Answer 1

Best choice: computer-generated model.

Why: Formation of blood cells (hematopoiesis) is a dynamic, microscopic cellular process that occurs inside bone marrow. A computer-generated model can show the stages of stem‑cell differentiation, cell morphology changes, timing, and signaling events that you cannot see in a static or macroscopic specimen.

Brief comparison of the listed models:
- Dissected pig: realistic anatomy and can show bone and marrow tissue, but is macroscopic and static; it won’t clearly show the cellular steps of blood‑cell formation without further microscopic preparation.
- Plastic bone: good for gross anatomy (shape, cavities) and safe/reusable, but purely structural and cannot demonstrate cellular processes.
- Computer-generated model: can illustrate microscopic, time‑dependent processes, cell types, and interactions—best for showing how blood cells form.
- Photograph of a bone: static, two‑dimensional, and usually external only; does not show marrow activity or the formation process.

Note: For observing actual cells forming, the best real-world specimen would be a bone‑marrow smear and microscope images/time‑lapse microscopy, which aren’t listed.
