The statement about extracellular matrix (ECM) that is accurate is: "It varies in consistency based on the amount of protein fibers and fluid." The ECM can indeed have varying physical properties depending on its composition, including the types and amounts of protein fibers such as collagen and elastin, as well as the volume of interstitial fluid. These components contribute to the ECM's consistency, which can range from the solid form in bone to the gel-like form in cartilage to the more fluid form in blood.
