@@adailyfact use her past paper question packs. I practiced daily when school gave us study leave with the topic focused questions so that once I got used to the mark scheme, I knew how respond to questions in the way that AQA want them to be in.
I’m a bit confused, in the advanced information Required Practical 9 is listed… Should I focus on learning this version (w/ respirometer) or the one involving yeast w/ TTC ?? ☹️
she responded to a question like this on instagram, and mentioned that questions could be asked on either method so its safest to learn both (rough method etc) :)
Hey, why don’t you have to double the calculated volume of the tube to get the actual respiration rate? My thinking is that as the liquid moves towards the experimental tube with lower pressure, the pressure on the other side also decreases due to there being more volume freed up by the moving liquid. This would imply the liquid kinda “stops halfway” when the pressure on either side reaches equilibrium. Or in other words, V_actual is 2x V_measured?
Hello miss. Thanks you so much your video was really useful to me😊 can I ask if whether we could be asked how to find the diameter of the tube to find the area or will it be given to us
It's decreasing the volume on content inside the tube, not the actual size of the tube. So the tube volume is the same, but volume of gas inside of it has decreased which is why the pressure decrease. Hope that helps
Is there a video on how the human gas exchange system is adapted for gas exchange? I seem to only be find the mechanism of breathing (Antagonistic muscles, diaphragm etc).
You’re amazing; thank you so much! I love how the content is broken down very simply and i love the exam questions at the end!

I'm giving a levels in June and I cannot tell you how helpful your videos on practicals are because the textbook explanations makes no sense to me ❤
ah I'm so pleased!!! Good luck 😁😁
Same I have exams starting in 16 days as I do psychology alevel
Your videos help soo much more than my teacher could.
Thanks a lot for this. Really helped 👍
So pleased it's helping 😊
Literally found out last minute that this might be in the paper 2 as well as respiration with yeast and glucose. 😭😭 thank you so much
What grade did you end up getting.
@@adailyfact A* in bio and it’s all because of miss Estruch 🙌🏾
@@michaelNamikaze Wow well done, I have a medical school offer and need AAA. I am predicted 3 A stars - any tips?

what is the name of the color liquid or which indicator can one use for the color liquid? Thanks

HEllo, no I have not seen that before. The piece of apparatus should inform you on purchase the diameter size.
how would you change this practical to measure C02 produced ?
thank you so much!
Thank you so much this is really helpful
so pleased it helped 😀
Hey bro, what course are you applying for?
Thank you so much!. This is really helpful
So pleased it's helped 😁
Wouldn't decreasing the volume increase the pressure in the experimental tube, causing the fluid to move towards the control group?
It's decreasing the volume on content inside the tube, not the actual size of the tube. So the tube volume is the same, but volume of gas inside of it has decreased which is why the pressure decrease.
Hope that helps

@@adailyfact A
@@reece3231 nice nice. What are you doing now and when did you do your A Levels?
@@adailyfact psychology at Warwick university. 2022
is this also for ocr a ?
4:37 shouldnt pressure increase? volume and pressure are inversely related?
the volume of gas is lower inside the same sized chamber (not the volume of the chamber decreasing), so gas pressure decreases
@@MissEstruchBiology ooh got it, thank you!! need to brush up on gas laws 😭
This was amazing!!
Thank you!!!
very helpful, thank you!❤
Hi miss there are 2 videos on this same practical, are they the same?
hey this is the correct one
The other is now unlisted because I made imporements
@@MissEstruchBiology Thank you Miss
What are some sources of errors?
Can you use this for OCR A?
Yep
that's what im doing the morning of the exam lmao

this is required practical 9! Or one option of how required practical 9 could be assessed
@@MissEstruchBiology I did some exam questions and watched your vid so it's all good now. Thank u!

@@adailyfact I got the exact mark needed for an A*, quite lucky
@@BluPlays Wow well done, I want to get an A*, any tips? I have an offer for medicine which is AAA. Do you also do chemistry?
