Final answer:

An adherens junction is the cell junction that resembles a belt near the apical surface of a cell and connects it to neighboring cells, facilitating signal transmission via cadherin clusters. so, option 4 is the correct answer.

Step-by-step explanation:

The cell junction that encircles a cell like a belt near its apical surface and binds a cell to its surrounding neighbors is known as an adherens junction. These junctions are characterized by the presence of cadherin clusters that allow for signals to be transmitted from the exterior to the cytoplasm. They can use either cadherins or integrins depending on whether they are linking to other cells or to the matrix, and are associated with the contractile protein actin located on the inner surface of the cell membrane.

Adherens junctions encircle a cell like a belt near its apical surface and bind a cell to its surrounding neighbors. They provide a pathway for signals to be transmitted from the cell exterior to the cytoplasm.

The cell junction that encircles a cell like a belt near its apical surface and binds a cell to its surrounding neighbors is called adherens junctions. The cadherin clusters of adherens junctions provide a pathway for signals to be transmitted from the cell exterior to the cytoplasm. Adherens junctions use cadherins and are characterized by the presence of the contractile protein actin. They influence the shape and folding of the epithelial tissue.
