The similarity between star fish, planaria, tape worm, hydra, sponges and spiders is

  1. They all exhibit both sexual and asexual reproduction.

  2. They all reproduce by budding.

  3. They all have power to regenerate.

  4. They all live in colonies.


Correct Option: C
Explanation:

All the animals, i.e. star fish, tapeworm, hydra, spider, sponges and planaria have power to regenerate.

In which phenomenon do the gamete nuclei of the same cell unite together to form a new individual?

  1. Parthenogenesis

  2. Automixis

  3. Plasmotomy

  4. Regeneration


Correct Option: B
Explanation:

Automixis is the phenomenon in which the gamete nuclei of the same cell unite together to form a new individual.

Synkaryon formation takes place during conjugation.

Which is the exclusive mode of reproduction adapted by lizard lacerta saxicola americana?

  1. Incomplete parthenogenesis

  2. Complete parthenogenesis

  3. Syngamy

  4. Regeneration


Correct Option: B
Explanation:

Lizard lacerta saxicola americana reproduce exclusively by complete parthenogenesis and only females are found in nature.
