3 things: Amazing graphics, simple and to the point info. best wishes for future videos.
WHOOOOO
NICE GREEEMPHICSS
The graphics are satisfying af huge props to the editor. I also appreciate the informative video. Thanks
That is a lovely video with a lot of information in it .... Thanks for uploading that
Very lucid and informative.Great Work. Eutrophication description could not have been better. Hats Off!
Love it! Great video, really helpful, informative, and inspirational. Thank you so much!
Great job! Really nice quality video and super clear.
Thanks allot! Was searching for the awnser why warm water holds less oxygen but found allot more! Thank!!
Brilliant, along with a lovely commentary :D
This is indeed a very informative video, with a great message! Thanks!
This is very well done! a lot of well explained content.
What a nice and simple illustration... It helps me much in understanding how those oxygen come in and come out of water... :)
Concise and brilliantly explained.
I liked how you gave all your references but mostly the salt concentration affecting dissolved oxygen was interesting. Though i still don't fully understand Eutrophication.
There are certain elements that serve as food for living things such as trees and underwater plants. These are nutrients that help them grow, such as... phosphorous, nitrogen, etc. Just like humans can get sick from consuming too much, so can plants. This makes them grow at a rate higher than normal, not allowing the ecosystem in the water to work the same. Fish may not be able to swim in open water because the plants in the water are so overgrown. These excess elements in the form of food for the plants, usually come from waste from factories and stuff like that. So that is why the speaker talked about trash. Eutrophication is when a body of water becomes extremely filled with those plants, phytoplankton, etc. and there is not enough space for "normal conditions" for fish, humans, and other living organisms! I Hope this helped :)
That was really well done! Informative little video.
Great video. Thank you so much for taking the time to make this.
Love this video explanation! Very clear! Thank you!
Thanks this video was great! Very helpful! Keep up the good work!
Good to understand,easy to explain
This video will be considered a land mark for our time, in time I promise you, very well done.
The best video EVER! thanks a lot for this chrystal clear explanation
Thank you very much. I really struggled for this . Wow ! What an amazing video. Concepts got cleared 😊
awesome video! very informative :D
Great info. The o2 air saturation was not something I'd considered regarding liberating oxygen from water, and didn't know if water could hold addition Oxygen
Thank you, it is a easy to understand and fun video to learn science topic from.
This 5 minute video explained my 4 weeks worth of classes for my environmental engineering class.
excellently explained
Thank you so much!! this video was really helpful, straight to the point and well explained!❤
Very informative! I needed this most!
Beautiful video, well done:)
Excellent video!
water = Hydrogen+Oxygen
so when fish "breathe" are they breaking the chemical bonds in water to extract oxygen ( and liberate hydrogen) or are they only ever pulling out free oxygen that is mixed into water ( not part of it)
only dissolved!
Beautiful work :)
Wow such a nice explanation
How does a non-polar molecule dissolve in a polar dissolvent? Is there some kind of phenomenon with H bridges or another solute?
Amazing video, thank you.
Thank you. the video was very well done
Awesome. It is simply awesome. I learnt lots of things from here. Absolutely amazing.
this explains it so simply and so well wow thanks
Very well explained
Thanks for the information :)
Great job💯👍👍
Nice video to watch, it helped me a lot to know the concepts,
This video is great! Keep up the good work lavyu
Really well done. I'd like to know though how much of the 'trash' is chemical (fertilizers) or animal waste runoff from agriculture vs. population centers (storm runoff, untreated sewage). The garbage truck image is misleading. I'd guess very little of the 'trash' is what we typically think of as trash: plastic, paper, etc.
Thank you.... It is easy to understand and funny also...
which program/app did you use to make this?
Oh good I have a test tomorrow thanks!
very nice video, Thanks!! 😁
I love the animation of your video ... 😆
awesome video
Thanks for this video
Wow. Again youtube surprised me. Thanks
Thank You!
Good job for basics of DO
This was very helpfull
Very helpful 👍
Cyanobacteria do not undergo photosynthesis. They make their food chemically (chemosynthesis)
good job!
That was remarkable.
Thanks . love from Afghanistan
very helpful
Thank youuuu, this helped tons
which is higher oxygen... hot water or cold water?
my father's farts are dinoflagullates also...apparently a dinosaur crawled up into my father's ass and then died when he was young
Perfect
For a moment there I thought she said dino flatulate. lol a.k.a. dinosaur farts
Well nice voice
how cool is that intro
If the oxygen the plants produce is consumed when the plan dies, the fact that the plants are many or few doesn't change the oxygen content of the water and it is incorrect to say that plants are one of the ways in which oxygen is introduced into the water, because those plants will die in the water in any case.
Good video
Could you please let me know why boiled water doesn't contain dissolved oxygen in it?
Because it's too hot.
The hotter a liquid is, the less dense it is, therefore the less oxygen it holds.
Thanks dear🤗
It's possible to remove the Dissolved oxygen?
Boil the water
Plz tell me the procedure of "determination of dissolved oxygen in drinking water By Do METER "??????
I hope in recent years you've changed the voice over people. She sounds so scary.
so at 2m in you state that plants / alge suply o2 ... then 10 seconds later you claim the opposite by saying plants use o2 to live.
Very informative video!
I thought animals "breathe" in the oxygen from the water molecule, itself. Water is H2O. I thought they just took the O, and the hydrogen would evaporate until it joined with more oxygen to become water again. I don't have a clear understanding of how dissolved oxygen doesn't connect to the H2O molecules and become h2o2. Or, for that matter, why other molecules (like nitrogen) don't connect with the H2O molecules when they enter and dissolve in water.
when you make something to be understood
H.P.C.M.S was here!
Ah that is the dissolved
yes that is the dissolved
Awsome
wow cool

Communication with student :
1. by visual
2. by talking
3. by listening
4. by feeling
5. by action
unfortunately, all University only have talking and listening. 😔. thats why many are C students. or even fail.
Had to watch this 4 school stfu and lma
imagine a world where we weren't surrounded by air YOU WILL BE ....... DEAD
very swag
Hats off
cherrs cherrs
lit vid just not helping with what my teacher said it would
U sounds cute .. anyway thanx*
Ravi Saxena pervert
@@xxdeathsimulatorxx5549 Maybe they didn't mean it in THAT way.
Smh 🤦
If the pfp was a woman, you wouldn't be saying that.
don't give videos like this please
Wanna care for the fish and the ocean ? Stop overfishing to fulfill your eating habits. No matter how much you recycle, the only way to truly minimize your impact on the enviroment is to move to a fully Plant Based Diet. Good luck. Other then that great video. Thanks !

Great video!
