Tight junctions help to stop substances from leaking across a tissue.
Adhering junctions perform cementing to keep neighbouring cells together.
Gap junctions facilitate the cells to communicate with each other by connecting the cytoplasm of adjoining cells, for rapid transfer of ions, small molecules and sometimes big molecules.
All of the above
There are 16 very long malpighian tubules present at the junctions of midgut and hindgut.
Grinding of food is carried out only by the mouth parts.
Nervous system is located ventrally and consists of segmentally arranged ganglia joined by a pair of longitudinal connectives.
Females bear a pair of short thread like anal styles.

Glandular epithelium
It is an epithelial tissue.
It is composed of a single layer of cube-like cells.
They are found in the walls of blood vessels and air sacs of lungs.
Secretion and absorption are the main functions of these tissue.
It is made of more than one layer of cells and thus has a limited role in secretion and absorption.
Their main function is to provide protection against chemical and mechanical stresses.
They cover the dry surface of the skin, moist surface of buccal cavity, pharynx, inner lining of ducts of salivary glands and pancreatic ducts.
