Final answer:
The structure at the same level of organization as the image labeled 4 in the diagram is C. Muscle tissue, which is at the tissue level.
Step-by-step explanation:
The levels of organization in the human body include cells, tissues, organs, and organ systems. When considering the diagram labeled 4, which is referring to a level of organization in the body, we need to identify a structure that is at the same level of organization. Among the options provided:
A nerve cell is at the cellular level,A digestive system is an organ system,Muscle tissue is at the tissue level, andLungs are an organ.
Since tissues are a collection of similar cells that perform a specific function, and considering that the image labeled 4 refers to a tissue level, the correct answer would be C. Muscle tissue, as it is at the same level of organization as the tissue illustrated in the diagram.
