  • Month Administered: July 2026
  • Duration: 2 Hours
  • Total Marks: 80 Marks
  • Number of Questions: 28 Questions (Questions 1 – 28)
  • Structure: Single compulsory paper containing 28 structured questions

  It covers the following topics:

  • Skeletal systems in animals and Chordata taxonomy (notochord presence)
  • Plant histology (aerenchyma tissue adaptations) and cell organelle functions (nucleolus, nuclear pores, lysosomes)
  • Nervous coordination (motor neurone structure and functions) and phloem tissue adaptations
  • Evolutionary mechanisms (vestigial organs in humans and drug resistance as natural selection)
  • Digestion and biochemistry (salivary glands/saliva roles, catalase activity, enzyme inactivation)
  • Respiration experiments (germinating peas respiration set-up with KOH and lime water)
  • Excretion and osmoregulation (diabetes mellitus vs. insipidus, nephron distal tubule reabsorption, nitrogenous wastes in urine)
  • Ecological concepts (synecology, carrying capacity, population, aquatic productivity depth gradient)
  • Plant water relations (sunken stomata and transpiration control)
  • Surface area to volume ratio in relation to body size and transport system complexity
  • Taxonomy (salient features of Class Aves) and mammalian osteology (scapula anatomy and articulation)
  • Comparative renal physiology (desert mammal vs. freshwater fish glomeruli) and eye anatomy (choroid functions)
  • Microscopy (biological drawing magnification calculations) and genetics (sex-linked inheritance of haemophilia)
  • Gaseous exchange adaptations (tracheal cartilages and alveolar surface area)
  • Growth and development (intermittent growth curves in arthropods, ecdysis, seed dormancy causes)
  • Reproduction (male reproductive anatomy: epididymis, prostate gland, scrotum) and cerebrum functions
  • Biotechnology (industrial applications of anaerobic respiration)
