| Question | Answer |
|---|---|
| Do animals make their own food | No, they are heterotrophs |
| What is the thing that all animals start from? | blastula |

| Aquatic arthropods exhange gases through | gills are used in what organisms? |
| Air enter an insects body through __________ then passes through | spiracles, trachael tubes |
| Crabs, lobsters, shrimps, and crayfish are members of the class | crustacea incluedes these organisms |
| What are the basic body segments of an arthropod | the head, thorax and abdomen are parts of what? |
| The phylum that means "spiny skin" | echinodemata |
| Tube feet are part of the echinoderm's | water vascular system includes this structure |
| replace ment of regrowth of missing parts happens in waht organism and is called what | regeneration, echinodermata |
| This struchture is found in )) and is used for scraping food from surfaces | gastropods, radula |
| A starfish can hold tightly to the surface it is touching because of the | tube feet allow what? |
| An animal whose mouth is formed from the blastopore | protostone |
| A skeletal system in which muscles are supported by a water filled cavity | hydrostatic skeleton (def) |
| Type of asex reproduction where a new individual develops from an unfertilized egg | parthenogenesis |
| What are the functions of tube feet? | locomotion, exchange of gasses, excretion |
| Most arthropods have what kind of circulatory system? | open |
| what kind of eyes detect slight momements? | compound |
