Tick mark the statement which is not correct with respect to cockroach?
1. In cockroach the grinding of the food particles is performed by mandibles & gizzard.
2. Malpighian tubules help in the removal of nitrogenous wastes in the form of urea & ammonia.
3. Midgut gut of cockroach absorb food.
4. Main body cavity is called haemocoel.
What is true regarding the morphology of Periplaneta americana?
1. Head is formed by the fusion of 10 segments
2. Hypopharynx acts as the tongue
3. The first pair of wings arise from the prothorax
4. Anal cerci are not seen in females
Select the correct route for the passage of sperms in male frogs:
| 1. | Testes → Vasa efferentia → Kidney → Seminal Vesicle → Urinogenital duct → Cloaca |
| 2. | Testes → Vasa efferentia → Bidder's canal → Ureter → Cloaca |
| 3. | Testes → Vasa efferentia → Kidney → Bidder's canal → Urinogenital duct → Cloaca |
| 4. | Testes → Bidder's canal→ Kidney→ Vasa efferentia → Urinogenital duct→ Cloaca |
| 1. | Presence of a boat shaped sternum on the 9th abdominal segment |
| 2. | Presence of caudal styles |
| 3. | Forewings with darker tegmina |
| 4. | Presence of anal cerci |
Reason (R) These canals are the part of frog’s reproduction system and connect to the cloaca of frog.
1. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
2. Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion
3. Assertion is true, but Reason is false
4. Both Assertion and Reason are false
Which type of tissue is correctly matched with its location?
| Tissue | Location | |
| 1. | Areolar tissue | Tendons |
| 2. | Transitional epithelium | Tip of nose |
| 3. | Cuboidal epithelium | Lining of stomach |
| 4. | Smooth muscle | Wall of intestine |
The function of the gap junction is to?
| 1. | Perform cementing to keep neighbouring cells together |
| 2. | Facilitate communication between adjoining cells by connecting the cytoplasm for rapid transfer of ions, small molecules and some large molecules |
| 3. | Separate two cells from each other |
| 4. | Stop substances from leaking across a tissue |
The terga,sterna and pleura of the cockroach body are joined by:
1. cementing glue
2. muscular tissue
3. arthrodial membrane
4. cartilage
