2. Sclerites	b. Articular membrane
3. Tergites	c. Protein of exoskeleton
4. Sternites	d. Sclerites on dorsal side
5. Arthrodial membrane	e. Sclerites on ventral side

• A. 1.⇒ c, 2.⇒ d, 3.⇒ e, 4.⇒ b, 5.⇒ a.
• B. 1.⇒ d, 2.⇒ e, 3.⇒ a, 4.⇒ b, 5.⇒ c.

Answer 1

The correct option is C

1.⇒ c, 2.⇒ a, 3.⇒ d, 4.⇒ e, 5.⇒ b.

1. Chitin is the protein that makes up the exoskeleton of many arthropods.

2. Sclerites are the hard exoskeleton plates in cockroach.

3. Tergites are the sclerites found on the dorsal side.

4. Sternites are the sclerites on the ventral side.

5. Arthrodial membrane refers to the articular membrane.
