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 |
In male cockroaches, sperms are stored in which part of the reproductive system?

2. Mushroom glands
3. Testes
4. Vas deferens
Smooth muscles are:

2. voluntary, multinucleate, cylindrical
3. involuntary, cylindrical, striated
4. voluntary, spindle-shaped, uninucleate
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 |
1. | Indeterminate and radial cleavage during embryonic development |
2. | Exoskeleton composed of N-acetylglucosamine |
3. | Metamerically segmented body |
4. | -Schizocoelom as body cavity |
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
Choose the correctly matched pair:
1. Tendon-Specialized connective tissue
2. Adipose tissue-Dense connective tissue
3. Areolar tissue- Loose connective tissue
4. Cartilage- Loose connective tissue
Choose the correctly matched pair:
