A Correct answer
Explanation

Beroe (comb jellyfish) belong to the Ctenophora. Monocystis is an endoparasite found in the seminal vesicles and coelom of earthworm (Annelida). Wuchereria is a human parasitic roundworm (Aschelminthes) known to cause lymphatic filariasis. Pennatula is colonial marine cnidarian. Cleiona belongs to Porifera.

Therefore, the correct answer is option A.

C Correct answer
Explanation

Ctenophores are commonly known as sea whales or comb jellies, radially symmetry, diploblastic organisms with tissue level of organization. The body bears eight external rows of ciliated comb plates which help in locomotion, hence the name Ctenophora. Cnidocytes are absent.

So the correct answer is 'Ctenophora'.

Select the wrongly paired one from the following.

  1. Flats worms - Tape worm and liver fluke

  2. Sea walnuts - Hydra and Obelia

  3. Homoiothermous - Aves and mammals

  4. Incomplete digestive system - Platyhelminthes
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

a) Tape worm and liver fluke belongs to phylum platyhelminthes, having dorsoventrally flattened body hence are flat worms.

b) Hydra and Obelia are cnidarians belongs to phylum coelenterata and exhibit two basic body forms i.e, polyp and medusa. Sea walnuts belongs to phylum ctenophora and bears comb plates.
c) Homiothermous are warm blooded animals which maintains a constant body temperature and includes aves and mammals.
d) Platyhelminthes have incomplete digestive system as they absorb nutrients from the host directly through their body surface.
So, the correct answer is option B.
