WJEC GCSE Biology revision

WJEC GCSE Biology revision for Year 10 and Year 11, following the WJEC GCSE in Biology (Wales) (3400QS) specification point by point. WJEC GCSE in Biology (Wales) (3400QS) covers Cells and organ systems (Unit 1), Ecosystems and biodiversity (Unit 1), Variation, inheritance and evolution (Unit 2), Homeostasis and response (Unit 2), Micro-organisms, disease and biotechnology (Unit 2), Practical and scientific skills (Unit 3 + AO3). Short interactive activities first, then a real past paper: the activities teach it, the paper tests it.

One thing the Biology questions here are written to catch: A cycle closes because the atoms return; that is the reason for the shape.
