Answer 1

Presence of 'metameric segmentation' is one of the 'most significant' characteristics of Annelida.

EXPLANATION:

Metameric represents the animal body with repetition of 'organs' and 'tissues' at some intervals, thus dividing the body in to linear series of 'similar parts', mostly noticed in Annelida.

It is crucial feature since it results in metameres which are fused in repetitive form which are directly visible, but other types lack such visible discrete module. These repetition helps in probably more helpful for locomotion process. This is exhibited by earthworms.

Answer 2

Answer:

• Presence of metameric segmentation is one of the most significant characteristics of Cestoda tapeworms.

• Zoologists have defined the concept metamery to be mesodermal event which is resulting in the repetition of the subdivisions of its units in a serial manner and these are ectoderm and mesoderm products.

• The segmentation is not similar as metamerism is.

• A metamerism styled segmentation is limited ectodermally or is derived by the tissue.
