As Earth orbits the Sun, this same principle is used by astronomers to determine the distance to nearby stars. ... Parallax is the first "inch" on the yardstick with which astronomers measure distances even further to objects.
 
        
             
        
        
        
Answer:
The correct answer is - tight junctions.
Explanation:
Tight junctions are one of the cell-cell junctions that make a barrier to the passage of material which is a present in epithelia. This barrier is impermeable to most of the materials with soluble molecules. This barrier is made up of the occludin and claudin proteins.
Tight epithelia have tight junctions and examples of such junctions are the distal convoluted tubule or DCT, and the collecting duct of the nephron in the kidney.
Thus, the correct answer is - tight junctions.
