Which level of organization is higher: ___ or ___?

The correct response highlights the hierarchy of biological organization in living organisms. In this hierarchy, organs represent a more complex level of organization than simple tissues. Organs are composed of multiple types of tissues working together to perform specific functions essential for the organism's survival.

When comparing cells to molecules, cells are indeed a higher level of organization. Cells are the fundamental units of life that can carry out all life processes, while molecules are made up of atoms and represent a simpler organizational structure. Cells consist of various molecules, such as proteins, lipids, and nucleic acids, which contribute to their structure and function. Thus, understanding this differentiation is crucial, as it illustrates how biological systems are structured from the simplest (molecules) to the more complex (cells, then tissues, then organs, and so on).
