B - Tubular parts of nephrons

C - Inner lining of ducts of salivary glands

D - Walls of blood vessels

1. A and B
2. B, C and D
3. A, B and C
4. A and C

Q. Identify the incorrect statement about epithelial tissues.

1. The free surface faces the body fluid or the outside environment
2. The cells are compactly packed with little intercellular spaces
3. Compound epithelium play a major role in secretion and absorption
4. They have specialised cell junctions

Q. Assertion: The squamous epithelium is made of a single thin layer of flattened cells with irregular boundaries.

Reason: They are found in walls of blood vessels and air sacs of wings.

1. If both assertion and reason are true and reason is the correct explanation of assertion
2. If both assertion and reason are true but reason is not the correct explanation of assertion
3. If both assertion and reason are false
4. If assertion is true but reason is false
