I have this exam for my birthday 😭 what an amazing gift. Could be a worse exam to have though. Feeling pretty good for paper 2 though! Good luck everyone
I had biology paper 1 on my birthday and i also had a geography paper
happy birthday for tomorrow and hope your exam goes well 🫶🏻
Happy birthday for tomorrow! Best of luck!
Happy birthday for tomorrow and Good luck !!
happy birthday for me and you tomorrow!
Love the video! Just with the practice questions some of them are on topics that aren’t assessed so to everyone make sure to look at advanced info for this year as well!
Oh yes, that's a very good point I forgot to mention! Definitely use the advanced info and ignore anything that you know you won't be tested on!
I'd recommend going over the topics that aren't included quickly because AQA tend to lie
@@Roxhee then the marks will just be removed
This is so sweet! Thank you so much for helping us all, it’s really appreciated :)
1q ) Fungi and bacteria
2) not accessed on Aqa
3) not accessed
4) mitosis is for replacement of dead cells where as meiosis is for reproduction
Mitosis forms genetically identical copies where as meiosis form genetically different copies
Mitosis form 2 copies . Meiosis forms 4 copies
Q5) Phosphate base attached to a sugar molecule attached to a base
Hydrogen bonds
Polymers
Q6) idk
only two tips
Q4) try not to mention ‘copies’, instead say ‘daughter cells’,
Q5) mention the A T C G bases and the complimentary pairs
i’m sure u know that tho, good luck! :)
Nice answers!
@@joshuahutton thank you !
1) Bacteria Fungi 4) Meoisis genetically different offspring whereas mitosis is identically the same.
Meiosis There is variation in the offspring. Mitosis there isnt.
Meiosis has two parents whereas mitosis only has one.
what do you mean by meiosis having "two parents" surely you would say meiosis has two cell divisions whereas mitosis only has one
only tip is to specify that they are ‘genetically’ identical not just identical but i’m sure u know that :)
@@ethannhuntt meiosis has 2 parent cells because it’s coming from both the male and female (sperm + egg) whereas mitosis has 1 parent cell since it’s clones
~ hope this answered your question :)
Good advice!
@@justchillin566 i think instead you would say that it enables two parents to reproduce- meiosis still starts with one parent cell with a diploid set of chromosomes (i'm talking about the actual cell division, not sexual reproduction)
honestly, i can't thank you enough for this video, it was so helpful and informative.
Glad it was helpful! Goodluck!
Literally my favorite channel 🙌
Thanks Jaden! i really needed this
Hope it went well!
plan on revising the main focus but also the older topics that are low tarriffs so i don’t loose easy marks. gonna do you blurting diagrams for the required practicals and fo last paper questions. gonna practice my 6 and 4 marker timing as well. currently watching your video on my way home. doing a 5 hour revision session before bed .
Goodluck! That sounds like a lot!
Thank you :)
thank you !! this is good motivation tbf thank u
I'm glad it was helpful!
thanks Jaden!
Thanks for watching
thank you so much for this video omg
No problem, glad it helped and goodluck!
My gosh Jaden, just coming back to tell you: Your practice questions made me look up biodiversity last night and it really did come straight up in my 2BR today😭😭 thanku
Wow, I'm so glad to hear that it actually came up! Well done!
You're so encouraging! I'm worried about science exams, since biology is the only subgject that will pull my grade (I totally failed physics and chemistry). Thank you for the tips^^
Goodluck, no problem!
@@JadenYee thank you :) I'll need it
Thank you!!!
You're welcome! Goodluck!
i have my last combined combined paper tomorrow. i’m so glad i’ll be done with GCSE science soon lmao i’m so tired
Goodluck!
Thanks yuuu!!!
Wish I did AQA Biology, I’m doing Edexcel and the questions are so much harder
Fr
Goodluck, tell me how it goes!
@@JadenYee Thank You, I’ve done lots of revision today, hopefully it will pay off in the exam 👍
@@JadenYee it went really well I think thank you
1. Bacteria and Fungi
2. Cerebral Cortex
3.The eyeball is too short so light focuses behind the retina.
4. Meiosis involves 2 cell divisions. 4 genetically different daughter cells are produced rather than 2 identical ones. No genetic variation in mitosis.
