Tight junctions are cell junctions that seal tissues. These junctions form protective and functional barriers.
- The cell junction that is involved in creating a barrier between cells is the TIGHT junction.
- The tight junctions are cell-cell adhesion structures implicated in cell polarity and signaling.
- On the other hand, adherens junctions are cell junctions required for maintaining contact inhibition.
- Finally, desmosomes are intercellular junctions that bind intermediate filaments of the cytoskeleton with cadherin proteins.

When red blood cells are in a higher concentrated solution, water flows out of the cells faster than it comes in. This results in crenation or shrivelling of the cell.
Answer:
Gravity
Explanation:
When its altitude is matched by the pull of the Earth's gravity, a satellite circles Earth. The satellite will fly off into orbit in a straight line or crash down to Earth without this equilibrium.
By juggling two things, a satellite retains its orbit: its velocity (the speed it takes to travel along a straight line) and the gravitational force on it that the Planet provides. To resist the greater gravitational force, a spacecraft orbiting closer to the Earth needs more velocity.
