  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
Circulatory systems compensate for what?
  1. The problem of communication between the nervous system and respiratory system.
  2. The slow rate at which diffusion occurs over large distances.
  3. Temperature differences between the lungs and the active tissue.
  4. The need endothermic organisms have for maintaining an optimal body temperature.
College Zoology
Which of the following statements regarding the adult mammalian heart is correct?
  1. When the right atrium contracts, it forces blood into the left atrium.
  2. Blood in the right chambers of the heart cannot enter the left chambers without passing through the lungs.
  3. Blood is pumped from the heart via the atria.
  4. Blood arrives at the heart via the ventricles.
College Zoology
Air-breathing insects carry out gas exchange                                                              .
  1. in their specialized internal gills.
  2. across all parts of their thin exoskeleton.
  3. across the finest branches of the trachea and cell membranes.
  4. in the alveoli of their lungs.
College Nervous and Endocrine Systems
The                 branch of the nervous system receives sensory information and controls muscle movements.
  1. central
  2. sensory-motor
  3. vagal
  4. somatic
  5. autonomic
College Zoology
In the example from the textbook reading, male prairie voles are monogamous. They are attentive to young, and aggressive toward intruders. This appears to be related to                                                                           .
  1. special chemicals in female vole urine that promote such behavior in males
  2. the prevalence of monogamy among rodent species
  3. the heavy investment most male mammals place in parental care
  4. the distribution of neuropeptide receptors in the brains of voles
College Zoology
Which of the following could be considered the most recent common ancestor of living tetrapods?
  1. a sturdy-finned, shallow-water lobe-fin whose appendages had skeletal supports similar to those of terrestrial vertebrates
  2. an armored gnathostome with two pairs of appendages
  3. an early ray-finned fish that developed bony skeletal supports in its paired fins
  4. a salamander that had legs supported by a bony skeleton but moved with the side-to-side bending typical of fish
College Taxonomy
Most bilaterians have a coelom (fluid- or air-filled body cavity), which is important for all of the following, EXCEPT                                                                                  .
  1. cushioning organs
  2. acting as a hydrostatic skeleton
  3. allowing for independent movement of internal organs
  4. enabling the concentration of sensory equipment at the anterior end of the animal
College Biology

  1. Urinating
  2. Menstrual Cycle
  3. Surfing the Net
  4. Eating
College Anatomy and Physiology
The "all-or-none" law refers to the observation that an action potential
  1. will diminish to near zero when transmitted down a long axon.
  2. is conducted more rapidly down the axon as it reaches the axon terminal.
  3. is produced whenever the membrane potential reaches threshold.
  4. fires at the same rate regardless of the inputs to the neuron.
  5. travels only in one direction.
College Nervous and Endocrine Systems
How are neurons structurally adapted to chemically transmit impulses to neighboring neurons?
  1. They have Schwann cells that surround axons.
  2. They have numerous nodes of Ranvier.
  3. They have numerous dendrites.
  4. Axon terminals contain neurotransmitter with synaptic vessicles.
College Nervous and Endocrine Systems
The part of the lymphatic system that is also part of the endocrine system is the
  1. spleen.
  2. thymus.
  3. lymph nodes.
  4. tonsils.
