What type of symmetry do Amniota exhibit?
Bilateral symmetry
Name any TWO members of Cnidaria.
Coral, jellyfish, sea anemone, jellyfish, comb jellies, Hydra, Obelia, etc.
What type of symmetry do worms exhibit?
Bilateral symmetry
The Corona in Rotifers are used for feeding and locomotion (T/F)
True- composed of a pair of ciliated dics (beating cilia)
Why are reptile skin thick and made of Keratin?
Less permeable to water (limits water loss)
Keartin protects from Physical damage
Tail and flight feathers are lost in pairs (T/F)
True: Balance
This phyla's members are sedentary.
Porifera
Compare the digestive tract of flatworms and segmented worms.
Flatworms have a digestive tract with one opening (entrance/exit), and segmented worms have a complete digestive tract with two ends.
The eggs of Ascaris are fertilized in the Oviduct (T/F)
False
Uteri
This group of animals push air from their cavities?
Amphibians (simple inner linings)
Reptiles expand their cavity via muscles
What is the single most defining feature of hairy mammals?
Mammary glands
What type of symmetry do members of Porifera exhibit?
Asymmetry (none)
Flatworms found in the phylum Platyhelminthes, such as Gyrodactylus, which are distinguished by being ectoparasites with a posterior attachment organ called a haptor.
Monogenea
What is the Copulatory bursa?
In Nematoda reproduction, the copulatory bursa (a wing-like structure or ray) is used to grasp female mates.
In non-volant reptiles, oroparus reproduction is defined as the abilty to ____________.
What is ????? Trick question, not a real word.
What is a major challenge Higher Vertebrate faced transitioning to land?
Physical Support
Environmental Extremes
Resource Scarcity
This taxa of invertebrates contains organisms that use a velum for rhythmic propulsion and a statocyst for spatial orientation (balance).
Hydrozoa
Cnidaria (or Phylum Cnidaria)
Campanulariidae
What Trematoda life cycle contains: Miracidium larvae, Rediae, Cercariae and metacercarial cysts?
Clonorchis sinensis
Platyhelminthes (Flatworm)
Clonorchiasis disease
Why are Ascaris coughed up and swallowed?
Immature Larvae must migrate through the lungs to mature before swallowing to survive the trip through the stomach.
Crocodiles secrete their nitrogenous waste as Ammonia (T/F)
False: Very young, purely aquatic crocodile hatchlings may excrete some ammonia, but this quickly switches to uric acid as they grow and become more terrestrial.
This term describes the primitive placenta found in marsupials, where the yolk sac is enlarged, contrasting with the more derived highly vascularised chorioallantoic placenta.
Choriovitelline Placenta
