Semester Two Day Two Science Exam Review Flashcards
What do all annelids have in common. Give two examples
They all have long round bodies with segments
Leeches, earthworms
What do all mollusks have in common
They all have a mantle, a foot, and visceral mass
Three types of mollusks and an example of each
Gastropoda-snail
Bivalvia-clam
Cephalopoda-squid
What do all Arthropoda have in common
Jointed legs, exoskeleton, and distinct body segments
Four types of Arthropoda and an example for each
Myriapoda-centipede
Insect-lady bug
Crustacean-crab
Arachnid-spider
Exoskeleton vs endoskeleton
Exoskeleton-body support and protection on outside of body(armor)
Endoskeleton-body support and protection on inside of body(frame of house)
What does echinodermata mean
Spiny skin
What do all echinodermata have in common. Give two examples
They all have tube feet, water vascular system, and radial nerves
Sea urchin and sea star
Endothermic vs ectotherm
Endotherm- gets heat for bodies from the chemical reactions that occur in the body
Ectotherm-get heat from environment
Four body parts all vertebrates have at some point in their lives
Tail
Notochord
Hollow nerve cord
Pharyngeal pouches
How do gills work
Fish take water in through mouth. It goes over gill membrane. The gill membranes take oxygen out of the water and deliver it to the blood
What do all fish have in common
Gills, lateral line, live in water
Three types of fish and examples for each
Jawless fishes-hagfish
Cartilaginous fishes-sharks
Bony fishes-perch
How do bony fish use swim bladder
Swim bladder fills with air to allow fish to float in the water at a certain level without moving
Why do amphibians need to live near water
Lay eggs, develop in early stages, keep their skin moist, drink through skin
How are amphibians ecological indicators
They are sensitive to changes in water or on land cause they live in both for most of their lives. Their skin easily absorbs chemicals in both water and air
Reptile eggs vs amphibian eggs
Amphibian eggs-no shell or amniotic fluid, so must stay in water
Reptile eggs- shell and amniotic fluid so they won’t dry out on air
Two ways reptile skin is different from amphibian skin
Thick skin
Dry
Down feathers vs contour feathers
Down feathers-lie next to body, help Bird stay warm
Contour feathers-stiff feathers that cover body and wings, give color and shape, flight feathers
Five reason why birds can fly and humans can’t
Rapid heart beat Keel Flight muscles Hollow bones Air sac to provide constant oxygen
Precocial vs altricial
Precocial-born active, eyes open, fluffy feathers, swim, walk
Altricial- no feathers eyes closed, practically helpless
Four types of birds and example of each
Flightless bird-penguin
Water bird-wood duck
Perching Bird-chickadee
Raptor-osprey
List five mammal groups and give an example for each
Carnivores-lion Trunk-nosed mammals- elephant Hoofed mammals- horse Primates-monkey Cetacean-dolphin
Distinguishing characteristic of monotremes and an example
Lays eggs
Platypus
