Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of cell junction would most likely be found in the intestinal tract?
A
Gap
B
Tight
C
Adhering
D
Plasmodesmata
Explanation: 

Detailed explanation-1: -Adherens junctions. (A) Adherens junctions, in the form of adhesion belts, between epithelial cells in the small intestine.

Detailed explanation-2: -Tight junctions (TJs) play an important role in intestinal barrier function. TJs in intestinal epithelial cells are composed of different junctional molecules, such as claudin and occludin, and regulate the paracellular permeability of water, ions, and macromolecules in adjacent cells.

Detailed explanation-3: -Occluding junctions The borders of two cells are fused together, often around the whole perimeter of each cell, forming a continuous belt like junction known as a tight junction or zonula occludens (zonula = latin for belt).
