Amoeba Sisters please stop. i hate how you constantly make gaming references. We watch you so much in biology. I’m sorry but please. The gaming references kill me. Literally portal references. I don’t even want to take credit for the class anymore because of your Naruto and portal references. Thanks. 🙏🐪
This video is funny
@@fadi8166 dont hate!!!!
Amoeba Sisters be mine sister cause my teacher is bioenfugy
Fadi Ghazal don’t watch here then
Amoeba sister you guys teach better than my own biology teacher lol
Hey i am a biology teacher!
(but i make students watch these videos all the time) I can't visually explain it better, so why would i?
Matthew Cowell ur one of those teachers that say “BELL DONT DISMISS YOU I DO”
@@matthewcowell Right there with you!
Staright facts
so true
who has an exam tomorrow?
Me
Me
next week
Right now
this morning
I just learned more about diffusion in 7 minutes than I would in my science class lol.
Lmao same
Same
CFC fvfv
90% people watched it for school
10% just like science
10% here!!!
Lm3rr same
@Lm3rr yes
i like science
I slept through my diffusion lesson so I'm here.
1:47 Diffusion is when the net movement of a substance travels DOWN its concentration gradient. This means it moves from a high concentration to a low concentration. Diffusion doesn't just happen in water, it happens when you spray an air freshener.
2:46 Net movement = overall movement but it doesn't mean the molecules can't move around the other direction or stop moving altogether. The overall/net movement is from a high concentration to low concentration until equilibrium is reached. Diffusion is a passive transport, meaning an input of isn't required. Kinetic (movement) energy is enough. Passive transport does not require added energy.
3:44 Facilitated diffusion is a type of diffusion when molecules still have a net movement from a high concentration to a low concentration but because the ion sizes are too large to travel directly through the plasma membrane, the ions travel through proteins.
4:21 Factors that can affect the speed of diffusion: temperature (higher temperature would mean more movement of the molecules, increasing diffusion rate), distance (the greater the distance that needs to be travelled, the slower the diffusion rate), characteristics of the solvent (is the solvent dense? This could slow to molecules down and decrease the diffusion rate), characteristics of the substance travelling (substances with greater mass will have a lower diffusion rate compared to a substance with less mass), characteristics of the barrier/plasma or cell membrane if it's passing a barrier (small non polar substances pass through a cell membrane easier than large polar substances) and the surface area/thickness of the cell membrane (a large surface area and thin membrane = faster diffusion compared to small surface area and thick membrane).
Dang this comment helped me complete my biology work
Thank you for this video! As a college bio student its nice to hear another explanation of stuff other than just lecture classes. The fish story at the beginning is also a great way to help get people interested and to stay focused on the content you are teaching as it is pretty difficult for me to stay focused when tons of info is being thrown at me. Thank you for helping me study for my exam!
....And again another scientific concept explained in its most interesting way by the amoeba sisters!
Christmas always comes early when Amoeba Sisters uploads.
bruh

Ohhh. That Ich stuff must've been what affected the fish in that one episode of Spongebob Squarepants! Interesting!
Your videos are always packed with fun and "wow" moments!
I'm doing an online course and we're given a textbook and told to teach ourselves
Your videos are amazing😊
who's here during online school because ur teacher sent you a link because you're doing a lab?
Omg I am lol
@@nadiatalal1 lol same
The egg one
I'm not even in school anymore but heck I'll watch these
ok
I feel like this has been more informative than the entirety of my GCSE course
Who's here from biology class
Me

