  "note": "Nine chapters — introduction, solving a biological problem, biodiversity, cells and tissues, cell cycle, enzymes, bioenergetics, nutrition, transport — the same nine, in the same order, as KP's Biology 9, both National Curriculum 2006 books; the preface explains the reduction from an earlier nineteen. A1 3 rests on two adjacent sections in Chapter 1: §1.1.3 Quran and Biology, opening \"The Almighty Allah has conveyed a great knowledge about the origin and characteristics of animals and plants through our Holy Book, the Quran\", and §1.1.4 Contribution of Muslim Scientists — both examined, the latter by the exercise \"Describe the role of Muslim scientists in the field of biology\". Worth noting for comparison: Sindh reads Al-Anbiya 30 materially, symbolising water with protoplasm, where Punjab reads the same verse as common descent. A7 4 despite a low pronoun ratio, because this is the one science book in the corpus that discusses gender as a subject, on cultural preference for men and girls' malnutrition.
