GCSE Biology Paper 2

This Mind Map depicts the systems which are involved in regulating the functions of the body. The brain, the nervous system and the glands work in concert to keep your internal workings at a steady rate.

All important information from the AQA GCSE Biology Revision Guide on topic Homeostasis and Response.

These flashcards will help in your understanding of how the body maintains a stable inner environment. Among the chemical compounds your body produces are insulin, adrenaline and testosterone.

Here is a short quiz to test your knowledge of the processes of homeostasis. There are eight questions presented in a number of formats including drag-and-drop and fill-in-the-blank. Complete this test and move on.

Drag and drop activity about homeostasis

Here is everything you'll need to know about DNA, Chromosones, Meiosis, Variation, Inheritance, Evolution and more. These notes cover all the basics and topics are kept short and bulleted to aid memory.

Now it's time to take a short quiz to review what we have learned about genetics and the branches of inheritance, variation and evolution. There are only seven questions, so aim for a high score. Good luck.
