Which pair shows a relationship analogous to deltoid and radius?

• A. Tissue : Organ
• B. Brain : Nerve
• C. Blood : Vein
• D. Scalpel : Incision

Answer: (A)

To understand why the pair "Tissue : Organ" represents a relationship analogous to "deltoid : radius," it's essential to analyze the nature of the relationship in each pair. The deltoid muscle is a specific type of muscle that contributes to the overall function of the shoulder and upper arm, but it is just one part of a larger system—the arm. Similarly, a tissue is a group of cells that work together to perform a similar function and, when combined with other tissues, forms an organ. Therefore, both relationships illustrate a component (deltoid muscle, tissue) contributing to a more complex structure (arm, organ). In contrast, the other options do not represent the same hierarchical or anatomical relationship. While they might possess some connection within biological contexts, they do not capture the same part-to-whole relationship. For instance, the relationship between "brain" and "nerve" represents different functional components of the nervous system rather than a hierarchical anatomical structure. "Blood" and "vein" describe a fluid within a vessel rather than highlighting a membership in a broader anatomical category. Lastly, "scalpel" and "incision" relate to a tool and the action it performs, which does not align with the structural
