Question

The combination of a true coelom and repeating body segmentation allows the annelids to do which of the following that anatomically “simpler” worms cannot ?

(a) Move through loose marine sediments

(b) Attain complex body shapes and thus locomote more precisely

(c) Feed as external parasites on other animals

(d) Be hermaphroditic

Answer 1

Correct option: (b) Attain complex body shapes and thus locomote more precisely

Explanation:

Annelids have successfully combined true coelomic cavities and repeating segmentation to more precisely control body movements compared with the anatomically simpler worms.
