Question

the diagram shows the model of the hierarchical organization of the muscular system. / el diagrama muestra el modelo de la organización jerárquica del sistema muscular. which of these best explains the next level of organization? / ¿cuál de estas opciones explica mejor el siguiente nivel de organización? mitochondria, because they are smaller than cells and have membranes / mitocondrias, porque son más pequeñas que las células y tienen membranas. mitochondria, because they produce energy for movement / mitocondrias, porque producen energía para el movimiento. muscle cells, because they are the smallest living unit in the body / células musculares, porque son la unidad viva más pequeña del cuerpo. muscle cells, because they contain protein / células musculares, porque contienen proteínas

Explanation:

The hierarchical organization of the muscular system starts from the whole - body level, then to muscle organs, and the next level down is the muscle cells. Cells are the basic living units of tissues and organs. Mitochondria are organelles within cells, not the next level of organization after the whole - muscle structure shown. Muscle cells are the appropriate next level as they make up the muscle tissue.

Answer:

Muscle cells, because they are the smallest living unit in the body / Células musculares, porque son la unidad viva más pequeña del cuerpo.
