Homeostasis is the maintenance of a stable internal environment

This 9 page revision resource covers the WHOLE of section 3.6.4 from the AQA Alevel Biology Specification: 3.6.4 Homeostasis is the maintenance of a stable internal environment, which includes the topics “Principles of homeostasis and negative feedback”, “Control of blood glucose concentration” and “Control of blood water potential.”
The purple bullet points are copied directly from the AQA spec, with my own notes directly below each point to ensure that every aspect of the spec is covered. This is one of the larger topics in the AQA specification and have come up every single year since the new spec was put into place so is a topic you really need to grasp thoroughly! Within this resource are “Key Info” text boxes containing essential key words and facts needed in order to achieve marks on the super specific AQA markscheme! I spent hours on this revision pack so hope you enjoy it too!
