Term | Definition |
Bird | warm-blooded vertebrates with feathers. Feathers keep the bird warm and dry |
Mammal | Warm-blooded , vertebrates with fur or hair. |
reptile | Cold-blooded vertebrates that live on land. dry, scaly, skin. breath through lungs. |
amphibian | Cold water vertebrates that spend some of their lives in water and part on land. Breaths through its skin. skin is moist Examples are frogs, toads, and salamanders. |
cold-blooded | body temperature changes with their surroundings. |
warm-blooded | animals whose body temperature does not change much. They get heat from breaking down food. Examples are mammals, birds |
vertebrate | A back bone. A back bone allows larger and heavier animal to move about |
How are you like fish, frogs, birds, and mice? | we all have a backbone |
How is a vertebrate different for an invertebrates? | a vertebrate has a backbone and an invertebrate does not have a backbone |
Tell 2 reasons why a backbone is an important part of the vertebrate's body: | 1.supports the animal's body 2. it allows larger and heavier animal to move about |
If your bay temperature does not change much or it is a constant body temperature, what kind of animal are you? | warm blooded |
How do warm blooded animals get heat? | from breaking down food |
If you cannot keep a constant body temperature what are you? | cold blooded |
Where do cold-blooded animals get heat? | from outside their bodies |
How many classes of vertebrates are there? | 7 |
Name the 7 classes of vertebrate? | amphibians, birds, bony fish, fish, jawless fish mammals, reptiles |
Name the three classes of fish? | bony fish, cartilaginous fish, jawless fish |
What are the skeletons of jawless and cartilaginous fish made of? | cartilage |
Name two places that you have cartilage? | tip of my nose & my outer ears |
Describe a jawless fish mouth: | boneless and like a suction cup |
Name a jawless fish: | lampreys |
Name two cartilaginous fish: | sharks and rays |
Name the largest class of vertebrate? | bony fish |
Describe the body of a bony fish: | skeleton is made of bone and it is covered with scales |
Name two bony fish? | goldfish, tuna |
Why might warm blooded vertebrates eat more often than cold blooded vertebrates? | Warm blooded vertebrates maintain a constant body temperature by getting heat from the food they break down. |
How are the 3 classes of fish alike? | live in water & they are cold-blooded |
Name 5 classes of cold-blooded vertebrates? | 3 classes of fish - bony fish, cartilaginous fish, jawless fish amphibians reptiles |
Name two classes of warm-blooded vertebrates: | birds mammals |
Where do amphibians live? | water and land |
Name three amphibians: | frogs, toads, salamanders |
What do frog eggs hatch into? | tadpoles |
How do tadpoles breathe? | gills |
When a tadpole changes what new body part allows it to live on land? | lungs |
How does an adult amphibian breathe? | through its skin |
Why must an amphibian live near water? | to keep its skin moist so it can breathe |
Name the cold blooded vertebrate that lives on land? | reptile |
Describe a reptiles skin so I know why it can live on land? | dry skin, covered in scales that is waterproof |
How do reptiles breathe? | through their lungs |
What is the only animal that has feathers? | birds |
How do feathers help a bird? | keeps it warm and dry |
Can all birds fly? | No |
If a bird cannot fly name 3 traits that are also very helpful? | -light, hollow bones -powerful lungs -strong musles |
How do birds reproduce? | laying eggs |
What do all mammals have? | warm blood fur or hair |
Name two mammals that lay eggs: | duck-bileed platypus & spiny anteater |
Name 3 mammals with pouches: | kangaroo, koalas, opossums |
Name three mammal that have offspring develop inside of them so they give birth? | Humans, sheep, bats, apes, |
life cycle | stages of growth and change |
life span | how long it can live |
metamorphosis | this process has several separate growth stages. Butterflies and other insects go through this process. |
incomplete metamorphosis | growth stages that are hard to see |
complete metamorphosis | each growth stage looks different. Egg, larva, pupa, adult |
clone | an exact copy of its parent |
heredity | the passing of traits |
inherited traits | when traits are passed from parent to offspring |
fertilization | egg and sperm join |
embryo | the fertilized egg |
inherited behavior | a set of actions that parents pass on to their offspring. |
instinct | a way of acting that an animal does not need to learm |
learned behavior | an animal changes its behavior through experience |
reproduce | parents make offspring |
invertebrate | an animal without a backbone |
vertebrae | an animal with a backbone |
sponge | the simplest kind of invertebrate. they do not have symmetry. they live under water cnidarian |
cnidarian | an animal with armlike parts called tentacles. Tentacles are poisonous. jellyfish and coral. |
mollusks | have shells and live in water. invertebrates that live in seashells |
echinoderm | sea urchins. has a spiny skin. |
endoskeleton | the internal support structure in an echinoderms. |
arthropods | the largest invertebrate group. has jointed legs and a body divided into sections. |
exoskeleton | hard body covering that protects the body of and arthropod. |
examples of arthropods | crabs, shrimp, insects and some spiders |
insects | have three pairs of legs, on or two pairs of wings, and three body sections |
arachnids | four pairs of legs,two body sections and fangs........spiders and tincks |
crustaceans | crabs and shrimps, have two pairs of antennae and two to three body sections. the can chew. |
centipedes | one pair of legs on each body section. |
millipedes | two pairs of legs on each body section |
skeletal system | a vertebrate's bones |
muscular system | strong tissues. shorten and pull on the bones |
nervous system | the master control system |
respiratory system | brings oxygen in and removes carbon dioxide |
circulatory system | moves blood through the body |
excretory system | gets rid of wastes |
digestive system | break down food |
