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 is this an advantage in each case?: it
provide protections

, bio 152 lab 24
-Perch live in fresh water and prevent water from entering the body
-Pigeon and pig live on land and prevent H20 loss
18.A frog uses its skin for breathing: skin is thin and moist and allows gas exchange to occur
19.urogenital system: organ system of the reproductive organs and the urinary system
20.The cloaca receives material from: (1) mesonehoric ducts (2) ovidcuts and (3) large intestine
21.How does a frog locomote on land: hopping; the hind limbs provides the thrust for movement
22.What is a frog's means of locomotion in water?: swimming; the hind limbs provide thrust for movement
23.Both vertebrates and arthropods: are segmented specialization of parts
ahs occured
oth have jointed appendages both aquatic and
terrestrial
24.vertebrates: have endoskeleton
wo pair of appendages are characteristic brain is more complex
high degree of cephalization
25.What is the advantage of having separate ventricles: keep O2- rich blood from mixing with O2- poor blood.
26.Contrast the body temperature o fanimals having a four chambered heart to that of animals not having a
four chambered hear: animals with a four chambere heart are endothermic while those that do nothave a four
chambered heart are ecto thermic
27.What anatomical feature is present inthe pig and pigeon but issing in the frog: a frog has ribs but non
articulate with sternum; does not have rib cage. pig and pigeon have rib cage bc rib articulates with sternum
28.In a fish, the blood moves in: -a single loop
- the heart has a single atrium and ventricle, which pumps the blood into the gill region where gas exchange takes
place.
29.In amphibians and morst reptiles, have a: -double loop system in which the heart pumps blood to both the gills
and the body.
-has three atrium
30.In birds and mammals, (some reptiles): the right side pumps blood to the lungs, and the left side pumps
blood to the body
31.What animals studied have a separate circulatory system for the respira- tory organs: frog, pigeon, pig
