23:02' there's another trick to avoid this while using the same syringe it is by taking the lowest concentration first and then work your way up to the highest, e.g I take 0.001% first, then 0.01%, 0.1%,1% and lastly the highest 10% in each test tube while using the same syringe

Hi miss, just have a doubt about the syllabus, in the gas exchange system in 2021 we had to learn about smoking and the components of cigarette while in the 2022 they completely removed those so does that mean for students who's about to give the upcoming summer exams doesn't have to worry about smoking and what the components do to the body? Thank you very much!

Yes that's what it means. You don't have to study whatever has been removed from the syllabus

It depends on what they ask in the question. If they don't specify, write in two decimal places