5. A nucleotide is made up of a base binded to a sugar and phosphate. Attraction between the bases keeps the structure together.
6. More land is being used for farming to increase food production in order to meet the rising demand. Farms are being expanded to increase their output and increasing land results in the loss of natural habitats and ecosystems which reduces the range of different populations in the area.
Not sure about question 5 and 6. I know 2,3 aren't coming up, but I don't trust the advanced information anymore...
is this aqa? cuz i do edexcel
Nice answers!
Yes this is AQA
Where do u get this info from i dont have this in my textbooks btw i am doing aqa
1) fungi and bacteria cause decay
2) frontal lobe is the part of the brain that makes decisions
3) long-sighted people have difficulty seeing objects as their occipital lobe has been damaged? (not sure if this even answered the question)
4) mitosis has 1 parent cell, mitosis is asexual, meiosis occurs in plants and humans only
5) haven’t leant this yet
6) not sure why more land is being used, but farming has decreased biodiversity because of all the deforestation that’s happened to make land for the farm(ing to happen)
Nice answers! Here is the markscheme for Q6
Human Land Use
• increasing population requires more food
• crops / livestock for food
• farming crops for biofuels
• peat use as compost
• peat use as fuel
• increased use of pesticide / insecticide / herbicide / fertilisers
• use of free-range / organic methods increases land use (for
same yield)
Link to Biodiversity
• deforestation
• monocultures
• loss of hedgerows (to make fields larger)
• loss of habitat
• consequence of loss of habitat eg (change in) migration
• fertiliser run off polluting water
• use of pesticide / insecticide / herbicide reduces insects / plants
which damages food chains
• more soil erosion
Link to Atmospheric Pollution
• more carbon dioxide (from farm animals / machinery)
• more methane (from cows)
• climate change or global warming
• example of impact on biodiversity
• acid rain
• desertification
ayy thank you jaden!
6:06 I don't have the slightest clue on this one. Have to look it up.
No problem, hope it went well
@@JadenYee it did. Thanks
i just finished my paper and it went amazing
So glad to hear!
@@JadenYee thank you very much
Nice
A nucleotide is a mono more that holds phosphate groups, 5 carbon sugar and nitrogenous bases. 4 nitrogenous bases in dna are adenine, guanine, thymine, cystosine. In rna the thymine is replaced with a uracil base. This is what makes up living things.
Nice answer!
i hope this is more than we need to know
thats a level is it not
bruh that’s a level
What time is a good time to go to bed? Do you think 10 or 10:30 is okay
mitosis is were 2 identical daughter cells split and its apart of the asexual reproduction as miosis is where it splits into 4 daughter cells which start from the parent cells which are non identical
Nice answer!
i have absolutely no clue what i'm doing and i have the seperates higher paper so yolo wish me luck
Goodluck!
Hi, thank you for the video, it was really helpful! I have a question: what happens if you do badly in paper 1 but you do better in paper 2? Could I get like a 5/6 as my first grade but 8/9 as my second? (I do combined) thanks!
I assume they would average out although not 100% about combined
watching this 2 hours before the exam :,)
Hope it went well!
6:09 The easiest question by far.
More land is being used for farming because more people are being born, increasing the population and therefore, increasing more food demands.
Another way more land is being used for farming because more and more people are eating more, which also increases food demands.
And in return, this decreased biodiversity because we have to chop down more trees for room to farm, and in the process, it destroyed habitats for many animals and killing them in the process, making it less diverse.
Nice answer!
@@JadenYee thanks
paper was great!!
Good to hear!
@@JadenYee thank you. could you do a “last minute tips” video for chem and physics?
@@victoriakorlewalawhat did u get ?
Fungi, bacteria. Then nucleotides consist of deoxyribose sugar/ribose sugar, phosphate group and nitrogenous base. Rest of them rn't in my syllabus.
Oh and also Mitosis produces 2 daughter cells but meiosis 4.mitosis produces cells that genetically dentical to the mother cell but in meiosis it produces cells with genetic variation. Mitosis produces diploid nucleus cells but meiosis haploid.
Nice answers!
@@JadenYee btw I gave my exams a few hrs back. Thnx to u I did rlly good.
