In vertebrates, there are three major types of cell junction:1. Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions.)2. Gap junctions (communicating junction)3. Tight junctions (occluding junctions)Your question most likely is for the tight junction but more information in the question would be helpful.

Tight junction - impermeable junction that encircles the cell Desmosome - anchoring junction scattered along the sides of cells Gap junction - a nexus that allows chemical substances to pass between cells
Membrane junctions are specialized structures that are formed between adjacent cells, providing mechanical strength and facilitating cell-cell communication. These junctions include adherens junctions, tight junctions, desmosomes, and gap junctions, each with unique functions in cell adhesion, barrier formation, and signal transfer.
If the layer of impermeable rock is below the water table, then the water table is likely above the impermeable rock and the groundwater will be trapped above it. If the impermeable rock is above the water table, then the water table is likely below the impermeable rock layer and the groundwater will not be able to pass through it.
a. anchoring junctions
Cell junctions in plants are called Plasmodesmata while communicating junctions in animal cells are gap junctions
Tight junctions between animal cells create an impermeable barrier that prevents the passage of molecules between cells. These junctions seal the space between cells, controlling the movement of substances. Tight junctions are important in maintaining tissue integrity and barrier function in organs such as the intestines and blood-brain barrier.

Gap junctions aid in the coordination of activities of adjacent animal cells by allowing direct communication and exchange of ions, molecules, and electrical signals between the cells. This enables synchronized responses and coordinated functions, such as in cardiac muscle tissue for rhythmic contractions.

Junctions on roads are intersections.

There are 31 Junctions on the M25
Impermeable means that stuff can't go through it. Wax is impermeable to water. Paper towels are not. Glass is impermeable to air. Mesh cloth is not. Some things are impermeable to one thing but not another. Clear plastic is impermeable to water and air, but not light. Lead metal is impermeable to x-rays, but not heat. Which layer is impermeable depends on what it is impermeable to.
Yes, plastic wrap is impermeable.
