A+|100% Correct
What drives evolution more quickly-- sexual or asexual reproduction? Sexual
Differences between carnivores, omnivores, and herbivores Carni= meet
Omni= both
Herb= both
Suspension Feeding Feeding on particles of organic matter suspended in the water
Deposit Feeding Feeding on small specks of organic matter that have drifted down and
settled on the bottom
Filter Feeding Sieves small food items from water.
Two requirements for a vertebrate - Vertebrate
- Skull (not necessarily a bone)
Three classifications for marine fish - Agnatha (jawless)
- Chondrichthyes (cartilaginous fish)
- Osteighthyes (bony fish)
Hagfish - Feeds on dead and dying fish and marine animals
- Produce lots of mucous in glands to protect them
- Jawless
Lamprey - Also jawless
, - Not slimy
- parasites on other organisms
Cartilaginous vs bony fish Cartilaginous
- teeth-like scales
- gills exposed to environment
- cartilege skeleton
- mouth on underside
- gills exposed to the environment
- electric signal pickup
Bony
- bony skeleton
- plate-like scales
- Mouth in front
- plate covers gills
Lateral Line Series of pores and canals lined with neuromasts that are specialized to detect
VIBRATIONS
Electric Sensors Detect living prey by sensing their neurons
Ovipary Egg laying
Viviparious Live birth
Oviviparous Kept inside of mother in an egg until right before hatching
