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.
The correct answer that would best complete the given statement above would be A TWO-HEADED FLY. A high concentration of bicoid protein at the opposite ends of a developing drosophila embryo would result in the development of a two-headed fly. The bicoid <span>gene is a type of egg-polarity gene and is transcribed by nurse cells. </span>
