If you're doing A-level biology you also need that longer diffusion distances will decrease the rate of diffusion because the particles have to travel further.

I never Comment on anyone's video but this channel is so underrated . Thankyou for the video it really helped :)
Yeah same this is basically getting me thru my gcses
This channel is seriously underated.
Nahh its actually nice ngl...he explains better than my school teachers AND my tutor that i took cuz I don’t understand my school teachers
@@pinkszzz underrated means
He gets less (under the rate) than he deserves
@@FasUnknown bro that was a year ago me i was dumb af 😭
XD I FEEL U BEEN THERE
@@pinkszzz 😂😂
This is the most fantastic gcse channel I've seen. I get so appealed to the animations and the way the video is explained. On the other side, it is also short and precise. Thank you so much for your amazing effort.
im really happy to be able to stumble upon this channel.I have no idea how to study for biology as the notes given are very content heavy. I love how this channel summarises key points and makes it easy to understand. Thank you so much
Ah thanks Sherlyn, we're glad the channel is helpful 😊
nahh man, I passed and got a 93% on bio bc of u for real you know how t explain it really well in LITERALLY 5 mins nt 45 mins. Im a senior now taking AP bio nd this has helped a lot. Thank you Cognito.
These videos are great! I share these with my students at the beginning of the lesson to give them an interesting kick start to the topic!! 👍👌
Hi! my teacher does the same but in a classroom it doesn’t help me all that much because i’m prone to zoning out because he doesn’t do anything that keeps our minds on this video, so could i suggest for your students maybe pausing the video every so often in the video and asking questions to ensure they’re actively watching it?
I am really happy I saw this channel, the videos you post are really helpful and I am really grateful for learning biology, chemistry, physics and maths from the channel, it helped me alot. thank you so much!
First channel I recommend to my students! It takes real skill to simplify these topics into a few minutes without ever losing any important content. Stellar job!!
Ah thank you very much, hope your students are enjoying them 😊
Had to watch this in class 💀 thanks for making my day more interesting
I have a test today and these videos will get me happy results! Thank you 😊
Hello, I am a teacher, but I am learning from you ... the content you provide is very, very wonderful ... but I ask you to add the translator to the videos because I am only fluent in Arabic ... Please add Arabic to the scientific videos
Asalamualaykum
you can download a chrome extension called sider which summaries videos, pdfs, webpages etc its like a chatgpt for everything, you could also translate the content it has made or found its rlly gud
Love these videos, especially for someone like me who struggles with reading.
YAY :) Thanks for helping me smash my biology test
Hi I was just wondering how is a concentration gradient maintained? Thanks :)
This channel is awesome helped me learn about the subjects I struggle in at school thank you for this channel
Honestly, this needs way more views. This helped me so much since I have an upcoming test! Thank you!
Ah thanks Xx0bear0xX!!
I have a test tomorrow, and one vid in I feel more comfortable with it! So clear, that really helps and it's really simple 😊 thank you so much

You're very welcome 👍
hi can you please do videos for AS and A-level too for biology and chemistry Pleaseee
well explained thank you
cmon thanks i needed this for my end of yearss
thank you so much very nice explanation really enjoyed and I understood in a very nice manner.
Thanks, glad it helped!!
thank
u sir soo much for ur hard efforts, this is the channel i watch to prepare for my upcoming bio and chem exams. thank again for ur effort
Thanks, very helpful. Keep it up!
This channel is underrated and helpful
Thanks it helped me alot! :)
ty this helped me for revision
Hi, I had a question, since you said diffusion happens when particles move from a high concentration to where there is a low concentration, is it possible that almost all the particles try to move to a low concentration area at once, making that area concentrated? And then, does this process repeat, with the particles going back to now low-concentration areas?
No the particles move from a higher concentration to a lower concentration until the concentration is balanced on both sides
no the particles move from a high concentration to a low concentration until a balance is obtained hope this helps :)
I usually hate science videos but this was great, nice vid
Thank you so much!!
This video is gold
Thank you so much! Life saver! Im passing biology now 😀
Now diffusion is crystal clear for me than you very much
Just perfect explanations❤💯✔
Here for my maths and science weekly tests, wish me luck! 🤧
THANK YOUUUUUU ❤️
THANK YOU!!
This video very helpful me
Tysm! I have a test and this will work wonders.
thankyou so much🤗🤗🤗🤗
You are very welcome!
Thank you sir
Great vid
That video is amazing thank you for that ❤❤
omg right!
thank you !
Amazing!
Cheers - glad you like it! :)
Great vid! 👍
Cheers :)
3:09 is this called osmosis? Thanks for the great video, so much easier to understand! Keep up the good work, we appreciate it ;)
nope
Osmosis is carried out only in water concentration
Thanks a lot
am I bugging or is perfume another form of liquid and when u spray perfume it's just small liquid particles in the air
Thank you for this video very good and simple explanation it really helped
Glad to hear that! 👍
@@Cognitoedu 🥰
GOOD KEPP UP MR BOB
YOOOOO GOD BLESS YOU IVE BEEN TRYNA UNDERSTAND THIS SHIT FOR SO LONG.....
Our teachers sends us links to these vids as revision which are great
What's the difference between a partially permeable membrane and a semi permable membrane because semi permeable is what i get taught at school
I've never understood diffusion better then today
u deserve a golden play button atleast
thank you it really help me but i suggest you increase the voice because the voice is low even when i wear headphones
Thanks
thanks
Why professor say :cell membrane are semipermeable, phospholipid bilateral, easily permeable to lipid-soluble molecules such as O,CO2,steroid hormones. Impermeable to amino acids,sugars, protein. Which contradicts what u said?
ty im revising for a test that i forgot i had xD
Bro u fr js saved me
Can you also teach English grammar on this channel.
question where does it come from
Yes
Thank you for teaching, Cognito. In fact, got more info than my teachers gave. TYSM
THANK UUUUUUUUUUUUU
If I get an A in biology its cuz of this ✨🙏
mock exam in 20 minutes tysm lmao
Lovely😂❤😊
Wow! These vids are amazing. You deserve so much more fame and appreciation. Thanks btw, helped A LOT! 👏🏼 😊 🙏
Oh? Is the biology playlist not yet complete?
This is a lot easier to understand than in class
This has helped so much...
Literally the best....
Thank you ❤️
Thank you Noor, glad you liked it 👍
I thought biology was really hard...when u explained...i understood better over here than my teachers that try to explain to me many times but i still didn’t understand...thank u very very much...even if u don’t reply still thank u!!
Thanks for the kind words Ash! Also sorry for the slow reply 🙃
No problem..keep it up..!!
Thank you for making hard things much easier and interesting 😁💜💜
Only people who finished the whole bio playlist can like this comment
Also amazing playlist Cognito, a moment of silence for every GCSE student revising without you 😔
would you consider doing videos for A-level biology and chemistry?
Yes Please
you deserve so much more! this channel has helped me so much over lock down and now leading towards mocks!
Who else teacher told them to watch it
👇
i havent been attending the class' lectures and your videos are lifesaving when it comes to understaning the concepts! thank you so much for all your effort!
This very educational 69 😅😅😅😅😅😅😮😢
Thank you so much....great channel, helps A LOT. Very clear and attractive explanations. Makes it much easier to grasp the harder concepts. Your videos are used frequently during our online classes. Good luck, looking forward for more videos...🤩🙏
