Answer 1

Various structures in the human body are organized into levels, from cells to whole organisms. Each item listed is categorized as either a cell (C), tissue (T), organ (O), organ system (S), or whole organism (W) based on its role in the body's structure.

1. Lung - O (Organ)
2. Bone - O (Organ)
3. Tongue - O (Organ)
4. Brain, spinal cord, nerves - S (Organ System)
5. Red blood cell - C (Cell)
6. Honey bee - W (Whole Organism)
7. Large intestine - O (Organ)
8. Brain stem cell - C (Cell)
9. Tongue, stomach, small intestine - S (Organ System)
10. Muscle - T (Tissue)
11. Tomato plant - W (Whole Organism)
12. Cheek lining - T (Tissue)

In summary, cells are the basic units of life, tissues are groups of similar cells that perform a common function, organs are composed of different types of tissues, and organ systems are composed of different organs that work together to perform complex functions. A whole organism comprises several organ systems working in harmony.
