Centipedes and Millipedes
WILD CARD
100
What are the main characteristics of arthropods?
segmented body invertebrates exoskeleton jointed appendages
100
How many antennae do crustaceans have?
2 pairs or 4. short and long antennae
100
How many pairs of legs does an arachnid have?
four pairs.
100
How many legs does a millipede have per segment.
two pairs or four legs.
100
what type of circulation does an arthropod have?
open circulatory system
200
What is the tough outer covering of an arthropod called?
exoskeleton.
200
The number of legs a crustacean has is...
5 or more pair/10 or more legs.
200
True or False: An arachnid has two pairs of antennae. If false, answer the question correctly.
What is false - they do not have antennae.
200
How many legs does a centipede have per segment? & Centipede OR Millipede? This arthropod injects venom into its prey.
one pair or two. Centipede.
200
What are the four groups of arthropods?
crustaceans, insects, centipedes and millipedes, and arachnids.
300
What is the function of an exoskeleton?
For protection AND so the arthropod does not dry out.
300
Where are the chelipeds located and what are their function?
on the first pair of legs, and they are used to capture food and defend itself.
300
How is an arthropod different from humans?
they breath out of the tracheal and body characteristics.
300
Malpighian tubules do what to the blood?
It extracts wastes from the blood and then adds them to feces or digestive wastes.
300
Do insects produce waste?
Most terrestrial insects produce uric acid as their main nitrogenous waste product. Uric acid is a relatively non- toxic and highly insoluble waste product. Therefore, it can crystallize out of solution, and may be either retained in the body, or eliminated as a solid waste material with little water loss.
400
What do the jointed appendages give arthropods the ability to do?
Move, obtain food, reproduce, etc.
400
How many segments do arthropods typically have?
the have 1, 2, & 3 body segments
400
Give two examples of an arachnid.
mites, ticks, scorpions, spiders.
400
Where do arthropods fit into the food chain?
TRICK QUESTION! they fit about everywhere with some being primary consumers such as grasshoppers to tertiary consumers like some centipedes
400
What is the process called when a arthropods sheds it exoskeleton for a new layer?
the moulting process
In arthropods, such as insects, arachnids and crustaceans, moulting is the shedding of the exoskeleton, which is often called its shell, typically to let the organism grow. This process is called ecdysis. Most Arthropoda with soft, flexible skins also undergo ecdysis.
500
The process of shedding an exoskeleton is called...
Molting.
500
Most crustaceans go through a process called _________ where they begin as larvae and develop into adults.
metamorphosis.
500
Describe how a spider kills and eats its prey.
A spider has hollow fangs through which they inject venom into their prey. The venom turns the tissues of the prey to mush, and the spider uses the fangs to suck in the food.
500
Are millipedes scavengers or predators?
scavengers.
500
What physical characteristics would help you to determine whether or not an arthropod was an arachnid or a crustacean?
pairs of legs (4 vs. 5 or more), body sections (2 vs. 2 or 3), pair of antennae (none vs. 2 pairs).
