Explanation:

• For Question 19: The basement membrane is formed by the union of the basal and fibroreticular laminae. It serves as a support structure between epithelial and connective - tissue.
• For Question 20: Goblet cells produce mucus, which is a lubricating substance that helps protect and moisten epithelial surfaces.
• For Question 21: Intercalated disks are unique to cardiac muscle. They contain gap junctions and desmosomes that allow for synchronized contraction of cardiac muscle cells.
