What is one limitation of a using a 2D computer-generated image of the digestive system instead of using the actual thing? (1 point)

The 2D image is less accurate in showing how the organs look, such as their texture.

The 2D image is too small and the organs are, therefore, difficult to see.

The 2D image does not show all of the organs since some of them overlap.

The correct answer is D. blood and fat.
Bone marrow is a spongy tissue that is found in the center of various bones in the body, including the hip, thigh, and breastbone. It is responsible for the production of various blood components, including red blood cells, white blood cells, and platelets. These blood components are vital for the proper functioning of the circulatory and immune systems.
When someone donates bone marrow, they are providing a source of healthy blood-forming cells to individuals who have certain diseases or conditions that affect their own bone marrow. The donated marrow contains hematopoietic stem cells, which can develop into different types of blood cells.
In addition to blood cells, bone marrow also contains adipose (fat) cells. However, the primary purpose of bone marrow donation is to help individuals with blood-related disorders, rather than to produce fat or muscles. Therefore, option D, blood and fat, is the correct answer.
