Reptiles
The reason snakes stick out their tongue.
To sense chemicals in the air, which helps them understand their surroundings.
The function of the keel in a flying bird.
A place for muscles in the chest and wings to attach.
Characteristics that separate the mammal brain from brains of other vertebrates.
Cerebrum and cerebellum have gyri and sulci
Function of the yolk.
Provides nutrients to the embryo-food source.
The determining difference between a turtle, tortoise, and a terrapin.
Turtles mostly in water, tortoise is on land, and Terrapins live in water and on land.
Features that separate Crocodilians from other reptiles.
Four chambered heart, scutes on skin, elongated snout with eyes and nostrils on top.
Characteristics the central shaft of a feather has with a flying bird's bones.
They are both hollow with support structures
Number of placentas in a mammal if they give birth to seven babies.
7
Functions of the albumin.
Nutrients (water and protein) and shock absorption and cushion. Protection against microbes that enter the shell.
The different ways constrictors, venomous, and non-venomous snakes kill their prey.
Constrictors suffocate, venomous inject venom, and non venomous bite and might have a mild toxin in their saliva.
The three things lizards have that snakes don't.
Legs, external ears, and eyelids
Three types discussed in Chapter 11 and which has the least barbule interaction.
Downy, flight feathers and tail feathers. Downy have the least barbule interaction.
Define diphydonty.
The condition in which a set of primary teeth is later replaced by secondary set.
The structure that stores waste from the embryo and facilities respiration.
Allantois
Difference between the way reptiles and mammals breathe compared to the way birds breathe.
Mammals and reptiles use bidirectional respiration, while birds use unidirectional
Two characteristics that separated members of the squamata from the other reptiles.
Skin is covered in scales and they can move both their upper teeth and lower jaws.
Definition of plumage.
All feathers of a bird, including their types, coloration, and arrangement.
True or false, does baby's blood ever mix with the mom in the placenta. Why or why not?
No because of amazing design. Mothers immune system could kill the baby if mixing happened.
As the embryo grows, this happens to the size of the yolk, and the allantois.
Yolk gets small while the allantois gets bigger.
Characteristics and function that differ in the feet of raptors, song birds, and waterfowl.
Raptors have claws (talons), songbirds have 3 toes in one direction and one in the opposite to grip branches, water owl have webbed feet.
Three characteristics that separate the only genus in the order Sphenodontia from other reptiles.
Tuataras have spines on their back all the way to the end of their tail, two rows of teeth in upper jaw and only one in lower jaw, and a pineal eye.
The structures that make up the vane, the structure attached to the central shaft, and the structure that can have hooks on a bird feather.
The vane is made up of barbs and barbules. Barbs attach to the central shaft, and barbules can have hooks.
If a baby animal is born alive, but is very small and not-well developed, according to the book which of the three types of mammals probably produces it. Explain.
Marsupial. Monotremes lay eggs, so there babies are not born alive. Placental mammals usually give birth to well developed babies because they get nutrients in the mother. Marsupials development takes place in a pouch after they are born.
Structures in the amniotic egg that are similar to placental mammals.
Chorion, amnion, and allantois are modified and called the placenta or chorioallantois placenta.
Differences in ways to nourish the babies of placental mammals, monotremes, and marsupials.
Placental mammals with placenta (well developed), monotremes lay eggs (not well developed), and marsupials give birth to not well developed babies that will develop in pouch or marsupium
