[iqrahafsahussain]

your videos are always a miracle literally

[mett]

Thank you so much for your explanation!

Please, ma'am was wondering if you could help me out with this?

How does surface area to volume ratio play an important role in water and air pollution?

[seokjinkim]

does generating enough heat via high metabolic rate refer to more rate of exothermic reaction (since this type of chemical reaction releases heat)?

Hello I was just wondering, to make the most out of these videos, is it better to pause and read what’s on the page first before listening to you, or do you reccomend listening to you first then reading what’s on the page? I struggle to multitask by reading what’s on the page and listening to you at the same time. Too much going on for my brain at the same time . Sorry I know this question sounds really silly

hi could you explain a definition on what exactly an exchange surface is?

[Wojbest_YT]

2:42 the length of two boxes is 2cm so the length of the side is 1 cm not 2cm so its 2*1*2 = 4 not 8

Hey, can you re-order your playlist in accordance with the AQA Specification?

[archimistry]

Hi, have you done gas exchange videos yet? I can't seem to find them :(

[sarimiari]

Can you please organise the playlist like the book order

[mizzyy]

dont smaller organisms have higher metabolic rates?

[zoewillcocks]

Will surface area always be bigger than volume? It’s just in large animals the ratio is smaller than a small animal
