Kids Play Constantly On Family Game Systems


To be honest, I cant remember at all what happened In class because Saturday and Sunday I was performing at a café called Premier with “Ormi Orchestra” (my brothers band) but I can tell you exactly what was discussed.

Chordate Characterisics
1)Notochord- supportive rod thru the dorsal side
2)Pharyngeal Gill Slits – Present at some point in development
3) Dorsal Hollow Nerve Cord
NOTEEEFSGOIJSG* not all chordates are vertebrates

Chordate Classes
-Agnatha – jawless fish+eel like+no scales+sucker-like mouth+some parasitic
-Chondricthyes – cartilage+fish/sharks+true jaw+Non-covered gill slits+Spikey scales
-Osteichthyes – holes-boney fish+swim bladder+gull cover (operculon)
-Amphibiea – begin life underwater using gills, adults have lungs, moist skin,external fertilization needs water
-Reptilia- Mostly terrestrial+First amniotic+dry scaly
-Aves – “aviation”-Birds-feathered bodies w/ scales on feet+endothermic+lungs+wings-MOST fly)
-Mammalia – Hair covering body+fat under skin+Mammary glands+Endothermic

REPRODUCTIOOONNNNN
-Shift from internal/external fertilization
-Oviparous – parents lay eggs OUTSIDE of body
-Ovoviviviviviparous – animals develop inside mother
+nourished by EGG
+born alive
-Viviparous – animals are nourished by mother and born alive. THAT’S US!!!

Body Temperature
-Ectothermic – rely on behavior to control body temperature
-Endothermic – can generate and retain heat
+uses a lot of energy
+have insulation
