Final answer:
Collagen is the molecule that allows the extracellular matrix of animal tissues to resist compression. Hence, A) is correct.
Step-by-step explanation:
The molecule that allows the extracellular matrix of animal tissues to resist compression is collagen. Collagen is the most abundant protein in the extracellular matrix and forms fibrils that provide strength and structural stability to tissues. It helps tissues withstand external stresses and gives them their distinct properties.
For example, collagen is found in various tissues such as skin, bone, tendon, and cartilage. It is responsible for maintaining the shape and providing structural support to these tissues.
