IB Biology — Complete Revision Guide

A comprehensive, exam-focused revision guide covering the full IB Biology syllabus: cell theory and ultrastructure, biological molecules and enzymes, genetics and pedigree analysis, DNA/biotechnology (PCR, gel electrophoresis), cell respiration and photosynthesis with limiting factors, ecology and energy pyramids, evolution and cladistics/convergent evolution, human physiology and immunology, the “Nature of Science” theme, and IA statistical analysis guidance. Includes a custom ecological energy pyramid diagram, fully worked examples (pedigree chart diagnosis, limiting factor identification, vaccination/immunological memory explanation), comparison tables addressing frequently confused IB Biology concepts, a 9-term glossary, and original practice questions with detailed explanations. Built around the mechanism-to-significance connections and Nature of Science integration the IB specifically rewards.
