This is the only part of 4.5.2 which hasn't been removed (triple) but the advanced info says 4.5.2 will be a main area of focus so I think it will be worth knowing everything in this video really well! Thanks for all the hard work sir, I retain and comprehend info from videos a lot better than reading textbooks so I just want to say a massive thank you for spending so much time on helping students
Question sir, Does the 2022 triple playlist contain all the topics coming up in the paper or only the 'main focus' that AQA has provided? Just asking to double check, so that I can easily be prepared for the exam, your videos and workbooks are amazing!
I am a student who missed year 11 because time abroad and now I revised science using cgp books and ur videos.What else should I do to prepare for tomorrows exam other than this playlist
dont bother they dont say shit they probaly failed because you cant just watch his vidoes expecting to know everything you have to work aka memorise turn his notes into flashcards and do exam practice @@felixfaraji08
Do we need to know about enzymes because we were also taught that if body temperature is too cold, enzymes are below optimum temperature so kinetic energy is lower. Enzyme controlled reactions fall far too low and not release enough energy and cells die and vice versa for too hot. Or is this too much detail?
Is it too late/early to start past papers in January for all subjects? Then as i go along to make flash cards on the mark schemes? Do u think this is an effective way to achieve all grade 8/9's????
my brain is learning about itself and the brain worked out the brains things in the scientists brains when researching brains by using their brains thinking about brains
It's because your body temperature increases if you are infected with a virus. That's one way that the body fights off a viral infection as viruses do not replicate efficiently at higher temperatures. But because your body temperature has increased, you then sweat.
Im gonna finish this 2022 playlist tonight, its been an amazing 2 years watching these videos, hope the examwill go as well as paper1
I hope it does and that you get the grades that you want.
good luck 👍
@@Freesciencelessons thank you ive got the exam tomorrow wish me luck
@@Freesciencelessons You have honestly helped me so much this past year, thank you so much for all your videos
Same I’m watching it now we have the exam tomorrow yay
when homeostasis is easy but you're going through the whole playlist just to be safe
lets not say 'easy' exactly ;( but its better than ecology for sure and much much MUUCCHH more interesting than inhertance etc.
same
so true
Asa Tsunami So true lmao. They're everywhere.
Armys are everywhere and i love that
couldn't have actually been explained in any better way!
This has really helped, i feel like i can only learn from a teacher, not by looking in a book, thank you so much

I like the way you say skeletal; kinda goofy :p
wen did he say that lpl
@@natalya5827 2:33
this will be my final day watching your videos, thanks for everything!
Please do these videos for a level!!
Thank you for the videos. What subjects, if any, will you cover at a-level?
hes covering A level Biology and Chemistry
I think you missed out when the hairs in the body stand up to trap a layer of insulating air for too cold??
That's no longer on the AQA spec.
Freesciencelessons Oh,sorry for the misunderstanding.
No problem. A lot of things that used to be on the old spec have been dropped.
If I mention the hairs standing up for homeostasis will I get the mark though?
they are told to accept any valid answers not listed most of the time
2024444444 where are uuuuuuuu
Thank you sir your service has been brilliant and I have learnt loads and I think I'll get brilliant grades thanks to you
do we need to know about how the hairs rise to trap heat with air bubbles under them?
Ues
Yeah same????
Question sir,
Does the 2022 triple playlist contain all the topics coming up in the paper or only the 'main focus' that AQA has provided? Just asking to double check, so that I can easily be prepared for the exam, your videos and workbooks are amazing!
Hi. The 2022 playlists contain only the focus topics. The links in the description tell you what is not examined. All the rest could be on the papers.
@@Freesciencelessons ok, thank you very much for all your support sir
This is surprisingly easy considering its a triple topic
thank u, sir! Very informative video!
Bestest channel
I am a student who missed year 11 because time abroad and now I revised science using cgp books and ur videos.What else should I do to prepare for tomorrows exam other than this playlist
What did u get
Ye I'm curious too, what did u get...
dont bother they dont say shit they probaly failed because you cant just watch his vidoes expecting to know everything you have to work aka memorise turn his notes into flashcards and do exam practice @@felixfaraji08
do i need to know about erector muscles and hair standing up? it isn't on the specification but it is on a few study guides that i've used
it is time to start the grind
Hi sir,
When the sweat evaporates does this take away heat energy?
Thanks
Yes that's correct. This is called latent heat of vaporisation.
@@Freesciencelessons Thanks Sir
Everyone gangsta until free science lessons shows up. Jk, these videos are really helpful. Thanks
im watching this as part of the "Biology Triple Higher Paper 2 2022 Topics" Playlist, is this Edexcel or AQA?
how long till you release your workbooks? will you be able to release them by the start of next year?
The Chemistry 1 workbook is already released. You can find it on my website www.freesciencelessons.co.uk
Do we need to know about enzymes because we were also taught that if body temperature is too cold, enzymes are below optimum temperature so kinetic energy is lower. Enzyme controlled reactions fall far too low and not release enough energy and cells die and vice versa for too hot. Or is this too much detail?
In colder temperatures, the body emits more heat right? So does this system kick in when that happens and the body temperature lowers?
Is it too late/early to start past papers in January for all subjects? Then as i go along to make flash cards on the mark schemes? Do u think this is an effective way to achieve all grade 8/9's????
I DID THAT for RE exam i sat last year - repeated the questions so many times i memorised the mark schemes( got a grade 9).
tutor me fr
Sir, How much detail do we need to know about synapses
do you have a video on the brain?
do we need to know about the thermoregulatory centre being in the hypothalamus?
i learnt it like that so ig js do it to be safe its js one word anyways so i would prolly say that
My saviour
at 1:04 what does it mean to send down sensory neurones?Does it mean through the neuron of the body?
Are flushing and vasodilation the same?
Vasodilation is what happens in the skin to cause flushing. I'd always use the word "vasodilation" rather than flushing in the exam.

tank u.........
2019 studeeeents!!!!
GUYS IM SO SCARED FOR GCSES HELPP
my brain is learning about itself and the brain worked out the brains things in the scientists brains when researching brains by using their brains thinking about brains
brain is a weird word hm
Shuuuuuush
If i get sick why do i sweat
Because your body temperature will be greater than normal (37 degrees) so in this case, your body sweats to cool off.
It's because your body temperature increases if you are infected with a virus. That's one way that the body fights off a viral infection as viruses do not replicate efficiently at higher temperatures. But because your body temperature has increased, you then sweat.
Hi, does the AQA spec change annually?
no.
Mistake at 0:53 - the text calls the thermoregulatory centre the thermoregulator centre.
Sorry yes I see what you mean. Thanks for flagging that up.
shut up
2:41 how does releasing heat mean that the body warms up?
muscle cells release heat IN the body not to the environment so it warms up the internal environment
I’m in year 7
