If you’d like to practise the material covered in this video, check out our platform at www.cognitoedu.org - it's totally free, and has been built to make learning and revision as easy as possible. The main features are: - Lessons organised by topic, only the lessons relevant to your specific exam board and tier are shown. - Automatic progress tracking. Progress bars tell you what you’re doing well at, and what you need to spend some time on. - Practise quizzes so you can test your knowledge. You can quiz yourself on any combination of topics you like. - A huge number of fully-hinted questions that take you step-by-step through some of the trickiest calculations & concepts. - A comprehensive bank of past exam papers, organised both by year, and also by topic.

Thank you so much. It’s confirmed that your gonna be very, very, successful. Thank you so much for teaching us for free and providing links to past papers. We are very,very thankful and grateful ,
@@lollmaohahaha I'm pretty sure the subatomic particles can be separated, but it's unlikely to happen on a large enough scale and for long enough to ever make cause a deficit in atoms for us. But I think they can be created and destroyed; that's energy you're thinking of
@Cognito Do you think this would be a correct explanation for the C cycle, and should I correct or add something? “In photosynthesis plants absorb carbon in the form of CO2 from the air. This carbon is then transferred to the form of glucose, from which respiration can be done by the plant, hence returning C atoms back into the air as CO2, or the C atom in the glucose can be used to synthesise other C-atom-contacting molecules such as carbohydrates, lipids or proteins, and become part of the plant’s biomass. The plant my then be eaten. Thus C-atoms from the plant’s biomass are transferred to the animal: some of which will be returned to the air in CO2, some will become part of the animal’s biomass, and some will be lost in waste such as faeces, or the animal’s dead body. The plant/animal’s dead body will then be decomposed by decomposers, who will respire, using the C-atoms from the animal’s biomass, returning C-atoms back into the air for plants to photosynthesise with. However, some dead animal/plant biomass may be in conditions that don’t allow decomposition to occur, such as a lack of O2. Thus, the biomass and waste will over millions of years of high pressure and heat will become fossil fuels. They can be then combusted and hence the C-atoms would be returned to the air and the cycle will repeat.” Thanks!!!
