Final answer:
The structural organization in humans is hierarchical. It starts with cells forming tissues, tissues forming organs, and organs forming organ systems. The correct answer to the student's question is a) Two or more types of muscle tissues working together make an organ.
Step-by-step explanation:
The structural organization in humans, as shown: heart, cardiac muscle cell, cardiac heart vein, muscle, artery tissue, circulatory system is created through a hierarchical method. The answer to the statement that explains how each level of the organization is created is option a) Two or more types of muscle tissues working together make an organ. This is because a single cell, such as a cardiac muscle cell, cannot perform the functions of the heart by itself. When a group of similar muscle cells work together, they form muscle tissue. This muscle tissue, when combined with other types of tissues (cellular structures with the same functionality), make up an organ such as the heart. Tissues and organs then combine to form organ systems, like the circulatory system.
