Your videos are absolutely amazing! Of all the A Level biology KZbin videos I find yours stand out above them all - the mentioning of exam technique (we all know how specific the biology ms is) is so useful, and the few questions at the end - honestly the best! I’ve also applied for biological sciences at uni and your videos will massively help me to get that A/A*! Thank you so much :)

[@AlevelBiologyHelp]

Wow thank you so much! Means a lot :)

[@medischanalyse7719]

Starting revision 8 hours before my A2 exam, will be back here on results day to let u know what I got😂 Ur vids are absolutely awesome thank u

[@izaan3953]

what did u gett??

[@Masowe.]

Did you score big or low?

[@Ilovetoomanythings72]

how was it?

[@ahmadbakri8241]

thank you so much for making this. Very nice and organized, and extremely informative.

[@marawrrrii]

you're actually a lifesaver, thank you for this

[@pallavisrikanth9748]

thank you so so much for this! my teacher's are absolutely rubbish and this helped loads

[@AlevelBiologyHelp]

You're so welcome 🥰

hey! just a tip, you shojuld buy a graphics / drawing tablet with which you can write and annotate things on the work board way easier than a mouse. a mouse is very hard to write / draw with. if you don't want to buy a graphics tablet you can try turning down the dpi (sensitivity) of your mouse to a very low one with which you can write with much more accuracy, avoiding mistakes.

[@AlevelBiologyHelp]

Haha I do actually own a graphics tablet now, this was made before I had one though! Thanks for the tip :)

[@nikhilrupal1378]

Great Vid bro, really enjoyed it. Please let me know if any further videos on this a put up!

[@sidrarani6589]

Hi your vids are so use-full But do both of the ER contain a single phospholipid bilayer or does the smooth one only contain it and also how do the 2 different ER interact with one and other and with other organelles in cell. Thanks

[@yusra1429]

Hi, when you mentioned that the dna of a prokaryotic is a single circular molecule and not associated with protein, what do you mean by this?

[@AlevelBiologyHelp]

Hi, this means that DNA in prokaryotic cells is not bound to proteins called histones (that is A2 content). And eukaryotic DNA is a linear double helix whilst prokaryotic DNA is a circular double helix. Hope this helps

[@yusra1429]

@@AlevelBiologyHelp thank you for the reply

[@amberwest1711]

Do your videos cover all the content required or do they just show the basis? :)

[@AlevelBiologyHelp]

They cover all the content :)

[@omaramin4026]

what about binary fission?

[@AlevelBiologyHelp]

Hi, I talk about binary fission in my "Cell Cycle and Mitosis" video. :)

[@hxrmxn2034]

what organelle isletter M than on the first question at 20.19 seconds?

[@AlevelBiologyHelp]

It's pointing to the cytoplasm

[@safandsound]

What did you mean when you said proteins such as sugars and carbohydrates?

[@AlevelBiologyHelp]

Hi! I was saying that proteins can be modified with substances such as sugars and carbohydrates :)

[@safandsound]

@@AlevelBiologyHelp Ohh, I see, thank you!

[@AshBeastFPS]

hii amazing vid but did u mention vesicles?? i didnt hear much on it and dont know if its required knowledge lol

[@AlevelBiologyHelp]

In the exam if you're told to describe the action of a lysosome, you would say that they fuse with a vesicle (which is what contains an engulfed foreign substance/pathogen) and release lysozyme (examiner prefers "hydrolytic enzyme" - you would still get a mark for putting lysozyme).

[@safandsound]

Do we need to know about the capsule relating to the virulence factor?

[@AlevelBiologyHelp]

Hi! You don't need to know about the capsule relating to the virulence factor for AQA A Level. Watch my "Cell recognition and Immune system" video to see what you need to know :)

[@MuhammadAltamashKhattak]

what about centrioles and cytoskeleton etc.

[@AlevelBiologyHelp]

Hi! You don't need to know about those for AQA :)

[@MuhammadAltamashKhattak]

@@AlevelBiologyHelp ohh ok, i study for the CIEs but there aint much difference, AQA just shorter i wish we had that :(
