Final answer:
The term 'atrophy' means no development and refers to the wasting away of a body part or tissue.
Step-by-step explanation:
The term that means no development is atrophy. Atrophy refers to the wasting away or reduction in size of a body part, commonly due to the degeneration of cells, or from disuse. Other terms listed, such as anemia, antibody, and antigen, represent different concepts within biology. Anemia is a condition marked by a deficiency of red blood cells or of hemoglobin in the blood, leading to fatigue among other symptoms. An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. An antigen is any substance that causes your immune system to produce antibodies against it.
This question would fall within the context of studying immune system disorders, where understanding the development or the lack thereof, of components like antibodies, is key.
