Which of the following does not surround the developing embryo w an amniotic membrane?
amphibians
Which of the following have only one ventricle and one atrium?
shark
salt water, ray-finned fish tend to
lose water from their bodies to the environment
which of the following is generally true (for all of nearly all species) of chondrichthyes
they have deciduous homodont teeth
in the countercurrent system found in the gills, when the water first enter the gills
it encounters blood vessels carrying fairly well-oxygenated blood and low levels blood
the decline of the golden frog is due to
chytrid fungus, habitat destruction, and a disease that suffocates frogs
reproduction in animals that mate and lay eggs on land requires
extra membranes not found in animals that lay eggs in water
all snakes belong to
reptilia
reptiles that have a complete four-chambered heart and gizzard are found in the group
aves and crocodilia
in comparison to diapsids, all synapsids exhibit
4 chambered hearts, and endothermic thermoregulation (warm-blooded)
snakes are able to feed on objects longer than their head largely due to their modifications which include
kinetic jaws that are flexible w loose connections between each side of jaw
birds meet their high metabolic demand for oxygen partly by
storing air in posterior and the anterior air sacs during breathing cycles
characteristics that enable birds to fly include
hollow bones, reduction of weight in head, and asymmetrical feathers
you would anticipate hawks and gales (daytime hunters) to have
areas of densely packed cones in their eyes
other than waterfowl, if you found a bird species that was monogamous, you would meet logically guess that its young are
altricial
one example of special feeding adaptations in birds is that of a woodpecker, which has
a strong chisel-like bill and a long tongue apparatus that attaches all the way over its head and into its nostril
an opossum carries its premature babies in a pouch. It belongs to the
metapheria
the ornithodelphic are similar to birds in that they
lay eggs and have a cloaca
in the desert-living kangaroo rat, one would expect to find
a metapheric kidney and nephrons w very long loops
which of the following is not a characteristic of eutherian mammals
homodont teeth
the pic of blood flow represents
a and b are correct
if you were to list shared characteristics aves and crocodilia that are diff from other reptile groups you should include
nest building w parental protection, completely separated ventricles, and presence of a gizzard
an animal population in which females ovulate only once at a specific time of the year, exhibits what is referred to as
an estrous cycle
which of the following is not unique to mammals
endothermy
