The correct answer is E. Focal adhesions.Focal adhesions are specialized structures that allow cells to adhere to the extracellular matrix and to each other. They are not a function of epithelial tissue, but rather a feature of other types of tissues, such as connective tissue.The other options are all functions of epithelial tissue:A. Zonula occludens (tight junctions) are specialized structures that prevent the passage of molecules and ions through the space between cells, forming a barrier that separates the apical and basolateral surfaces of epithelial cells.B. Macula adherens (adherens junctions) are specialized structures that link the actin cytoskeleton of one cell to that of an adjacent cell, providing mechanical stability to the tissue.C. Gap junctions are specialized structures that allow the passage of ions and small molecules between cells, allowing for communication and coordination of cellular activities.D. Zonula adherens (adherens junctions) are specialized structures that link the actin cytoskeleton of one cell to that of an adjacent cell, providing mechanical stability to the tissue.Therefore, the correct answer is E. Focal adhesions.