My exam is in 7 hours 🥲
GCSE biology paper 2 was harder than I was expected at least in triple higher tier. Most of the questions was AO2 and 3
Check out my new chemistry video if this one helped!
@@JadenYee I checked already
I did everything you said now I am working on questions
Hey Jaden. Sorry this isn't related to this vidoe but I have a question about studying dentistry. Do you think doing combined science rather than triple will make it harder to do anything medicine related?
if you want to do dentistry is there a reason you don’t want to do triple? if that’s your goal i can’t see why doing different subjects would take priority if they’re not what you wanna go into
@@pepsimann2038 nah man i didn't know what i wanted to do so i didn't pick triple. i tried swapping this year but i'm in year 11 and my teachers said its too late. anyways almost done with gcse's and i already picked the a levels I want just wanted to know if not doing triple would restrict me from things.
It doesn't really matter what you take for GCSEs as long as you can do atleast 1/2 sciences at A-level or another alternative exam. Most dentistry universities actually require chemistry but some require others such as biology so make sure to check this out on uni course requirements when selecting your subjects!
Please make videos like this for chemistry and physics paper 2 😭
I will try!
Jaden: "Hopefully you are watching this video few days before the exam"
Me 18hrs before the exam: Well fuc--
Better late than never! Goodluck!
i remember watching this last year haha and i did actually ended up getting a 9 in biology, my problem now is the ucat :(
Oh wow congratulations! The ucat is sooo tough I can understand the pain :( goodluck on preparing for it, it will be worth it in the end
What did u do ?
6:58 One difference between Mitosis And Meosis is that Mitosis only do sex cells whist Meosis does the rest of the body.
Another difference is that Mitosis will produce two daughter cells which are the same whist Meosis produce different cells.
And finally, Meosis happens more often then Mitosis.
You may have got them the other way round in the first sentence!
@@JadenYee So I got the question wrong?
thanks for the vid! is seneca learning helpful for bio?
Yes, it is!
No good nights sleep here it’s 2 am 😅
legend
biology paper 2 mocks tomo wish me luck
question 4:
3 differences between mitosis and meiosis
mitosis is asexual reproduction meiosis is sexual reproduction
mitosis produced 2 identical daughter cells (haploid) meiosis produces 4 daughter cells (diploid)
mitosis are genetically identical?? only question i can answer 😃
Mitosis to replace cells meiosis
is for reproduction .
correct apart from haploid and diploid switched round
I believe for the 3rd point afterdna replicates in mitosis and meiosis
Mitosis are generically identical whereas meiosis the gametes are genetically different.
All good feedback!
@@krumdg1446 i didn’t know that thankyou hahah
omg I wanted to do dentistry in uni when i'm older I didn't realise you did it lmao how is it?
It's good but hard work. There is a lot of content and for us it is very science based in year 1 with not as much practical work as you would think. It is already quite interesting but I'm sure it will be better as we see patients as early as Year 2!
I'm not sure if I've got something wrong but all the topics you spoke about in the practice q's are for paper 1??
The topics I spoke about are Paper 2 GCSE Biology for AQA specifically but a lot of the exam boards will be similar so not sure about yours
@@JadenYee the first 4 questions are paper 1 only for Edexcel...
@@ganeshmullaparthi5201 Oh well spotted then!
can someone pls reply I'm so confused do we need to know mitosis or mitosis for biology paper 2 combined ???
Both I think?
exams in 2 hours
dw have done stuff days before
there isn't much content this year though, there are only 5 not very big topics on paper 2
Thats good news!
for the 6 marker i have 3 points for decreasing biodiversity
-fish farming
-deforestation
- monocrops
but for reasons why more land is being used i can only think of one point
-increased population size
dose anyone has 2 more points i can use????
Here is the markscheme!
Human Land Use
• increasing population requires more food
• crops / livestock for food
• farming crops for biofuels
• peat use as compost
• peat use as fuel
• increased use of pesticide / insecticide / herbicide / fertilisers

@@JadenYee thank you so much
are mitosis and meiosis coming up for aqa combined paper 2?
Not sure about combined, search up exactly what you want to know
watching this at 1am lolll
Hope the exam went well!
@@JadenYee Went Well Thank You!
