B)gap junction
C)tight junction
D)ion channel

Question

Quizplus · Accepted Answer

Desmosomes are the intercellular junctions that provide strong adhesion between adjacent epithelial cells, making them best suited for providing toughness and resistance to shearing and stretching in the epidermis. Gap junctions allow for communication between cells, tight junctions create a barrier to prevent leakage between cells, and ion channels are membrane proteins that allow the transport of ions across cellular membranes.