You could have just started with "So today we're going to talk about how farts work!"
LOl
I wish there had been such great learning experiences around "when I were a lad" :). How can kids not be excited to learn when science is presented and taught this well!? Wonderful!
I AM brasilian and, i watch your videos to learn inglish
I couldn't understand our lesson no matter how many times I read it. This really helped me in understanding what the hell is diffusion😆
This literally makes so much more sense than in the book
as a fish keeper, the thing about methane blue is true, it is really helpful with treating fish
Please never stop making these videos, they are my favorites and so darn good!
Love the art, love the funny little quotes, love the content, love that this is going to be on my test soon. Thank you Amoeba Sisters!
Awesome and easy to understand.
Thank you. 😊
Wow what’s this? NEW Original Amoeba Sisters content!😱
Never thought this day would come
I'm in anatomy and physiology 1 and your videos saved me!!
you sisters are my literal science teachers rn since its lockdown my teacher makes us watch u guys
"Lazy River" you guys crack me up! Thanks for the great video!
you guys are amazing! i am learning so much!
The fact that ur videos make more sense that want my teacher tells me amazes me. Keep it up
Love the way you explain stuff, really helped with science, and I am subscribing
Same
i love your channel, lot of support from me!!!!!!
keep making these kinds of videos, for entire biology
Pls do a video on algae
this is so helpful since I mostly fall asleep in most of my classes especially biology chemistry and maths and we cannot forget physics so yeah thanks for not letting me sleep and helping me with diffusion.
& there u are a new terrific video by amoeba sisters .... Seriously i really love your videos .
It's so hard to pay attention to the info with the picture. They're so funny!!!! I love it.
Thankyou soooooo much! GSCE’s are hard after coming from Australia and I’m doing Triple Science, so you are helping a lot :D. Thanks for this channel!
This makes so much sense now, thank you
I don't even take science classes at school but this video was really fun and easy to understand! (I came across the word "diffusion" while prepping for my geography test and wasn't sure if I really grasped what it means! :,D)
easy to understand!so good!
I am an exchange student in Germany, so it is nice to have you to explain this to me in English.
How bout you diffuse the Cuban missile crisis
wow
Thanks ,you are doing great work.
It was a great help for my unit test for finding the factors Thank u I'm a grade 8 science student # It was actually another explanation video so i took the points from this
I love your passion for studying science; and your humour is great, too. Thank you for sharing your talent. :)
Very helpful I love watching animated scientific videos even I am old enough to quit doing that
It really helps to understand quickly and helps in remembering easily
Thank you☺
In my class we do two lessons a day so your channel helps for the test next week.
You guys are just great, I'm doing the whole playlist for my Biology Olympiad as a 7th grader. Love from Pakistan
MARVELOUS AS ALWAYS.....
Please make a video on Plant Kingdom Classification. Please!!!!
I watch these science videos at school! Keep up the good work!
good video!
Hi! I finished biology last year (in chemistry now), but im going to stay subscirbed to this channel because it helped me so much, its really the least i could do. The day before tests, id take notes on your videos and they made so much more sense than the teacher. Thanks for getting me through bio :D
Thanks!
I LOVE YOU AMOEBA SISTERS, YOU SAVED MY GRADES I LOVE YOU SO MUCH
I remember watching these freshman year… it helped thanks
Hey Amoeba Sisters, this Diffusion video you made is cool! Your videos are helpful to our learning. Remembered learning this back then in Yr 9.
i learned so much more with this than from my bio teacher lol
Well explained!
My 9th grade biology teacher Mrs.Spear told me that you used to be a teacher at Vines High School in Plano! I was so surprised! My 7th, 8th, and 9th grade science classes ALWAYS showed us your videos. It's such a great help. It's also really cool that you used to be our school's teacher! Were you for real..? hmm ;)
Fun fact: a more natural way to treat ich is to turn the heat in an aquarium up to 86 degrees C as that is the temperature that ich dies. Leave it there for a few days and your fish will be cured without harming other life in the aquarium such as beneficial bacteria which is crucial to converting waste into less toxic substances such as Nitrate. Thanks for the vid!
Is it bad that I binged like 3 videos and I already know more than everyone in my class?
The length of that intro tho...
Please do a video on dissolving! You teach me so much and I know it would be helpful.
Sweet video! Any chance you'd do gene expression and epigenetics?
Lovely teaching
Thank you so much I have a bio test tomorrow and I feel so much better about it
Can you guys make an updated video of Enzymes?
You guys teach better than teachers
This is so cute I can't! And awesome explained! thanks
You make science fun and me happy
Best science TH-cam channel for science ever, your helped me alot my SAT subject test bio, thank you
Dear Amoeba Sister,
Could you please explain the science of Brining (in the context of cooking) ?
Is it passive Diffusion of salt? why doesn't Osmosis occur drawing the water out of the meat? but instead we have a more flavour infused result.
I hope you see this.
hu¿¿¿¿¿¿¿
Thanks for this video, lt cleared all my doubts 🙏
Explained it so well! Thanks
You guys are simply awesome...
@Samuel Williams dudes pressed
these are so nice for college. Thanks.
this one got a little off track--
Wow good job, better than my teacher's lectures and khan academy videos she links to them. Thank you.
Great Video this was so helpful to me please keep the videos coming .
Tysm! I have this for science and ur teaching me more than school
Thank you soo much, and lots of love ❤️
Hi!!!!!!!! Thank you!!!!!!!
(Now I definitely can't go to bed! Not without watching this!)
Thanks for the heart!!!! ❤️ I'd heart you back but I can't. And I can't click like more than once. Who made TH-cam? I need to talk to them.
I subbed even though it's the first time watching ur channel :) nice content
you are better than our teacher
This video helps me in my Agriculture course
Thank God u girls exist!!! Please don't stop this amazing work, if possible! 😘💓
simp
thank you for this video. I now understand what diffusion is and also the definition of equilibrium which means when particles moved from a high concentration to a low concentration until they are evenly balanced. F3-K.L- L.H
Thanks! You can always turn something hard to easy🎉🎉🎉
The protein that is used during facilitated diffusion, is that the aquaporin?
It is so useful to me thank u!😍
Amazing, understandable easily, high absorption rate, love and thx.
brilliant video
It would be more interesting if you can make more detailed videos on different concepts. After all biology is all about details!
me in bio 131 :) thank you amoeba sisters :)
Yesss I needed this vid!
Thanks this really helped me
Wait so it’s basically the overall movement of particles from a high concentration to a low concentration. Some ways you can tell the movement of the particles Is by the heat, mass, and distance of the room?
Thank you! I'm going to share this with my 6th grade students as we talk about the movement of oxygen and carbon dioxide related to the respiratory system. :)
Didn't ask
@@shrekbeliver6619 HI

Oh my goodness, I was trying to learn wth diffusion is for so dam long, amoeba sisters, thank you so much, you teach better than my freakin biology teacher does, who need school when I have you!
