In this video, I explain ALL of the content required for the "Principles of homeostasis and negative feedback" section for AQA A Level Biology. This includes: what is meant by homeostasis, the need to control temperature, pH + blood glucose concentration and the principles of negative feedback and positive feedback. Time stamps are in the comments.
I also go through a couple of exam questions and explain the mark schemes.
The content in this video crosses over with other exam boards too.
Please leave a comment if you have any questions, I'll be more than happy to answer them!!! :)
