The spec says we need to know 'The role of helper T cells (TH cells) in stimulating cytotoxic T cells (TC cells), B cells and phagocytes. The role of other T cells is not required.' Does this mean we don't need to know in detail how cytotoxic t-cells work (41:11)? Its also not in the CGP book.
Literally love your work! I'm a new A levels student and i felt really tensed seeing most of the materials for biology which were really hard to absorb and understand. This video definitely gave me motivation to grind harder. LOTS OF LOVE ❤
Hello, really these videos are very helpful for my revision. They're very easy to understand. Is it possible for you to create a playlist for each A level paper with the topics just mentioned on the Advanced Information topics list? Anyways, thank you very much for these videos, I've also got your notes for year 1 and 2.
Hey, So glad you like this series. Really hope you're finding the notes useful too. Once I've finished this series, then yes I will be making a WHOLE PAPER 1 and Paer 2 video based on the topic lists 😀
As b-cells undergo endocytosis and present the antigens on their cell surface membrane wouldn't the b cells also be counted as 'antigen presenting cells' like phagocytes?
Hello Miss, truly a fantastic and helpful video. I just wanted to ask however if you don't mind, would it be possible to increase the quality of these videos or not as I am only able to view it at 480p.
Hi, I was just a bit confused about the terminology in mitosis with chromosomes and chromatids. So at the start, in prophase, do we say that chromatin condenses to form chromosomes and then sister chromatids are pulled apart in telophase to form chromosomes? Basically, is the chromosome the pair of sister chromatids or just one chromatid :)
Check your specifcation online, type in your exam board and the course you are doing and check the specification, which should tell you whether you need to know it or not.
Could you make a video on all the new spec changes in one? might be a hard video to make its just immunity and stuff liek that we dont need to know anymore
How similar is the AQA specification to OCR? I would love to watch your videos but just want to be sure that I would be learning the right content for my spec :-)
hello i wanted to know do we revise the whole spec or only the topics on the advanced spec and the topics interlinked to the topics on the advancedd list. please bare in mind i want to get A's
I use the advance spec as the areas that I need to know inside out, what's not on the spec is what just needs to be consolidated from time to time. Most of the Biology Paper is however application based, so having a solid subject knowledge is key - next is picking apart the questions. When doing practice questions identify which topic the question comes from, what keywords you can relate to said topic and the question, use these to formulate your answer. (Just a tip, haha) 😄
Does the phospholipid bilayer in the cell plasma membrane prevent soluble watery substances from entering the cell? So that it does not affect the water potential and cause damage through osmosis (make the cell burst or dry up)?

Yea, Jesus Im revising like 4 hours before the exam. Good luck
Thank you , i was lost where to start in A level biology you're yt channel helped me alot .
ahh I'm so pleased it's helped ! It is a bit of a jump from GCSE

Sometimes its good to learn additional information which is off the spec for the essay.

Hey!! Welcome to A-level Biology, it's awesome 😁😁 I have loads of videos and resources so you'll have lots to support you

Hey, yes they can be! ☺️
thank you so much these are great!
You're welcome and so pleased they help!

IK! I think Miss Estruch should do skincare and haircare videos
Hi how similar is the aqa spec to the edexcel spec? We use edexcel and I'm struggling so much to find good biology channels that use the edexcel spec.
Hello Miss, truly a fantastic and helpful video. I just wanted to ask however if you don't mind, would it be possible to increase the quality of these videos or not as I am only able to view it at 480p.
Yeah i need to work out how 🤔 Think I may have to look into a different program to record with!
Hi miss. I was wondering if you had a video on membrane permability and the effect of temperature on phospholipid billayer ?
hey, it's in my required practicals playlist

Hello miss, thank you very much for the video. I was just wondering what happened to the antigens that are presented by the b cells?
How do you know whether to talk about humoral or cell-mediated response in exam?
Im doing edexcel a level biology but i really love your videos. Is there any difference between aqa or edexcel?
Could you make a video on all the new spec changes in one? might be a hard video to make its just immunity and stuff liek that we dont need to know anymore
U do need to know for paper 3 essays
Thank you !! it's rlly helpful, just wondering if u don't mind will you be able to post a video of only the practicel skill and required practicals ?
Hey so pleased it helped! Yes I will be doing just that. Probably coming in a month
do we need to know the colourimeter practical?

Is the plasma membrane within the phospholipid bilayer e.g. channel and carrier proteins, cholesterol or is it completely different?
the phospholipid bilayer is within the plasma membrane

Does the phospholipid bilayer in the cell plasma membrane prevent soluble watery substances from entering the cell? So that it does not affect the water potential and cause damage through osmosis (make the cell burst or dry up)?
It prevents water soluble substances from diffusing because they're polar
do I have to know about the types of vaccination like live-attenuated and inactivated as well as smallpox?
Not for AQA
@@MissEstruchBiology okay thanks
i love you miss.
For AQA A-Level, do we have to know about the resting stage G0 in mitosis?
nope, not for AQA
Yes , it’s apparently a part of beyond the spec and can be used in paper 3 essay ig
