COMPLETE: 3.6 Organisms respond to changes in their internal and external environments

These topics come up every single year without fail. This bundle contains revision notes on ALL of the 3.6 section of the AQA Alevel Biology specification including:
3.6.1 Stimuli, both internal and external, are detected and lead to a response
3.6.2 Nervous coordination
3.6.3 Skeletal muscles are stimulated to contract by nerves and act as effectors
3.6.4 Homeostasis is the maintenance of a stable internal environment
I used these notes to achieve top marks in my Biology A level and hope they will help you too!
