Question

For the following questions, the entire statement must be true or the entire statement must be false. Choose the best answer for each. During initial developmental processes, protostomes like the arthropods undergo radial cleavage and have indeterminate cleavage where the fate of each cell is more fixed. The roundworms, such as those found in soil and parasitic ones like Ascans, are included in the phylum Nematoda. Chitinous setea (or chetae) can be found as a few small, bristle-like appendages in the earthworm. One organism that undergoes torsion during development is the nematode. The coelacanths and lungfishes are both lobe-finned fishes.

Explanation / Answer

11]

During initial development processes protostomes like the arthropods undergoes radial cleavage and have indeterminate cleavage where the fate of each cell is more fixed

It is false

A member of one of two distinct evolutionary lines of arthropods, characterized by spiral, determinate cleavage, which is a type of embryonic development in protostomes that rigidly casts the developmental fate of each embryonic cell very early

12]

The roundworms such as those found in soil and parasitic ones like Ascaris are included in the phylum nematode

It is true

Adult Ascaris found in human small intestine but eggs are found in soil.

13]

Chitinous setea or chetae can be found as a few small bristle like appendages in the earthworm

It is true

14]

One organism that undergoes torsions during development is the nematode

It is false

One organism that undergoes torsions during development is the snails.

15]

The coelacanths and lungfishes are both lobe-finned fishes

It is true
