1. The answer is C. Bones.
Explanation: People donate bone marrow so that those in need can produce bones. To get the answer, one must have knowledge about bone marrow and its function in the body. Bone marrow is a soft, spongy tissue found inside the bones. It is responsible for producing new blood cells, including red blood cells, white blood cells, and platelets. This process is called hematopoiesis, and it occurs in the bone marrow. By donating bone marrow, individuals can help others who have diseases affecting their bone marrow and need healthy stem cells to regenerate their blood cells.
2. The answer is B. The 2D image does not show all of the organs since some of them overlap.
Explanation: A limitation of using a 2D computer-generated image of the digestive system is that it may not show all the organs accurately because some of them may overlap. A 2D image lacks depth perception and can only represent the body in two dimensions, such as on a screen or a piece of paper. In contrast, the actual thing, such as a physical model or the human body itself, allows for a three-dimensional representation, which provides more accurate spatial relationships and a better understanding of the positioning of organs.
3. The answer is B. Models focus on specific details.
Explanation: A model is a simplified representation of a system or concept that highlights specific details of interest. Models aim to capture the essential features or behaviors of the original system while representing them in a more manageable and understandable form. Models can be physical or conceptual, and they are often used in science, engineering, and other fields to study, analyze, and predict the behavior of complex systems. However, models are never perfect replicas of the actual system and may have limitations or simplifications.
4. The answer is C. Computer-generated model.
Explanation: Among the given options, a computer-generated model would best illustrate the formation of blood cells. This is because computer-generated models can simulate complex processes and provide visual representations that show the formation of blood cells accurately. Computers can simulate interactions between cells, tissues, and molecules, allowing researchers and scientists to study and understand processes that are difficult to observe directly. In this case, a computer-generated model can provide insights into the formation of blood cells, highlighting the different steps involved in hematopoiesis.
5. The answer is A. A 3D computer-generated model.
Explanation: A complete model of the skeleton that would be useful for all practical applications would be a 3D computer-generated model. A 3D computer-generated model can provide a detailed and accurate representation of the skeleton, allowing for dynamic visualizations, interactive exploration, and even virtual dissection. It can be used in various practical applications, such as medical education, surgical planning, biomechanical analysis, and even animation or gaming. A 2D computer-generated model would lack depth and spatial understanding, limiting its usefulness in practical applications.
