4420752386	What distinguishes vertebrates from invertebrates	vertebrates have a internal segmented backbone.	1
4420752387	Which group contains the vast majority of animal species?	vertebrates.	2
4420752388	radial symmetry	body parts arranged in a circle around 1 axis. ex: starfish and jelly fish.	3
4420752389	bilateral symettry	can be split down the middle and have 2 mirrored sides. ex: human and dog	4
4420752390	Porifera (sponges)	characteristics: lack muscle and nerve cells. unable to move from where they are attached. ex: sea sponge.	5
4420752391	Cnidaria (Cnidarians)	ex: jelly fish, coral, and sea anemone 2 basic body forms: polyps and medusas characteristic: they sting prey and digest it	6
4420752392	playltyhelminthes (flatworm)	ex: tapeworms,planarians, flukes characteristics: absent gut, 3 classes include planarians, flukes, tapeworms.	7
4420752393	Mollusca (molluscs)	ex: garden snails, clams, squid gastropod- snails pelecypoda- clams cephalopoda- squid	8
4420752394	Annelida (segmented worms)	ex: earthworms, marine worms, and leeches segmented body, 3 groups include earthworms, marine worms, and leeches	9
4420752395	Nematoda (roundworms)	ex: hookworms, pinworms, guinea worms role: are parasites of nearly every animal and plant species.	10
4420752396	Echinodermata (echinoderms)	ex: sea stars, feather stars, sea lillies have a water vascular	11
4420752397	arthropoda (arthropods)	ex: rhino beetle, lobsters, scorpions	12
4420752398	phylum chordata	invertebrates chordates, fish, amphibians, reptiles, birds, and mammals.	13
4420752399	4 characteristics common to chordata	notochord hollow nerve cord pharyngeal slits tail	14
4420752400	what are the two groups of invertebrate chordates	tunicates and urochordates	15
4420752401	what do vertebrates have in common	large, active, brain encased in a hard skull	16
4420752402	describe the vertebrate endoskeleton and how they differ from exoskeleton	arthropods exoskeletons- outside of an animal and do not grow with the vertebrae, but shed. endoskeleton vertebrate endoskeleton- can change shape and size, built with bone and cartilage, and is more protective.	17
4420752403	unique fish charecteristics	gills and paired fins	18
4420752404	chondrichthyes	rat fish, shark, and ray. skeleton made of bone.	19
4420752405	osteichthyes	common name is bony fish and skeleton made of bone.	20
4420752406	two common amphibia	snakes and crocodile	21
4420752407	amphibians challenges	first mammals with four- used to paddle thru water water evaporates from their skin quickly- can absorb water through skin eardrum- evolved on gill limbs and lungs- successful for environments with poor oxygen.	22
4420752408	amniotic egg	waterproof container for the embryo. keeps embryo from drying out as it develops.	23
4420752409	endothermic animal	organisms use their own metabolic heat to keep warm.	24
4420752410	ectothermic animals	organisms whose body temperatures are determined by their environment.	25
4420752411	4 types of reptilla	eastern water dragon, crocodile, alligator, and lizard.	26
4420752412	oviparous animals	deposit their eggs into an external nest	27
4420752413	viviparous animals	keep the egg inside their body during development	28
4420752414	reptile adaptions	amniotic egg ectotherms dry scales (contain heat and absorb energy) many shapes and sizes	29
4420752415	bird adaptions for flying	hollow bones, fused "v-shaped" collarbones, hips, and feathers.	30
4420752416	4 main characteristics of mammals	hair, mammary glands, middle ear containing three bones, and jaw.	31
4420752417	describe the 3 major groups of mammalia	monotremes-lay eggs marsupials- eutherian- give birth to live young.	32
