When soil in the digestive tract of an earthworm leaves the crop, where does it pass?

Back 8

to the gizzard

Front 9

The movement of earthworms require all of the following:

Back 9

1) muscles lining the interior body wall
2) muscle contractions
3) traction provided by setae

Front 17

T/F Cephalopods are the most intelligent of all invertebrates.

Back 17

TRUE

Front 18

T/F Some annelids have fleshy appendages called parapodia.

Back 18

TRUE

Front 19

T/F The muscular regions that provide movement for a mollusk are called parapodia.

Back 19

FALSE

Front 20

T/F Polychaetes are terrestrial worms that tunnel through the soil.

Back 20

FALSE

Front 21

T/F Earthworms are hermaphrodites.

Back 21

TRUE

Front 22

What are the tiny tubular structures in mollusks called that filter useful materials from their coelomic fluid?

Back 22

nephridia

Front 23

What happens when the addutor muscles of a bivalve contract?

Back 23

they cause the valves to close forcefully

Front 24

How do bivalves feed?

Back 24

by sucking sea water through hollow tubes called siphons

All mollusks EXCEPT bivalves have a rasping tonguelike organ called a

Back 25

radula

Front 26

What type has a primitive brain called a cerebral ganglion located in one anterior segment?

Back 26

Annelids

Front 27

Back 27

they both lack parapodia and setae

Front 28

larval form shared by both mollusks and annelids

Front 29

Why are terrestrial snails more active when the air around them is moist?

Back 29

thin membrane in shell must be kept moist for respiration to occur
