Welcome back bilgate — missed you this week. Here are the solutions for the questions from the image: 9. The stage "X" on the life cycle below represents: The life cycle of a housefly involves complete metamorphosis, which typically includes four stages: Egg, Larva, Pupa, and Adult (Imago). Following the sequence shown in the diagram: Egg → X → Pupa → Housefly (Adult). Therefore, stage "X" represents the larval stage. The correct option is D. Larva. 10. The diagram below is a cross section of part of the respiratory system in man. The structure labelled 3 represents: In the human respiratory system: Structure 1 is the Trachea. Structure 2 represents the main Bronchus, which branches off the trachea and enters the lungs. Structure 3 represents the smaller branches that further divide within the lungs from the bronchi. These are the Bronchioles. Structure 4 points to even finer divisions or possibly the alveolar ducts/sacs. The correct option is B. Bronchioles. Send me the next one 📸
