  1. Ova

  2. Sperms

  3. Both A and B

  4. None of the above

Show answer
Correct Option: B
Explanation:

Bidder's canal is present in male frogs. Vasa-efferentia opens into the Bidder's canal and the Bidder's canal is connected to longitudinal collecting tubules by means of a number of transverse collecting ducts and helps in the passing of the sperms. So, the correct answer is option B.

Vasa efferentia in frog carry sperms to

  1. Male cloaca

  2. Female cloaca

  3. Mullerian duct

  4. Bidder's canal

Show answer
Correct Option: D
Explanation:

In all terrestrial vertebrates except the placental mammals, the genital ducts and excretory ducts, open into the cloaca. In mammals, however, the cloaca becomes separate into a dorsal part, which conveys the faeces and a ventral part, which receives excretory and genital products. The sperm cells from seminiferous tubules pass into Bidder's canal through vasa efferentia. The Bidder's canal runs along the length of each kidney near its inner side. Thus, vasa efferentia conduct mature sperm from testis to the ureter.

Therefore, the correct answer is option D.

  1. Yolk sac

  2. Zooplanktons

  3. Protozoa

  4. Aquatic vegetations

Show answer
Correct Option: B
Explanation:

Tadpole larva has a rudimentary mouth which is not highly developed. Thus frog tadpole is a herbivore, feeding on relatively simpler food found available in the aquatic systems, such as Zooplanktons. Upon growth, tadpole larva undergoes metamorphosis where the mouth and internal organs will be rearranged to develop an adult carnivorous lifestyle.


Thus, the correct option is "(B) Zooplanktons".
