Which one of the following is the correct statement about the circulatory system of cockroach?
1 It is closed type of circulatory system
2 It is a complicated type of circulatory system
3 It takes place without the participation of tissue
4 It has 13-chambered heart and in each segment one pair of ostia are present
Explanation:
D The heart of the cockroach is elongatedthickmusculartubular and 13-chambered. - Cockroaches have an open circulatory system. They took blood vessels and capillaries. Dorsal sclerite is called tergum or tergiteventral is called sternum or sternite and two lateral are called pleura or pleurisies.

Abdominal ganglia in cockroach are found in segments:
1 12346 and 7
2 \(1,2,3,4,5\) and 6
3 \(3,4,5,6,7\) and 8
4 89and 10
Explanation:
A Cockroach has in total 9 ganglia in number. Out of these ganglia3 are present in the thorax and 6 are present in the abdomen. - These six ganglia are present in the \(1^{\text {st }}2^{\text {nd }}3^{\text {rd }}4^{\text {th }}6^{\text {th }}\) and \(7^{\text {th }}\) segment of the nervous system of the cockroach. - Each ganglion of the nerve cord is formed by the fusion of two ganglia except the ganglion in the \(7^{\text {th }}\) abdominal segment is the largest of the all the abdominal ganglia and probably formed by the fusion of 3 pairs of ganglia.

Moulting hormone is secreted by :
1 corpora cardlacum
2 prothoracic gland
3 corpora allata
4 neurosecretory hormone
Explanation:
B Moulting hormones (ecdysones) are a group of steroid hormonesfound in insects and crustaceanwhich are responsible for maintenance of the normal moultinggrowth and maturation pattern. It is a steroid hormone secreted by prothoracic gland that in its active formstimulates metamorphosis and regulates melting in insects.

Hepatic caecae in cockroach are derived from :
1 crop
2 ileum
3 midgut
4 gizzard
Explanation:
C The hepatic caecae is present at the junction of the foregut and midgut of the cockroach. The midgut is the middle part of the digestive system of cockroaches. It is responsible for the digestion and absorption of food. Their function is to secrete the digestive juices to facilitate digestion.
