Which past papers would you recommend solving, or find the hardest?? You can send us questions you are struggling with and we are happy to solve them in a video 😍 contact us on: biologybel3araby@gmail.com
we technically have to pick the value which gave the lowest number cuz it has the highest ratio value, so option a is 0.8 and option b is 1 which is larger thus a is bigger (ratio is technically a fraction so 0.8 :1 would be 0.8/1)
originally you're supposed to solve the question by finding the sa and vol of each option then pick the one which had the highest sa : vol ratio, it doesnt really matter whether its width or length cuz either way its ratio would be the smallest due to it having the smallest value :)
I literally love this explanation the most she knows what shes doing and her voice is soo calm and clear i cant thank you enough

it would be better if u could remove the background music
easier to understand the explaantions
thank you for the feedback!
@@biologybel3araby799 yes please
Hi, I dont really understand question 17. The SA/V ratio of A is 0.8:1 while for B, it is 1:1 so shouldn’t the answer be B?

0.8 is a lower sa: volume ratio
Apparently u don't use surface area to volume y just take the one with the smallest measurement
Hi, for q17 I'm getting B as the highest SA:V ratio, so why is it not the answer?
A - 0.8
B - 1
C - 0.7
D - 0.5
Thanks a lot! Your solving vids are really helpul. Do you have any plans to make similar solving vids for A LEVEL past papers? Cheers!!!
hello in quetion 35 theres something between the epithelium cells isnt that goblet cells??
I think that's the mucus
for question 17:
arent dimensions read as width x length x height? so wouldnt the 3 in option a be the width

thank u
Thank You
My pleasure!
Your toooooooooooooooo fastt
