Multiple Choice skip

1. Lateral Line System
   1. FreshWater Fish - blood has a high concentration of salt, fish must constantly urinate to keep up with water osmosis into body
   2. Marine Fish - blood has low salt concentration, due to osmosis of water out of body, fish my drink a LOT
   3. earstones - 3 pairs in skull in fluid filled spaces for feeling pressure and orientation
   4. Pharangeal Gill Slits
   5. pores with many tiny hairs for pressure sensitivity
2. Gills
   1. Pockets in lungs of fish, large surface area.
   2. Marine Fish - blood has low salt concentration, due to osmosis of water out of body, fish my drink a LOT
   3. pores with many tiny hairs for pressure sensitivity
   4. Can make parts of body 5-10 degrees C warmer than environment (ex: tuna)
   5. Fillaments, large blood supply, large surface area
3. Buccal Pumping
   1. Gas Chamber that assists with bouyancy
   2. notochord, dorsal hollow nerve cord, segmented muscular post-anal tail, Endostyle
   3. Gas bladder directly connected to the gut, to increas air : breathe in, to release air: fart
   4. FreshWater Fish - blood has a high concentration of salt, fish must constantly urinate to keep up with water osmosis into body
   5. Opercula pumps to take in water through mouth, stationary respiration
4. Phylogenies
   1. Head Chordates : Amphioxins (lancelets)
   2. earstones - 3 pairs in skull in fluid filled spaces for feeling pressure and orientation
   3. Marine Fish - blood has low salt concentration, due to osmosis of water out of body, fish my drink a LOT
   4. Pharangeal Gill Slits
   5. Evolutionary history of Taxa
5. How do fish without Gas Bladders regulate?
   1. hair filled pores of the lateral line system
   2. Gas Chamber that assists with bouyancy
   3. Reproductive ties - a species is a population or group of populations that interbreed
   4. Sharks - liver oil (buoyant) light weigh skeleton (cartilage) must move to stay afloat.
   5. Electrical Detection
