(2)triploblastic, worm like having symmetrical body
(3)diploblastic animals with tissue level organization​

Answer 1

Answer:

1-Echinodermata.

2-Annelida.

3-Coelentrata.

Answer 2

Answer:

The correct answers are the following:

1. Echinodermata
2. Annelida
3. Cnidaria

Explanation:

To identify the phyla from the given features, we needs to pin point over the main characteristics of each phylum.

1. in this subpart, given most important characteristic feature of identification is the radial symmetry, which is found only in Echinodermata. Other features further supports the identification. Example - Echinus.
2. In this subpart, most distinguishable character is the symmetrical body morphology, and given the keyword, worm. This identifies the particular phylum as Annelida, having bilateral symmetry. Example - Nereis.
3. In this subpart, diploblastic animal featuring better body organization at the level of tissue, characterizes as Cnidarians. Also known by the name of phylum Coelenterata. Example - Aurelia.
