100
a hard cuticle that covers the body of an arthropod
What is exoskeleton
100
in terrestrial arthropods, these pores open to a series of finely branched air tubes within the body called trachea.
What is spiracles
100
Butterflies and moths have a coiled tongue called a *blank* that uncoils allowing them to drink nectar from flowers.
What is proboscis
100
A portion of the true coelom in echinoderms that has been adapted to serve as this unique network of canals that branch into these tiny structures that function in movement, gas exchange, feeding and excretion. (2 answers)
What is Water vascular system, tube feet
100
an ability to intentionally detach a body part such as a limb that will later regenerate exhibited by most echinoderms.
What is autotomy
200
functional units of arthropods formed from fused body segments.
What is tagmata
200
all species of chelicerata have a body consisting of two tagmata, a fused head and a thorax, which is called *blank*, and an abdomen
What is cephalothorax
200
The majority (85%) of insects undergo this change in the body that has four stages: egg, larva, pupa, and adult
What is complete metamorphosis
200
Many echinoderms have this internal hard skeleton composed of calcareous plates overlaid by a thin skin.
What is endoskeleton
200
a single flexible rod that lies between the digestive tract and the nerve chord in chordates.
What is notochord
300
independent visual units that make up the compound eyes of arthropods
What is ommatidia
300
appendages of chelicerata that have various sensory, predatory, or reproductive functions.
What is pedipalps
300
The rest of the insects undergo this change, in which the change is much more gradual.
What is incomplete metamorphosis
300
a sieve like plate on an echinoderm's surface where water enters the water vascular system
What is madreporite
300
early divergent chordates have these that function as a filter feeding device whereas in later divergent chordates they develop into gills for gas exchange.
What is pharyngeal slits
400
excretion is accomplished by these extensive tubes that extend from the digestive tract into the body cavity where they are surrounded by hemolymph, occur in insects and some other taxa.
What is Malpighian Tubules
400
a narrow, waistline point of attachment in spiders that joins the cephalothorax and the abdomen
What is pedicel
400
In many species of crustaceans, the cuticle covering the head extends over most of the cephalothorax, forming this head protective fold.
What is carapace
400
from the madreporite, the water flows into this structure located on the central disc, into five radial canals, and into the tube feet.
What is ring canal
400
tunicates are filter feeders and draw water through the mouth through this using a ciliated pharynx and filter it through extensive pharyngeal slits
What is incurrent siphon
500
Terrestrial arthropods have a highly developed *blank*
What is tracheal system
500
The study of insects
What is entomology
500
The first larval stage of crustaceans
What is nauplius
500
A sac at the base of each tube foot that stores water.
What is ampulla
500
Tunicates are enclosed in a nonliving *blank* made of protein and a cellulose like material called tunicin
What is tunic
