OverviewExcellence in Biology Level 3 has been fully updated to take the realignment of Level 3 Biology into account. This resource has a highly visual approach and presentation. Hundreds of specially drawn illustrations, all in full colour, help students to understand biological concepts. The text includes comprehensive coverage of external NCEA Level 3 Achievement Standards and also the internally-assessed 'How animals maintain a stable internal environment' and 'Human manipulation of genetic material and its biological implications'. The content is biologically accurate and rigorous, and maximum priority is given to linking concepts. Each chapter concludes with a summary of essential facts and ideas, and a quick self-test of basics. Extension material is also provided for deeper understanding.
