Give an example of an abnormality or problem at one level of organization, and explain how it affects other levels of organization
What will be an ideal response?
The levels of organization are dependent upon one another. Beginning with the chemical level, if the incorrect atom is put into a protein, then the protein does not function properly. Because this protein is ultimately part of a cell, or the cell's extracellular matrix, the tissue will not work correctly. It is possible that the type of tissue containing this protein is found in an organ, and possibly in many organs, therefore affecting multiple organ systems. Cystic fibrosis is a great example of a faulting protein that affects multiple organ systems.
