| Question | Answer |
|---|---|
| Classification groupings in order | Kingdom, Phylum, Class, Order, family, Genus, Species |
| 98% of animal species, radial and bilateral symmetry, no backbone or cells walls | Invertebrates |
| 2% of animal species, bilaterial,internal skelton,sensory organs, nervous & respitatory | Vertebrates |
| Protomsome | 1st opening that develops from blastopore becmes a mouth. |
| Deutersome | Mouth develops from the second opening and the anue develops from blastopore |
| Coelomate | "true coelom",have a fluid filled body cavity completelty surrounded by tissue from mesoderm |
| Acoelemate | solid bodied; lacking a cavity between the gut and outer wall. NO BODY CAVITY |
| Pseudocoelomate | body cavity lined by tissue derives from mesodern and ednoderm; not completely lined. |
| Asymmetry | no line of bisection exists that could devide the organism into similar-looking halves |
| example of asymmetry | phylum Poriefera |
| Radial symmetry | where more than one hypothetical bisection can be visualized. |
| example of radial symmetry | Cnidaria; Echinodermata |
| Bilateral symmetry | only one hypothetical bisection can be visualized. |
| example of bilateral symmetry | phyla of most animals |
| trichinosis | food-borne disease caused be a microscope parasite. Undercooked meat; ex. hookworm |
| a tapeworm | undercooked meat; ingested; from feces of person or animal with tapeworm. |
| blood fluke | burrow into the skin; feed on blood; from irrigation in tropical warm regions (Africa) |
| What are heartworms in pets? | parasitic worm spread by mosquitoes. |
| What phylum is heartworms in? | nematoda |
| Where are hookworms found? | In warm moist tropical and subtropical climates |
| How can humans and pets attact hookworms? | Coming into direct contact with contaminated soil. ex. walking barefoot; swallowing soil |
| Complete metamorphois; 88% of all insects go through | Egg- Larva -Pupa- Adult |
| Incomplete metamorphosis; only around 12% go through | Egg- Nymph- Adult |
| Arachnids | scorpions, spiders, ticks, mites |
| Crustaceans | shrimp, crabs, lobsters, barnacles |
| Bivalves | clams, mussels, scallops, oysters |
| Insects | fly, ant, lady bug, termite |
| flatworms | tapeworms, flukes, planaria |
| cnidarians | jellyfish, coral, hydras, sea anemones, portuguese "man-of-wars" |
| Cephalopods | Squid, cuttlefish, octopus |
| Poriferans | sponge |
| Nematodes | roundworms rotifers |
