1. The answer is D. Donate bone marrow allows those in need to produce blood and fat. To determine the answer, one can understand the purpose of bone marrow. Bone marrow is responsible for producing blood cells, including red blood cells, white blood cells, and platelets. Additionally, it also produces some types of fat cells. Therefore, donating bone marrow helps those in need to produce blood and fat.
2. The answer is C. The 2D image is less accurate in showing how the organs look, such as their texture. To determine the answer, one can consider the limitations of a 2D computer-generated image. A 2D image can only depict organs in two dimensions, which means it lacks depth perception. It does not accurately represent the three-dimensional structure and texture of the organs. Therefore, using a 2D image of the digestive system is limited in providing an accurate depiction of the organs' appearance.
3. The answer is A. Models focus on specific details. To determine the answer, one can consider the characteristics of models. A model is a simplified representation of a system or object. Models are created to emphasize specific details or aspects of the system being studied. They are not always intended to perfectly mimic the system, nor are they considered fixed and unchanging. Models can be updated as new information or knowledge is gained. Therefore, the statement that correctly describes a model is that it focuses on specific details.
4. The answer is C. A computer-generated model best illustrates the formation of blood cells. To determine the answer, one can compare the different types of models listed. A plastic bone, photograph of a bone, and a dissected pig do not specifically focus on the formation of blood cells. However, a computer-generated model can be designed to depict the process of blood cell formation accurately. Therefore, a computer-generated model is the best choice for illustrating the formation of blood cells.
5. The answer is C. A 3D computer-generated model. To determine the answer, one can consider the requirements for a complete model of the skeleton. A complete model of the skeleton should provide a comprehensive representation of the skeletal system, including the different bones and their spatial relationships. A dissected human would be impractical and unethical for all practical applications. A 2D computer-generated model lacks depth perception and may not accurately reflect the three-dimensional structure of the skeleton. However, a 3D computer-generated model can provide an interactive and detailed representation of the skeleton, making it the most useful option for practical applications. Therefore, a 3D computer-generated model would be the best choice.
