just started IB two weeks ago and i already have to make a 40min presentation 😭 you're a life saver fr

[@Elec2ricLearning]

Well that sounds intense haha... Glad I can help. Good luck!!

U r a god istg u saved me

[@carlollavan4980]

Thanks i now really understand binary fission

[@god9331]

yo bro just wondering, do u cover hl topics as well? or are they integrated into the sl videos with their respective sl topic?

[@Elec2ricLearning]

Right now all of my videos are only the SL topics. I do have an HL only practice question video though, so feel free to check that out!

@@Elec2ricLearning alright, thank you!

Okay so like what if the broken down molecules of the cells in the liquid couldnt come together because they were already damaged by being together then ripped apart. Maybe it can only happen once. Like if you burn a tree log and plant the ashes it isnt going to grow a tree even though everything that that tree ever was is in those ashs..i hope this question makes sense!

[@Elec2ricLearning]

Great question! I think to better understand it you need to look at the chemical level instead of the cellular level. Cells are made up of molecules which are made up of atoms, and the atoms within molecules are moved around all the time - we call that a chemical reaction. Just because a cell is "broken" apart does not mean that the atoms/matter is broken or damaged. It simple just gets changed and can be reused again. In your example of burning a wood log, when that happens a combustion reaction occurs which releases molecules like carbon dioxide into the air (not everything in the tree log is in the ash only). A different plant can then extract that carbon dioxide form the air and use it for photosynthesis to build sugar molecules. So yes if you burn a log that specific log will not grow back, but the components of that log can be used to build another life form. I hope that helps and also makes sense!

Best of luck! You got it!
