1.Vertebrates are chordates which have: (1)a dorsal tubular nerve cord
(2)a dorsal supporting rod, called a notochord
(3) a postnatal tail,
(4)pharnyngeal pouches that become gill slits
2.Two types of invertebrate chordates are: urochordates and
cephalochordates
3.urochordates: tunicates or sea squirts come in varying sizes and
shapes but have incurrent and excurrent siphons, gill slits are the only
chordate characteristic in adult tunicates.
4.cephalochordates: lancelets are small, fishlike animals that occur in
shallow marine waters in most parts of the world. they spend most of
their time buried in the sandy bottom, with only anterior end
projecting.
5.evidence that birds are reptiles: birds: -have feathers, which are
modified scales.
-have scales on their feet.
-and reptiles both lay eggs
-and reptiles have similar internal organs
-and reptiles also show some skeletal (skull) similarities
6.Why isnt a lancelet a vertebrate: retains the notochord as an adult and
has no vertebrate
7.which group of vertebrates are fully adapted to life on land?: mammals
8.In a frog the glottis allows air to enter the: trachea
9.In the frog the esophagus allows food to enter the: stomach
10.In the frog the cloaca receives material from the: kidneys, oviducts
and mesophoic ducts
11.in the frog the sperm reach the cloaca by way of the: urinary ducts
12.What is the difference between the heart of a frog and that of a pig?:
frog has one ventricle and a total of three chambers
pig has two ventricles and total of four chambers
13.A pulmonary circuit is seen in verterbate animales adapted to life on
land: pulmonary circuit takes blood to an dfrom the lungs; lungs
adaptation of life on land
14.What is the major difference between the respiratory system of a perch
and that of a frog, a pigeon, and a pig: -perch breathes with gills while the
other animals being terrestrial breathe with lungs
15.pulmonary system: has lungs
16.branchial system: involves gills
17.the perch, pigeon, and pig have a nearly impenetratable covering. why
