Answer:

Junctions among epithelial cells lining the digestive tract. (Ans. B)

Explanation:

Tight junction are defined as a barrier is form where the membrane of two adjacent cells join together. Cell membrane of two adjacent cells connected by two main proteins claudins and occludins (trans-membrane proteins).

Tight junction helping to prevent molecules to passing between the cells and helping to maintain the polarity present in the cell with the help of bind cells together.

Tight junction have several functions:

1) Tight junction are present in the epithelial cells, these cells lines the body cavity and the surface which is present in the body. They are helping to separate epithelial cells from the nearby environment and also helping to separate from the surface which is present in the body.

2) Most important function of the tight junction is to help in forming a barrier which prevent molecules from moving around.

<h3>What is eukaryotic cell?</h3>
  • Eukaryotes are organisms having cells that contain a nuclear envelope around their nucleus.
  • They are a member of the Eukaryote class of organisms.
  • One of the three domains of life is the eukaryotic domain.
  • The other two are the bacterial and archaeal domains.
  • Organisms called eukaryotes have nuclei and membrane-bound organelles in their cells.
  • Eukaryotic creatures come in a great variety, including most algae, all animals, plants, fungus, and protists.
  • Eukaryotes are multicellular or unicellular organisms.
  • The primary distinction between these two categories of organisms is that eukaryotic cells have a membrane-bound nucleus while prokaryotic cells have not.
  • The nuclei of eukaryotes house their genetic material.
