200
A natural predator or disease released into an area to fight a harmful insect.
What is a biological control?
300
Describe the type of circulatory system that most mollusks have.
What is an open circulatory system: blood is not always in vessels, blood sloshes over the organs and returns to the heart?

3 major differences between arachnids and insects.
What are arachnid: 2 body sections, 4 pairs of legs, no antennae; insect: 3 body sections, 3 pairs of legs, 1 pair of antennae?

4 niches within a food chain.
What are producer (make own food), consumer (consume other animals or plants), scavenger (consume freshly dead organisms), decomposer (breaks down waste and decaying organisms)?
300
Life cycle of echinoderm.
What is female release egg/male release sperm into water, eggs are fertilized, swimming larvae undergo metamorphosis into adult?
300
Organ snails and slugs use to obtain food.
What is a radula?
400
Major differences between the 3 classes of mollusks. (body, movement, food)
What is gastropods: single/no external shell, obtain food with radula, move by creeping along with broad foot; bivalves: two shells held together by hinge, filter feeder, use foot to move slowly; cephalopods: foot adapted into tentacles around it's mouth, capture prey using tentacles and crushes with beak, swim by jet propulsion?
400
Differences between centipedes and millipedes.
What are centi: one pair of legs attached to each segment, more than 100 segments, swift predators that inject venom into prey; milli: two pairs of legs on each segment, scavengers, curl up into ball for protection, squirt foul smelling liquid at predator?
400
3 different types of mouthparts.
What are lapping/spongelike mouthpart, sucking/coiled tubed mouthpart, chewing/sharp edged mouthpart?
400
Differences between brittle and sea stars.
What is brittle: long, slender arms with flexible joints, no suction cups on tubed feet, move by moving arms in wavelike motion against ocean floor; sea: use tubed feet for movement catching prey?
