"to shed an old outer covering so that it can be replaced with a new one"
Molt
100
What benefits do earthworms give the plants in the soil that they inhabit
they mix the soil, recycle nutrients and bring up more minerals
100
What is a spider that has a bite that can be, but rarely is, fatal to humans?
Black Widow or Brown Recluse
100
If you count the cephalothorax as one body segment, how many major segments does an arthropod with a cephalothorax have?
Two
200
What type of symmetry does this have?
Spherical
200
A body covering, typically made of chitin, that provides support and protection
Exoskeleton
200
Name at least 4 parts of the earthworm that we discussed last week
Ganglia
Pharynx
aortic arches
esophagus
dorsal blood vessel
intestine
seminal vesicle
ovary
oviduct
gizzard
ventral nerve cord
oviduct
seminal receptacles
200
What are the stages of complete metamorphosis?
egg, larva, pupa, adult
200
If an arthropod did not have any predators living in it's ecosystem, would it still need an exoskeleton?
Yes it needs it for the support of the body.
300
An organism with this symmetry can only be cut into two identical halves by a single longitudinal cut along the center-right and left halves.
Bilateral
300
These are divided into these three segments-
Thorax, Abdomen, and Cephalothorax
Arthropods
300
which Phylum are earthworms a part of
Annelida
300
List at least 2 characteristics of Arachnids
Four pairs of walking legs
A cephalothorax instead of separate head and thorax
Usually four pairs four simple eyes
No antennae
Respiration done through organs known as "book lungs"
300
If an arthropod could not taste but the rest of the nervous system is operational, what sensory organ is malfunctioning?
antennae
400
Posessing both male and female reproductive organs. An Earthworm is this.
Hermaphroditic.
400
An eye made of many lenses, each with a very limited scope.
Compound Eye
400
If an earthworm's mouth is fully functional but it cannot ingest soil, what organ is malfunctioning
Pharynx
400
What are the functions of tube feet?
locomotion, respiration, circulation
400
A crayfish loses its claw in a fight. What happens?
It grows back
500
How are Fungi different from animals
Animals ingest their food while fungi absorb their food after external digestion
500
List at least 4 parts of the crayfish:
Antennae
Antennules
Cephalothorax
abdomen
telson
uropods
swimmerets
carapace
chelipeds
eye
walking legs
500
What process will stop if the earthworm's cuticle dries up
Respiration
500
What are two differences between "centipedes" and "millipedes"?
Millipedes have many more legs
Each of millipedes body segment has 2 pairs of legs
Millipedes' bodies are rounded, rather than flat
Millipedes' antennae are shorter
Millipedes don't have venomous claws
Centipedes are fierce predators, while millipedes are docile
500
Why do we say that arthropods are constantly bleeding internally?
They have an open circulatory system, and blood flows directly onto the tissue from the arteries
