A The heart of cockroach is neurogenic because it requires a nervous impulse to contract. On the wall of the heartcluster of neurons is present that produces the rhythmic output for the heartbeat. - In the neurogenic heartpresent in most arthropods like cockroachesthe heartbeats are initiated by a nerve signal. Hencethe cockroach has a neurogenic heart.

Externally male and female cockroach can be differentiated by:
1 Wingless condition
2 Length of abdomen
3 Length of maxillae
4 Conglobate gland
Explanation:
B The body of male cockroach is smaller than the female cockroach's body. The body of female cockroach is relatively larger than the male body. The abdomen of the female is boot shaped and the last segments blunt. Hencethe male and female cockroach can be differentiated by length of abdomen.

Which among these is not involved in excretion in cockroaches?
1 Malphigian tubules
2 Nephrocytes
3 Urecose glands
4 Maxillary palps
5 Fat body
Explanation:
D Exertion in cockroach is primarily performed by malpighian tubules. They absorb nitrogenous waste products and convert them into uric acid. Malphigian tubules situated at the junction of Malphigian tubules at the Hindgut and midgut. In additionthe fat bodynephrocytes and urecose glands also help in excretion. While the maxillary pulps are used for cleaning the antennae and also the front pairs of legs.
