Exam 7 Study Guide

The process of transformation from an immature form to an adult form in two or more distinct stages

Different phases of life that all individuals that metamorphosize will pass through in the development stage of their lifetime

An organism that cannot change their body temperature to support them in extreme environments/temperatures

Organism that is able to maintain an internal body temperature, generally will have fur or hair

Can breathe through skin, cold blooded, in the phylum Chordata, lives in wet environments, has egg larvae adult life cycles

Air breathing, scales, no eye lids - crocodiles, snakes, lizards, turtles, tortoises

Feathered vertebrates with toothless-beaked-jaws; they have parental care, nest building, courtship, and territorial behavior

Class that characterizes birds, Scientific Latin word for Bird

Animals who have a backbone, same things as "chordate"

Both sides of an organism will look relatively the same if you draw a line down the middle

Blood is enclosed in blood vessels

The body system that deals with the breaking down of food and the release of molecules and proteins inside of it

Only phylum with backbone includes fish, birds, reptiles, amphibians, and mammals

Life cycle stage in between egg and adulthood

Reptiles removing old skin to reveal new skin

Turnover time in which food is transformed into energy

Skin of a reptile, hard surface

Skin of a reptile, small plates that are more flexible

1. Needs water, moist environments 2. Breathes through skin 3. Special skin glands that produce useful proteins 4. Some are toxic 5. Egg larvae adult life cycle 6. Cold blooded

1. Respiration through nostril and mouth (not skin) - Air breathing 2. Shed skin; skin has scales, bony plates, or both 3. Metabolism depends on temperature 4. Cold blooded 5. Reproduction depends on temperature

1. Feathers 2. Toothless beaks 3. Hard shell eggs 4. High metabolism 5. Four-chambered heart (like mammals & humans) 6. Strong, light skeleton

Too much sun, too much wind (reason ¼ frog species are near extinction)

Female lays eggs, male watches egg, larvae develops and parental care ends. Metamorphosis continues to adulthood in the water. Once a full adult, amphibian will crawl on land & in-water

Similarities: camouflage, play dead, amphibians; Frogs: smooth slimy skin, long tongue, 95% life in water, white belly; Toads: bumpy skin, short tongue, 10% life in water, camo colored belly

Too hot & too cold → baby boy; Consistent middle temperature → baby girl; Eggs laid in nests; Boas & Pythons have "live young"

Males will show off looks and skills in order to lure a female

Adult bird tends to and takes care of growing young & raising young until it can fly on its own—then parental care is over

Birds build their nest to live in, gathering materials like twigs, water, mud, hay, dirt, to combine to build their nest

Animal is very concerned about a specific area; this is a sign of ownership. Bird will defend territory by pecking & making noise & expand wings & puff up body

Amphibians: Need water/moist environments, Breathe through skin, Have egg-larvae-adult lifecycle; Cold blooded

Reptiles: Air breathing (nostril/mouth), Have scales and bony plates, Cold blooded, Temperature-dependent metabolism

Birds: Have feathers, Toothless beaks, Hard shell eggs, High metabolism, Four-chambered heart​​​​​​​​​​​​​​​​
