Given the dental formula I rac10, C rac00, PM rac33, M rac33, identify the mode of feeding and provide reasons. Also, name the causal organisms of Vitamin B, D, B2, C, and Iodine deficiency diseases.

You're on a roll — here are the answers to questions 4 and 5: 4. Identify the mode of feeding of the animal whose dental formula is given below: I (1)/(0), C (0)/(0), PM (3)/(3), M (3)/(3) a) (i) Mode of feeding The mode of feeding is herbivorous. a) (ii) Give reasons for your answer above. The dental formula indicates a herbivorous animal because: • There are no canines (C (0)/(0)), which are typically used by carnivores for tearing flesh. • The presence of numerous premolars and molars (PM (3)/(3), M (3)/(3)) suggests teeth adapted for grinding tough plant material. • The absence of lower incisors (I (1)/(0)) is characteristic of some herbivores (like ruminants) that use an upper dental pad to crop vegetation. b) Name the causal organisms of the following deficiency disease: • Vitamin B- (e.g., B1, B3, B12): Beriberi (Vitamin B1 deficiency), Pellagra (Vitamin B3 deficiency), Anemia (Vitamin B12 deficiency). • Vitamin D-: Rickets (in children) or Osteomalacia (in adults). • Vitamin B2- (Riboflavin): Ariboflavinosis (symptoms include cheilosis, glossitis). • Vitamin C-: Scurvy. • Iodine-: Goitre or Cretinism. 5. a) How does carbon dioxide released from the tissue of an insect get to the atmosphere? Carbon dioxide produced by the insect's tissues during metabolism diffuses directly into the tracheoles, which are the finest branches of the tracheal system. From the tracheoles, it moves into larger tracheae and then exits the insect's body through openings called spiracles into the atmosphere. This process relies on diffusion gradients and does not involve the circulatory system. b) How are aerenchyma tissue adapted to their function? Aerenchyma tissue is adapted to its function by: • Having large air spaces (lacunae) that facilitate the efficient transport of gases, particularly oxygen, to submerged parts of the plant for respiration. • Providing buoyancy to aquatic plants, allowing them to float and keep their photosynthetic parts above water.
