What are the steps involved in the 'Ход работы' (Work Plan)?

The work plan involves several steps: 1. Examining the external structure of a mammal and identifying the main body parts (head, tail). 2. Observing a mammal's skeleton, noting its sections and how bones are connected. 3. Studying the skull's structure, form, and bone articulation. 4. Examining teeth, counting them, and distinguishing between incisors, canines, and molars. 5. Identifying the vertebral column and its sections, analyzing the features of each section and their correlation. 6. Studying the rib cage, its function in protecting the lungs and aiding respiration. 7. Observing the skeleton of the limbs and identifying the limb girdles, specifying their bone composition. 8. Identifying similarities and differences between the skeletons of mammals and reptiles. 9. Drawing conclusions and recording them in a notebook.
