thank you please do some exam style too and maths thanks

[@tehreemnadeem3698]

ok, its an awesome video but maybe for future videos try to edit the parts where you are writer a little faster as I found my self just sitting there waiting for you to finish writing it which made me get really bored. And I also had to speed up the video. It's an awesome video though. really helpful.

Hi miss,I just wanted to ask you I have been revising for maths but I feel like it's still not enough and I'm so worried because I don't want to retake maths and I just want to know do I still have time to pass because I'm currently a 3 and I keep having nightmares of retaking it and I don't want to.Thank you for your videos and the time is just going so fast 😭😭😭

[@imraj9018]

Hello, could you please make some videos (even if it's just 1-2) on OCR 21st century science, it would be super helpful if you could, thanks.

Hi, could you say that the sex gametes are ovaries and testes rather than eggs and sperm in answer ?

[@Primrose_Kitten]

no, they are not the gametes, but rather were they are produced

[@zainghafoor6532]

Science and Maths by Primrose Kitten Oh I see, thanks!

Thanks a lot

Just wondering if the genotype ‘ff’ means that the person has cystic fibrosis? It says ‘ff’ in the video is normal but my revision guide says ‘ff’ is an affected ( with the disease) child🙈 please help!!!!

[@Zara-hu7bb]

Zara Adam because cystic fibrosis is a recessive gene, I’m pretty sure ‘ff’ is a cystic fibrosis suffer

[@zara-amaniadam3693]

Zara Davies i thought so!! thank you

For practicals can u plz tell us why we put those things because in exams they always ask us questions like why did u put iced ethanol in? Tnxs

[@grrrmondays4587]

To make the DNA clump together

[@unknown-4590]

too extract the dna

[@khaxxx433]

iced ethanol is used because DNA is insoluble in that which is why it appears as a white stringy precipitate. Salt is added to clump DNA together and Detergent is added to break down the cell membrane so DNA is relaeased.

[@Drakmord666]

Hey, just to say the non coding is not junkDNA it's the instruction book for the codingDNA
