27
What animals are in the subphyla Hexapoda
Insects
28
What are the classes in Arthropoda
Chilopoda Diplopoda Insecta
29
How can you tell a centipede from a millipede
Centipedes have 1 pair of legs/ segment | Millipedes have 2 pairs of legs/ segment
30
What is the difference between hemimetabolous and holometabolous metamorphosis?
Hemimetabolous is when it doesn't morph into a whole new body from but holometabolous does
31
What is the nerve ring for Echinodermata?
The nervous system ring where branches arise from
32
What is the water vascular system in Echinodermata?
Central ring where five radial canals extend out of the body and arm canal it uses hydraulic power to operate a multitude of tiny tube feet for locomotion and food capture
33
What is the madreporite in Echinodermata
Sieve-like plate on the animals surface, and flows through a tube to the central ring canal
34
What is the radial canal in Echinodermata
Extends from the ring canal
35
What are the lateral canals in the Echinodermata
Muscular sacs that lie at the base of tube feet
36
What is the ampulla in Echinodermata
Lie at base of tube feet and when they contract the fluid is prevented from entering the radial canal by a one way valve
37
What is the tube foot in echniodermata
Where fluid is directed from the ampulla, fluid makes it extend for locomotion
38
What are the ossicles in Echinodermata
Calcium- rich dermal plates
39
What are the four classes of Echinodermata
Asteroidea Ophiuroidea Echinoidea Holothuroidea
40
What animals are in the class Asteroidea
Sea stars
41
What animals are in the class Ophiuroidea
Brittle stars and basket stars
42
What animals are in the class Echinoidea
Sea urchin, sand dollar
43
What animals are in the class Holothuroidea
Sea cucumbers
44
What are the four characteristics of Chordata?
Notochord Dorsal hollow nerve cord Pharyngeal Slits Postnatal Tail
45
What is a notochord of Chordata?
Flexible cartilaginous rod that supports body, anchors muscles, and allows fast movement
46
What is the dorsal hollow nerve chord in Chordata
Differentiates into brain and spinal chord
47
What are the pharyngeal slits of Chordata
Aid in filter feeding or gas exchange
48
What is the postnatal tail in Chordata
Extends beyond the anus and provides thrust in water or balance on land
49
What is the incurrent siphon of the Chordata
Foot particles utters the tunicates through the in current siphon which is connected to the pharynx
50
What is the endostyle in Chordata
Mucous sheets secrete from it
51
What is the excurrent siphon in Chordata
Where excess water exits
52
What are the 3 subphyla of Chordata
Urochordata Cephalochordata Vertebrata
53
Urochordata
Tunicates Invertebrates Filter feeders Only retain pharyngeal slits
54
Cephalochordata
Lancelets Invertebrates All 4 characteristics are retained
55
Ecology
How biotic and abiotic factors interact with the environment
56

57
Consumers
Eat others | Heterotrophs
58
Primary consumers
Eat producers
59
Secondary consumers
Eat primary consumers
60

61
How much energy do we lose from each consumer
90%
62
Habitat of orangoutangs
Tropical and swamp forests of Borneo and Sumatra | Extremely arboreal
63
Diet of orangoutangs
Mostly fruit | Bark leaves and insects
64
Adaptations of orangoutangs
``` Long arms Great nest builders Mostly solitary Tools Problem solving + memory ```
65
Repetitive behaviors of orangoutangs
Rocking/ pacing Picking Regurgitate then eating
