This course is designed to help you revise for GCSE Biology paper 2. The principal topics of interest are homeostasis & response, inheritance, variation & evolution and ecology. There are quizzes at the end of each section to test your knowledge.
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.
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.
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.
Ecology concerns the interaction of living organisms, both with each other and within the landscapes they inhabit. This diagram provides an introduction to the study of ecologies and factors which can alter their habitats.
Let's take a more detailed look at ecology and the terms we will encounter. In any food web there are producers and consumers. Some organisms are the primary consumer while others scavenge the remains. Learn more here.
Ecology is a wide ranging topic, so we present a bigger quiz to help you understand this subject. Questions are mostly multiple choice and true-or-false. Aim for a score of 80% or higher. Best of luck.
