The content of the first volume of Biology for the third year of high school Health Studies offers students the opportunity to discover a part of the magic of the natural world, the functioning of organisms, their interactions in ecosystems, and the evolution of organisms.
Writing an educational book for this particular subject is a challenge for any author, who must constantly combine the simplification of concepts and phenomena with the maintenance of scientific style and the search for tactics that will contribute to sharpening students' interest and, above all, their effectiveness in exams.

Each section of the book contains:
- Combined questions with answers, covering the entire exam syllabus
- Methodology for combined exercises
- Model solved exercises with full justification
- Review exercises of graded difficulty, divided into topics A, B, C, and D, as in the National Exams
- Answers to all exercises
