We're glad that you our videos helped you! Keep it up! 💯

[@someoneelse516]

This video is more than amazing. Why can’t my teacher explain this way? Everything went inside my head sharp and neat, it was quick from nothing to full understanding. Wow! Great job.

still a VERY useful video I'm just a little bit stupid. Thank you very much glad I found this channel!!

[@annabelle466]

Don’t worry! I’m finding it very overwhelming as well but the more we listen and get familiar with the A-level concepts, the more we will understand!

[@l_m_a_o2178]

You sir are an absolute hero! Thank you so much for delivering these videos. As a independent learner doing my A Levels from home, you may have just saved my ass!

[@launchpadlearn]

Best of luck! We hope you got a 💯 on your exams!

[@sharifalomari1852]

this is very helpful but i think there is a mistake at 11:29 doesn't hydrolysis need to be "polymers broken apart" instead of "monomers broken apart" because monomers are the building blocks and polymers are the long chains, right?

[@Isha-s9k]

No because it's monomers that make up the chain of polymers and it's monomers that are either joined or broken

[@amalmohamud1832]

these videos are amazing :) everything explained in detail and interesting too definitely going to recommend to anyone who needs help revising. Hopefully going to help me pass the exams in a month for a one year a level course wish me luck!

[@keshavleitan7800]

Hey mate, really appreciate the work you do in summarising all this in a relatively short period of time, sorry for nitpicking but the molecule for which you labelled "lipid" is actually a phospholipid isn't it? Cuz the circle represents the phosphate head?

[@ok-hd4ir]

[@kinzawaheed2865]

In the summary table near the end, for hydrolysis should it be ‘polymers broken apart’ or what it says (monomers broken apart).

[@felixcharlesworth6378]

I think it means monomers broken apart from other monomers. Polymers broken apart would mean the same thing.

[@dulinaabeywickrama8377]

Since lipids are not composed of same repeating unit ,they are not polymers like other biological molecules but they are just macromolecules right?

Such resilience and academic prowess, I salute your efforts!

[@vipergaming8746]

@@adailyfact I've learnt more about history these past few months. I can share my entire description of World War 2 but it is actually accurate and not just some simple google research thing that takes 5 minutes. Also I meant to say 7th grade, idfk how I've only just touched onto this mistake I made almost technically a year ago. World War 2 was the most brutal and foul war in history yet, it began on September 1 1939, the day when Nazi Germany invaded Poland, just 2 days later Great Britain and France declared war on Nazi Germany for their actions, Hitler never expected a war, although his plans were to rid the world of Jews and other minorities he deemed guilty of causing the collapse of his beautiful Germany after WW1 and because he believed that those such as Polish people were responsible for it. Although the shelling of a Polish garrison at Westerplatte, is believed to be the first shots fired of WW2. There were many leaders. Allies: Winston Churchill (Former Prime Minister of England) Franklin D.Roosevert (32nd president of the USA), and Joseph Stalin (Dictator of the Soviet Union) Axis Powers: Adolf Hitler, Benito Mussolini and Hirohito. (Nazi Germany, Imperalism Japan and Fascist Italy) They all fought against each other for all these 6 years of terror, dread, pain, suffering and agony. Major events such as Pearl Harbour bombing on December 7 1941, and soon later on in 1945, the USA finally got their desired revenge and bombed Hiroshima, Japan around 2 times on August 6 1945, D-Day was the LARGEST and most brutal battle in history, involving the British, French, Germans, Americans etc. It was all a brutal fate they met for their own sacrifices, not to mention the infamous date April 30 1945, Adolf Hitler had finally accepted defeat and committed suicide or probably fled to somewhere to live out the rest of his days until he died due to the SovIet Union having stormed Germany, Berlin. He couldn't take it, so Germany restored back to its original state after a few years. Although with the 2 Joseph Stalin and Franklin.D Roosevert, Captalism vs Communism was becoming major, and which lead to the Cold War.

All living things were created as they are. With all due respect, no such thing as a common ancestor. Living things are so phenomenally intellectual deigns and combinations of scientific and mathematical facts that it is absolutely impossible for such a diversity to come to existence simply by random, unsupervised, wilful, out of no where, overtime, I feel like it kinda change. I really wish intelligent people like scientists wouldn't be so oblivious of this basic concept. I really wish the government and other platforms would stop brainwashing everyone about this in their text just as an agenda to popularise atheism. I really wish this idea is not endorsed. Great video, but the idea of the unknown common ancestor is such an unreasonable idea to popularise and endorse. of course this is a huge agenda funded by the government like how they're desperately trying to brainwash everyone into thinking how miserable Russia has made Ukraine as if there is nothing else of similar or larger scale going on in this world for years on end and endlessly which they are purposely as usual acting oblivious to. intelligent people with a bit of self respect really need to stop saying such absurd things and A level biology will still be just as good.

[@Cloudey-puffo]

Your concept of all beings were created as they were creates large plot wholes not just in biolagy but in similar branches aswell all beings have a similar relaitonship and was created from several (or more) branches ahead of what we called the common ansestor its basic evoulotion wich is found in molecular biolagy "all living organisms were desended from a common ancestor" the presumed last common ancestor of eukaryotes branched of the presumed last common ancestor of all extant organism's the last common ancestor of all extant organism's branched of into Bacteria Thermus, cyanobacteria, Thermotogales and much more even organells wich were in the cell mitochondria and chloroplasts the presumed last common ancestor of eukaryotes branched off into Archaea and Eukaryotas crenarchaeota, korachaeota and much more the thereoy of evoulotion states that us animal, plants and fungi branched of by the first organisms wich were existint on earth (after its own creation from materials rovolving around the sun) the chemoatotrophs the first organism then branched into are known cellular organisms wich then formed into humans this means all living beings have a similar relaitonship and common ansestors exist by the stand of are knowledge i hope you understand
