Homework Answers
Answer
COMMON NAMES
lug worms, fire worms, feather duster worms, palolo worms, clam worms, bristle worms.
CHAETAE
bundles of bristles, polychaete
PARAPODIA
vascularised parapodia are present
STRUCTURES AND MODES OF LOCOMOTION
Pair of vascularised parapodia in each segment covered by bristles are used for locomotion.
Also some crawl, some swim.
STRUCTURES &WAYS THEY FEED
mouth is situated on peristomium with jaws and pharynx, varies in form according to ways they feed. There are herbivores, filter feeders, scavengers, predators and parasites.
STRUCTURES/MODES OF DEFENCE
Speed and agility is used to avoid predators. Yellow bioluminescence is another defence mechanism. When attacked they produce glowing sparks to distract predators. Bristles also help in defence along with chitinous walls.
REPRODUCTION
Most species have separate sexes. Very few are hermaphrodites. Primitive forms lay eggs and fertilize externally. Very few copulate, that is internal fertilization. The young eventually metamorphose into adult.
SYNAPOMORPHIES
A characteristic present in ancestral species, shared exclusively by its descendants.
Phylum Annelids show synapomorphies as blastopore becomes mouth, true coelom via shizocoely, spiral cleavage, trochophore larvae. Polychaete is the class.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
