u guys predicting the boundary to be

yes i did! it went okay!
