Vertebrates
Organisms with a backbone.
What are vertebrates?
The three classes of fish.
What are jawless, cartilaginous, and bony?
Amphibians live part of their lives in both of these types of environments.
What are land and water?
The physical characteristic that allows reptiles to live their entire lives on land.
What is waterproof skin?
Endothermic vertebrates that have wings, beaks (or bills), feathers, and lay eggs.
What are birds?
A mammal's diet depends on the structure of these sensory organs that are found in their mouths.
What are teeth?
A behavioral or physical characteristic that helps an animal it survive in its environment.
What is an adaptation?
The organs that allow fish to exchange carbon dioxide and oxygen.
What are gills?
Amphibian females lay their eggs in this area, where they are fertilized by males.
What is water?
The three-chambered organ where Oxygen mixes with the blood (which is carrying Carbon Dioxide).
What is the heart?
This evidence supports the theory that birds are closely related to dinosaurs.
What is fossil evidence?
These types of glands are found within female mammals and produce milk for the young.
What are mammary glands?
An animal whose body temperature changes with the environment.
What is an ectotherm?
or
What is a cold-blooded animal?
The bony material that covers and protects the skin of a fish.
What are scales?
The three major groups of amphibians.
What are Newts/Salamanders, Frogs/Toads, and Caecilians?
Reptiles' body temperatures change with the environment, which categorizes them as these.
What are ectotherms?
or
What are cold-blooded animals?
The two types of feathers birds have.
What are contour and down?
The three different types of mammalian diets.
What are herbivores, carnivores, omnivores?
An animal whose body has the ability to maintain a consistent internal temperature.
What are endotherms?
or
What are warm-blooded animals?
The main appendages that allow fish to carryout locomotion (move).
What are fins?
The three-chambered organ, where Oxygen mixes with the blood (which is carrying Carbon Dioxide).
What is the heart?
The three main groups of reptiles.
What are Crocodiles/Alligators, Lizards/Snakes, and Tortoises/Turtles?
The reason penguins (flightless birds) are such good swimmers.
The three types of mammals.
What are monotremes, marsupials, placental mammals?
Although fully-grown vertebrates can look and very different, their embryonic stages are quite similar. The reason for this is because they all share this.
What is a common ancestor?
The organ that inflates and deflates with air to help it move up and down in the water.
What is the swim bladder?
A series of body changes that occur in amphibians, altering the way they live their lives (environment, breathing, etc.)
Ex: Tadpole changes into a Frog
What is metamorphosis?
Reptiles lay these type of eggs that keep the embryo moist and protected, even on dry land.
What are amniotic eggs?
Evolutionary adaptations for flight in birds.
What are strong/hollow bones, high-energy diets, large/efficient hearts, air sacs, and wing shape?
The three different types of teeth that help humans eat various types of foods.
What are incisors, premolars, and molars?
