Written to accompany Salters-Nuffield Advanced Biology (SNAB), an exciting new A Level course. As the only book for this new specification, it's a 'must-have' for all students taking the course. The book looks at Biology through contemporary contexts, boosting students' enthusiasm! Both the course and this book have been piloted in 50 schools and colleges for two years, so Salters-Nuffield Advanced Biology is tried, tested and trusted.
