Detritivores feed on
decaying plant and animal material.
plants
animals
insects
An animal that relies primarily on intracellular digestion is the

Parasitic symbionts
Mutualistic symbionts
Occupants that have no effect on the coral animals
Consumed as food by the coral animals
Most terrestrial insects breath using a network of structures called
gills
tracheal tubes
gill tubes
book lungs
In order for the exchange of oxygen and carbon dioxide to take place, an animals respiratory surfaces must be kept
cold
dry
hot
moist
Most fishes exchange gases by pumping water from their mouths
Over their gills
Through the lungs
Over their atria
Through their esophagus
Most reptiles excrete wastes in the form of
urea
ammonia
uric acid
toxins
Freshwater fish
excrete excess water through their kidneys.
lose water through osmosis.
conserve water by producing concentrated urine.
pump excess salt out across their gills.
Some terrestrial invertebrates produce urine in the
kidneys
gills
nephridia or Malpighian tubules.
nephrostomes.
What adaptation have some marine reptiles and birds evolved to eliminate excess salt?
They have specialized kidneys that can store the salt safely.
They excrete urine that is 25 percent more concentrated than their blood.
They have specialized glands in their heads that excrete solutions.
They pump out the excess salt across specialized gills.
How do kidneys remove excess water from the blood?
The kidneys use active transport to remove water from the blood.
Kidneys use passive diffusion to remove water from the blood.
Kidneys use passive osmosis to remove water from the blood.
Kidneys use their nephridia to filter water out of the blood.
Aquatic reptiles and mammals exchange gases using
gills
skin
lungs
mantle cavities
Examining the teeth of an animal can give information about whether it
Practices intracellular or extracellular digestion
is a filter feeder or a detritivores
is a nutritional symbiont
is a herbivore or a carnivore
In an open circulatory system, blood
is confined to blood vessels at all times
circulates around body tissues
exchanges gases with lung alveoli
is not required for exchanging gases with body cells
In chordates with four-chambered hearts, there is
only one loop in the circulatory system
mixing of oxygen-rich and oxygen-poor blood
partial partition of the ventricle
no mixing of oxygen-rich and oxygen-poor blood
The elimination of metabolic wastes from the body is called
excretion
circulation
respiration
digestion
The composition of and levels of body fluids in mammals are controlled by the
lungs
kidneys
intestines
heart
Most arthropods have
no circulatory system
an open circulatory system
a closed circulatory system
skin gills
A side-to-side movement of the jaws would be most useful in an animal that eats
blood
meat
algae
grass
Which of the following groups of animals has the most efficient gas exchange?
amphibians
reptiles
birds
mammals
Information in the environment that causes an animal to react is
a control
an interneuron
a response
a stimulus
Which of the following invertebrates has cerebral ganglia that are organized into a brain?
sea star
earthworm
coral
octopus
Humans have lungs with alveoli. This implies that humans
have a lower metabolic rate than amphibians and reptiles.
have a higher metabolic rate than amphibians and reptiles.
have the same metabolic rate as amphibians.
have the same metabolic rate as reptiles.
A closed circulatory system is one in which
blood spreads freely throughout the body’s tissues.
blood travels through a system of blood vessels that extend throughout the body.
blood travels through blood vessels into spongy cavities called sinuses.
blood travels through a system of blood vessels and air sacs.
Which of the following animals has a two-chambered heart?
garter snake
dog
African bullfrog
trout
Kidneys that can conserve water are essential to homeostasis because
some animals live in dry or salty environments.
some animals drink water.
urea is not soluble in water.
their cells will be unable to convert ammonia into urea if excess water is excreted.
A gastrovascular cavity is
the interior of a mammal’s digestive system.
the body space in some invertebrates where digestive and circulatory functions occur
the part of a bird’s digestive tract that breaks food into small pieces.
the opening in a one-way digestive tract from which wastes are expelled.
A collection of neurons connected in a netlike arrangement with few specializations is called a
nerve cord.
cerebellum.
nerve net.
ganglia
When an animal responds to a stimulus, what body systems work together to generate a response?
the sensory neurons, nervous system, and muscles
the cerebellum, cerebral ganglia, and cerebrum
the neurons, interneurons, and nerve nets
the neurons, nerve nets, and sensory neurons
Nervous systems are composed of specialized nerve cells called
interneurons
neurons
cerebral ganglia
sensory neurons
Highly developed nervous systems contain many
sensory neurons
motor neurons
interneurons
nerve nets
A lobster is an example of an animal that has a(n)
hydrostatic skeleton
exoskeleton
endoskeleton
limb girdle
The places where parts of a skeleton are connected together to enable movement are called
joints
ligaments
tendons
muscle blocks
What is the process that allows arthropods to increase in size?
molting
shedding
splitting
breaking
What type of skeleton do echinoderms and vertebrates have?
hydrostatic skeleton
exoskeleton
endoskeleton
limb girdle
The tissues that connects bones to muscles is called
ligaments
tendons
connective tissues
cartilage
Carnivores have teeth that are designed to
grind
slice
rasp
pull
The part of the vertebrate nervous system that connects the brain and the rest of the body is called the
spinal cord
vertebral column
cerebral ganglia
medulla oblongata
Which of the following groups of animals rely on sensory cells rather than sensory tissues and organs?
cephalopods
fishes
mammals
tunicates
What does molting enable arthropods to do?
to breathe
to reproduce
to grow
to eat
Joints are a critical feature of both endoskeletons and exoskeletons because
jointed skeletons are more lightweight than rigid skeletons.
joints provide flexibility and freedom of movement.
joints allow an animal to change its body shape.
joints are necessary for molting to occur.
Study Figure 28–1. Which of the letters represents an interneuron?
A
B
C
D
The compound eyes of insects
detect color and form images.
are located on the thorax.
produce an image that is more detailed than what humans see.
are not very good at detecting movement.
Which of the following characteristics is associated only with an endoskeleton?
It offers protection from predators.
It allows an animal to walk.
It must be molted in order for the animal to grow.
It grows with the animal.