1) bacteria and fungi
2) not in advance info
3) not in advance info
4) - mitosis involves one cell division whereas meiosis involves two
-mitosis produces genetically identical cells whereas meiosis produces genetically varied cells
-cells produced by mitosis have a diploid set of chromosomes whereas cells produced by meiosis have a haploid set of chromosomes
5) contains a base of either A,T,C or G- A pairs to T, C pairs to G. Attached to a deoxyribose sugar, and a phosphate group which forms part of the DNA's double helix backbone.
a monomer which bonds to others to form a polymer
Nice answers!
1) bacteria, fungus
4)mitosis uses asexual reproduction whereas meiosis used sexual reproduction
meiosis replicates into 4 daughter cells whereas mitosis replicates into 2 identical daughter cells
6) More land is being used for farming because there is an increase in demand for crops. this leads to more space used up
Increased farming reduces biodiversity as it destroys the the different species due to destruction of their habitats in hope for gaining land to farm.
Nice answers!
Any tips for foundation as questions are easier
Everything mentioned would also apply to foundation!
More land is being used for farming due to the constant growing farming industry with lots more space needed to provide livestock and plants with space to grow. Additional space is achieved using methods such as deforestation, this leads to destruction/loss of habitat and perhaps resulting in death/decrease of a species that is reliant on the ecosystem that has been destroyed for more space. This is significant because not only does it decrease the population of a species reliant on the ecosystem- but also affects the species that depend on other animals as a food source. If enough animals die due to loss of habitat, this may result in depletion of food sources for even tertiary predators- further reducing biodiversity.

no comments?
Um I’m sorry but what curriculum is this? I’m studying for my igcse Pearson edexcel exams and I have the exam tmr 😭😭 plzzzz give me advice anybody istg
The advice was for all exam board pretty much, hope the exam was okay!
Hang on it’s on 17th of June for me?
You have extra days to study then!
1 hour before the exam….
What if you are struggling with required practicals
Then I would suggest doing practice questions on all the required practicals and making sure you understand them all! If you look over on physics and maths tutor, I remember that they had a lot of practice questions for practicals. You can also watch videos on practicals on youtube so be sure to use whatever is available to you!
if youre struggling with practicals, go to free science lessons and cover the 2 required practical that are on the exam board website on the advanced info page. As you watch the vid make notes about how you do the experiments and the results. After do some practise questions in it, form physics math tutor or even save my exams.
if you're struggling to understand a practical, look up a video of someone doing it and then try to draw it out on a scrap paper - also physics and maths tutor has the control variables you need to know and the risks, so i'd recommend learning those for each practical as usually a question could ask 'describe 2 things that the student should keep the same' or something like that - good luck, hope this helps! (btw i am doing edexcel GCSE and i know pearson make youtube videos on each practical so check the exam boards youtube)
First go through the method for sampling
Freesciencelessons. I just watched his vids and made flash cards from it ( you don’t have time for flash cards so it’s not worth it! )and I got easy 9
1. Bacteria and fungi
2. (I'm combined so i dont think i should know this)
3. ^^
4. Mitosis results in two daughter cells being made whereas meiosis results in 4 daughter cells
Mitosis' daughter cells are identical whereas meiosis' cells are different
Mitosis is an example of asexual reproduction (one parent. Usually involved in some animals or skin repair and growth) whereas meiosis is sexual reproduction so has 2 parents.
5.(combined)
Rest i cant answer as im not triple
Nice answers!
Im kinda sad they took out ALL of evolution and variation and the development of genes…that was quite an interesting part of biology and it’ll be hard in a-level im guessing😩
Yes I always enjoy that topic! It was actually quite similar for AQA biology for A-level!
5:36: Bacteria
Fungus
Nice!
@@JadenYee thanks
Few days before * 1 hour ago 😫😭
Very last minute!
@@JadenYee thank you for your advice though very much appreciated! Hope dental school is going well !
how did you know💀
last minute? i’m just starting to revise
Goodluck don't worry just try your best!
Just try to remember the practicals (especially the one with the quadrats) and also make sure you try to remember most of the content ( I would recommend freesciencelessons or primrosekitten, but ima be fr freesciencelessons is better). I got a grade 9 in my paper 2 mocks by doing this the day before
@@gutso5749TIPS FOR ME PLEASE 😭😭
