That's a cute little video bur with very much impact
Ответитьyour voice is so cute and charming !!
ОтветитьThanks so much !!
ОтветитьHow does a non-polar molecule dissolve in a polar dissolvent? Is there some kind of phenomenon with H bridges or another solute?
ОтветитьThis 5 minute video explained my 4 weeks worth of classes for my environmental engineering class.
Ответитьimagine a world where we weren't surrounded by air YOU WILL BE ....... DEAD
Ответитьgood job!
ОтветитьThe best video EVER! thanks a lot for this chrystal clear explanation
ОтветитьGood video
ОтветитьGreat 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
ОтветитьThanks for this video
ОтветитьEvolutionist don’t care. They only think about the development of life. And forget about the many ecosystem’s that are vital for life. How did Darwinian evolution develop and sustain these. Think!!!!
ОтветитьThank you so much!! this video was really helpful, straight to the point and well explained!❤
ОтветитьWell nice voice
ОтветитьI 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.
ОтветитьThis is very well done! a lot of well explained content.
ОтветитьVery helpful 👍
ОтветитьVery informative! I needed this most!
ОтветитьVery well explained
ОтветитьReally 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.
ОтветитьLove this video explanation! Very clear! Thank you!
Ответитьwow cool
ОтветитьAwesome. It is simply awesome. I learnt lots of things from here. Absolutely amazing.
ОтветитьThank youuuu, this helped tons
Ответитьwhen you make something to be understood
Ответитьwater = 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)
how cool is that intro
ОтветитьThat was remarkable.
Ответитьthis explains it so simply and so well wow thanks <3
Ответитьwhich is higher oxygen... hot water or cold water?
ОтветитьNice video to watch, it helped me a lot to know the concepts,
ОтветитьThanks allot! Was searching for the awnser why warm water holds less oxygen but found allot more! Thank!!
Ответитьcherrs cherrs
ОтветитьIf 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.
Ответитьso 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.
ОтветитьCommunication 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.
Great job💯👍👍
ОтветитьGreat video!
ОтветитьI love the animation of your video ... 😆
ОтветитьThanks . love from Afghanistan
ОтветитьHad to watch this 4 school stfu and lma
ОтветитьI hope in recent years you've changed the voice over people. She sounds so scary.
ОтветитьAmazing video, thank you.
ОтветитьAh that is the dissolved
ОтветитьCyanobacteria do not undergo photosynthesis. They make their food chemically (chemosynthesis)
Ответитьvery swag
Ответить1234567890 nice nice nice nice nice nice nice nice
ОтветитьThanks dear🤗
