(Each question worth 50 points.)

A living vertebrate is endothermic. Is it possible that the vertebrate is a reptile? Why?
No, living reptiles are ectothermic. Some scientist speculate that some extinct reptiles might have been endothermic.
What are the 3 features that allows birds to fly?
feathers, wings, and skeletal structure.
Name a mammal's 2 types of hair. Which one serves as insulation?
guard hair and underhair
underhair
On page 576 of your text book, what are the following parts of the amniotic egg called? e, f, g, h, i (Each one is worth 40 points.)
e- chorion
f-yolk sac
g-yolk
h-albumen
i-shell
Alligators and Crocodiles make up order _________. When a ___________ mouth is closed, you cannot see its teeth. ___________teeth can be seen even when the animal's mouth is closed.
Testudines
Alligator
Crocodile
Name at least 4 of the 6 types of dinosaurs named in the book that scientists have put into groups.
Apatosaurus, Stegosaurus, Triceratops, Tyrannosaurus, Plesiosaurus, Pteranodon.
Why don't birds molt like reptiles do?
If birds lost all of their feathers at once like reptiles lose all of their skin, they wouldn't be able to fly until all their feathers grew back.
Give the definition of gestation.
The period of time during which an embryo develops before being born.
Scales prevent ____________ and they ____________. Since scales are not made of living tissue, reptiles must ___________ in order to grow. (Each blank worth 100 points.)
water loss, insulate, molt
Lizards and snakes are found in order ___________. Lizards have ears and can hear, while snakes are ______. Lizards have the same type of scales all over their bodies, while snakes have specialized scales on their bellies for _________. Most lizards have _________ and can therefore close their eyes, but snakes can not.
deaf
locomotion
eyelids
What are the 2 main problems scientists encounter when tryin to study dinosaurs?
1. No one living has ever seen a dinosaur.
2. The meniscal amount of data we have are from fossilized remains.
What was God's purpose for having swimming birds produce oil while preening?
So these birds can dry quickly after leaving the water.
What is the main difference between offspring born after a long gestation period and offspring born after a short gestation period?
Offspring born after a long gestation period are more developed than those born after a short gestation period.
An amniotic egg is covered in a protective shell. The _________ grows around the embryo, forming a fluid-filled sac in which the embryo floats. The yolk sac contains the yolk, which feeds the embryo. The ________ is a sac of blood vessels that allows for the respiration and excretion of the embryo. The _________ is a membrane that envelopes these 4 structures. The albumen protects the embryo from infection, is a store house for water, provides mechanical support for the chorion, and stores proteins, which can be broken down into amino acids that the embryo can use in ____________. (Each blank is worth 100 points.)
amnion
allantois
chorion
biosyntheis

A snake has 2 nostrils for smelling, but it augments this sense with sensory pits called Jacobson's organs. When a snake sticks out its tongue, it collects chemicals suspended in the air. It pulls them back into their mouth, transferring them to the Jacobson's organs, which sends signals to the brain.
Name 3 characteristics that all members of class Aves have in common.
endothermic, heart with 4 chambers, toothless bill, oviparous laying an amniotic egg that is covered in a lime-containing shell, covered in feathers, and skeleton composed of porous, light weigh bones.
What are the scientific differences between down feathers and contour feathers?
Down feathers are smooth with barbules but no hooked barbules. Contour feathers are feathers with hooked and smooth barbules, allowing for barbules to interlock.
Since most mammals are viviparous, the embryo is attached to the mother by a _________. The nonplacental mammals, however, are either _________ or their embryos develop in a _________. The length of the _______ ________ determines how well developed the offspring is when it is born.
placenta
oviparous
pouch
gestation period
Reptiles have what 6 characteristics in common?
1. covered with tough dry scales
2. ectothermic
3. breathe with lungs throughout their lives
4. 3 chambered heart with a ventricle that is partially divided
5. produces amniotic eggs covered with a leathery shell
6. most oviparous but some ovovivpaours
What is the difference between neurotoxins and hemotoxins?
Neurotoxin is a poison that attacks the nervous system and is fast-acting (causing blindness, paralysis, or suffocation). Hemotoxin is a poison that attacks the red blood cells and blood vessels and is slower-acting (destroying circulation).
Name the other 3 characteristics, not mentioned before, that all members of class Aves have in common.
endothermic, heart with 4 chambers, toothless bill, oviparous laying an amniotic egg that is covered in a lime-containing shell, covered in feathers, and skeleton composed of porous, light weigh bones.
Birds like quail and other game birds have tender white meat composed of their flying muscles, predominantly around the breast. Why is this meat (that we eat) white in color and not darker like other parts of the bird we eat?
These feathers receive less oxygen, which means they have less myoglobin, a compound used to store oxygen in muscles. It is the lack of myoglobin that causes this meat to be a white color.
