Question

question 19 (2.5 points)
why are adhering junctions common in tissues subject to constant abrasion or stretching, such as skin?
these cells need to communicate by allowing cytoplasm to flow between adjacent cells
the cells in these tissues require strong cell - to - cell junctions to hold them together
adhering junctions prevent harsh enzymes from flowing between adjacent cells
these tissues do not have basement membranes
adhering junctions allow production of a protective cuticle

Explanation:

Adhering junctions are cell - to - cell junctions. In tissues like skin that are subject to abrasion or stretching, cells need to be held together strongly. Communication via cytoplasm flow (gap junctions) is not the function of adhering junctions. Adhering junctions are not related to preventing enzyme flow (tight junctions are more about preventing paracellular flow in some cases). Tissues like skin do have basement membranes. And adhering junctions do not directly allow for the production of a protective cuticle.

Answer:

The cells in these tissues require strong cell - to - cell junctions to hold them together.
