Question

The combination of a true coelom and repeating body segmentation allows the annelids (unlike the anatomically “simpler” worms) to do which of the following:

• A. Attain complex body shapes and thus locomote more precisely
• B. Move through loose marine sediments
• C. Be hermaphroditic
• D. Inject paralytic poisons into their prey

Answer 1

The correct option is A Attain complex body shapes and thus locomote more precisely

Annelids have successfully combined true coelomic cavities and repeating segmentation to more precisely control body movements compared with the anatomically simpler worms.
Segmentation of annelids allows them for more complex coordinated movement.
