3 10,11
4 8,10
5 9,9
Explanation:
A The body of the cockroach is segment and divisible The back part of the body is called abdomen. The abdomen of an adult cockroach has 10 segments (male and female) while an embryo has 11 segments.

Blatta orientalis can be distinguished from periplaneta americana in that the female of Blatta is with
1 smaller wings
2 vestigeal wings
3 large wings
4 large eyes
Explanation:
B It differs from blatta in having a wider body and wings in both sexes and they can fly. Both Periplaneta Americana and Blatta orientalis are feathers of the genus. In these sectionsfeathers are either developed or inconspicuous. Hencethey differ in the absence of the development of a single pair.

What is not a common feature is Periplaneta and Scorpions?
1 Excretory organs are malpighian tubules
2 No appendages in abdomen
3 Respiratory organs are trachea
4 Both are mostly terrestrial arthropods
Explanation:
C Periplaneta or cockroaches and scorpions are of the kingdom animal and phylum arthropoda. They have many similar characteristics. The excretory organs in both are the malpighian tubules. - Spiracles are the small openings present along the edges of the abdomen of periplanetathrough which respiratory gases are carried and from tissues via small tubes called tracheae. Series of vascular thin plates called a book lungs to serve as a respiratory organ in Scorpion.
