Final answer:
The extracellular matrix (ECM) is responsible for connecting cells to the external environment and ensuring correct positioning of the cells to prevent metastasis. Collagens, the major protein component of the ECM, provide strength, flexibility, and support to various tissues.
Step-by-step explanation:
The extracellular matrix (ECM) is responsible for connecting cells to the external environment and ensuring correct positioning of the cells to prevent metastasis. It is composed of various components, including collagens, which are the major protein component of the ECM. Collagens are present in tissues such as skin, bone, tendon, and cartilage. They provide strength, flexibility, and support to these tissues.
