HIGHER BIOLOGY COURSE NOTES (Leckie) - Tapa blanda

This title is designed to provide an overview of the whole of the Higher Biology National Qualification and deliver a focused course approach to compound student knowledge and understanding of key processes and functions.

Comprehensive notes in this handy slim-line edition cover Cell Biology, Genetics, Evolution and Adaptation and Control and Regulation in three distinct units. Extensive diagrams and accessible, clearly presented explanations support student understanding and help students in the revision process to feel confident of their subject knowledge.
