2 What % of all animals are arthropods and what does the word “Arthropoda” actually mean?
3
80% of all animal species are arthropods
3 80% of all animal species are arthropods “Jointed Legs”
4
What is an advantage and a disadvantage of the compound eye?
4 What is an advantage and a disadvantage of the compound eye?
5
Advantage – Ultra wide viewing angle
5 Advantage – Ultra wide viewing angle Disadvantage – Poor image resolution
6
6 What is the name of the process by which arthropods shed their exoskeleton and why is the shell initially soft?
7
7 The process is called molting. The shell remains soft initially so the animal can have a chance to grow before the shell oxidizes and gets hard.
8
Compare & contrast complete and incomplete metamorphosis
8 Compare & contrast complete and incomplete metamorphosis
9
9 Incomplete – 3 stages (egg, nymph, & adult) where the nymph looks like the adult but wingless Complete – 4 stages (egg, larva, pupa, adult) where the larva looks nothing like the adult

10 What are the various forms of respiration that can be found in members of the five Subphyla of arthropods?
11
Trilobita & Crustacea – Gills Chelicerata – Book lungs

14 Daily Double What is the name of the extinction event that killed the trilobites, how long ago was it, what was the cause of the extinction, and what two Eras of the Phanerozoic Eon were divided by this extinction event? Daily Double
15
15 The Permian-Triassic extinction event occurred 250 mya and was caused by a super volcano that erupted in what is now modern-day Siberia. This event was the division point between the Paleozoic and Mesozoic Eras

18 How has the study of trilobites led to a better understanding of plate tectonic theory?
19
19 Since trilobite fossils have been found on the top of Mt. Everest, it shows that Mt. Everest was once underwater and that the Earth is a dynamic and ever-changing planet.

Distinguish between chelicerae & pedipalps
32 Distinguish between chelicerae & pedipalps
33
Chelicerae – mouthparts usually adapted into fangs
33 Chelicerae – mouthparts usually adapted into fangs Pedipalps – appendages used to grasp food and bring towards the mouth
34
34 Distinguish between neurotoxins and necrotoxins and give an example of a spider that has each type of venom
35
35 Neurotoxin – toxin that blocks the signals from the brain usually resulting in death by suffocation (black widow) Necrotoxin – toxin that destroys flesh and causes local cell death at the bite site (brown recluse)
36
36 What types of organisms are found in the following Chelicerata Classes: Eurypterida Xiphosura Pycnogondia
37
Eurypterida – Giant sea scorpions Xiphosura – Horseshoe crabs

42 What does the word “Hexapoda” actually mean and what type of organisms are considered hexapods?
43
Hexapoda means “six legs” and the hexapods are commonly
37 Hexapoda means “six legs” and the hexapods are commonly known as insects
44
44 From what Arthropod Subphylum did the insects most likely evolve and how did this evolution proceed?
45
The hexapods evolved from the myriapods.
45 The hexapods evolved from the myriapods. The elongated body of myriapod ancestors broke into three regions. The legs on the head region evolved into complex mouthparts, the three pairs of legs on the thorax grew large enough to support the whole body, and the legs on the abdomen reabsorbed into the organism as it evolved.

Straight Wing = Orthoptera Membrane Wing = Hymenoptera
49 Straight Wing = Orthoptera Membrane Wing = Hymenoptera Half Wing = Hemiptera Same Wing = Homoptera Two Wing = Diptera Shield Wing = Coleoptera

50 Describe how a honeybee’s waggle dance can show other bees where food is located?
51
51 Direction – The angle of the dance offset from the perpendicular of the hive is the same angle the bee flies offset from the sun outside. Distance – The length of time spent during the waggle portion of each dance cycle. One second = 1 km
