which vertebrate has a heart with four chambers?

cow

aquatic animals that strain floating plants and animals from the water they take in are

filter feeders

vertebrae are a characteristic of

vertebrates only

what invertebrates exchange gases through their gills?

Clams

which reptile would be most likely to excrete nitrogenous wastes in the form of uric acid

a desert tortoise

The Fischer's lovebird build its nest with long strips of vegetation that it cuts with its beak. A closely related species, the peach-faced lovebird, cuts shorter strips for its nest. When these two species are interbred, the hybrid offspring cut strips of intermediate length for their nests. These observations suggest that this aspect of nesting building is

an innate behavior

a vertebrate is any chordate that has a

backbone

unlike plant cells, animal cells do not have

cell walls

migration is a behavior that is usually influenced by

changing seasons

Filter feeders include all the following EXCEPT

crocodiles

Which body system includes the rumen?

digestive (system)

Suppose a terrestrial vertebrate has an optimal body temp. of 37 degrees C but lives in an environment where the air temp. is 40 degrees C. which of the following is the most important requirement for that vertebrate to control its body temp.?

eliminate excess body heat

which of the following help mammals retain body heat?

hair and body fat

Raccoons are omnivores, which means that they eat both meat and plant material. If you compared the digestive tract of the raccoon with that of a similar sized herbivore and a similar sized carnivore, the raccoon's digestive tract would most likely

have a length intermediate between the herbivore and the carnivore

if a butterfly touches sugar water with one of its legs, it usually will begin to feed, If it touches salt water, it usually will not feed. The most likely explanation for this different in response is that butterflies

have chemical receptors for taste on their legs

People who move into an apartment near railroad tracks are awakened at night each time they hear a train go by. After about a week, they can sleep through the night, even though the trains continue to run on the same schedule. The change in their sleeping behavior is an example of

hibituation

most reptiles exchange gases through their

lungs

if a species of fish reproduces through external fertilization, that species must be

oviparous

when disturbed, certain moths lift their front wings to expose eye like markings on their hind wings. This behavior would be most effective against predators that hunt by

sight

Most flatworms are small and very thin. Therefore, they can supply their cells with oxygen and remove metabolic wastes by means of

simple diffusion between body surface and the environment

the main difference between ectotherms and endotherms is

the source of their body heat
