College Zoology
An invertebrate missing its statoliths would be                                                                                   .
  1. hearing-impaired, but not completely deaf
  2. unable to send action potentials from the ears to the brain
  3. unable to determine which way is up and which way is down
  4. unable to tell the difference between auditory and equilibrium sensory information
College Zoology
In the study of animal behaviors, which pairing of causation with its question is accurate?
  1. proximate- "What stimulus elicits the behavior?"
  2. ultimate - "What physiological mechanisms mediate the response?"
  3. proximate - "How does the behavior aid in survival and reproduction?"
  4. ultimate - "How does the animal's experience during growth and development influence the response?"
College Nervous and Endocrine Systems
While sitting quietly watching television, you suddenly hear the sound of glass breaking. Which is responsible for your resulting rapid heartbeat?
  1. parasympathetic division of the autonomic nervous system
  2. enteric nervous system
  3. central nervous system
  4. sympathetic division of the autonomic nervous system
College Adaptations and Behavior
You look all over for your glasses and then find them pushed back onto your forehead. This experience could be attributed to                        .
  1. a transduction error
  2. sensation amplification
  3. sensory adaptation
  4. perception mapping
College Circulatory and Immune Systems


From the superior vena cava, blood flows to the                   .
  1. right atrium
  2. left atrium
  3. aorta
  4. inferior vena cava
College Nervous and Endocrine Systems
The gray matter of the cerebral cortex, where most higher-level thinking occurs, is composed mostly of                         .
  1. motor neuron cell bodies
  2. glial cells
  3. interneuron cell bodies
  4. axons of sensory cells
College Adaptations and Behavior
Compound eyes are advantageous for small prey species to detect a potential predator because                                                                      .
  1. compound eyes allow animals to detect ultraviolet radiation
  2. with compound eyes, the brain forms many separate visual images
  3. light is not necessary for compound eyes to produce action potentials
  4. they permit sensitive motion detection
College Anatomy and Physiology
A baby is born with the normal number and distribution of rods, but no cones. We would expect that the baby would                                              .
  1. be completely color-blind
  2. have poor night vision
  3. only be able to see colors under bright light
  4. be totally blind
College Nervous and Endocrine Systems
Generally speaking, the intensity of a stimulus (e.g., loudness of a sound, tactile pressure, etc.) is encoded in                                                                            .
  1. the frequency of action potentials transmitted to the CNS
  2. the strength (amplitude) of action potentials transmitted to the CNS
  3. both the frequency and strength of action potentials transmitted to the CNS
  4. the location onto which the sensory information maps in the brain
College Nervous and Endocrine Systems
Which branch of the nervous system includes all of the others?
  1. parasympathetic
  2. motor
  3. sympathetic
  4. autonomic
  5. efferent peripheral
College Nervous and Endocrine Systems
The brain determines the pitch of a sound from the                                                        .
  1. part of the brain receiving nerve impulses from the ear
  2. intensity of nerve impulses received
  3. part of the basilar membrane stimulated by sound
  4. rate of nerve pulses received
College Zoology
Which of the following is an example of a fixed action pattern?
  1. A spider tracks its prey.
  2. A hamster becomes active at the same time each evening.
  3. A stickleback fish attacks a wood block with a red bottom.
  4. A robin eats a noxious bug, spits it out, and never eats a bug that looks like that again.
College Zoology
Which is an example of a circannual rhythm?
  1. Mosquitoes are most active at dawn and dusk.
  2. Just as the sun sets, bats leave their cave in large swarms.
  3. Every spring, cardinals gather in the park to build nests and reproduce.
  4. Fiddler crabs exhibit courtship behavior based on the phase of the moon.
College Nervous and Endocrine Systems
If the following events are arranged in the order in which they occur for an animal hiding and holding still in response to seeing a predator, which is the fourth event in the series?
  1. signaling by an efferent PNS neuron
  2. information processing in the CNS
  3. signaling by an afferent PNS neuron
  4. activation of a sensory receptor
College Zoology
One feature that amphibians and humans have in common is                                                  .
  1. a complete separation of circuits for circulation
  2. the number of heart chambers
  3. a low blood pressure in the systemic circuit
  4. the number of circuits for circulation
