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 Scientific Method
Application of the scientific method involves                                              .
  1. gathering observations
  2. developing a hypothesis based on observations
  3. testing the hypothesis
  4. all of the above
  5. a and b only
College Biology
The following are all considered ultraradian cycles, EXCEPT:
  1. Urinating
  2. Menstrual Cycle
  3. Surfing the Net
  4. Eating
College Lab Practices and Tools
Light microscopes
  1. can generally magnify objects at 10,000 times without blurring.
  2. typically provide higher resolution than an electron microscope.
  3. work by reflecting electrons of the surface of an object being studied.
  4. use light and glass lenses to magnify the image of an object.
  5. are generally not used to view eukaryotic cells.
College Matter
What is matter?
  1. anything that chemists use
  2. a liquid with interesting properties
  3. used as rocket fuel
  4. anything that has a specific volume
  5. anything that has mass and takes up space
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 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
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.
College Taxonomy
Construction of phylogenetic trees (cladograms) is based on the assumption that
  1. new species are formed at a constant and predictable rate
  2. characteristics shared among species reflect descent from a common ancestor
  3. homologous features usually cannot be distinguished from analogous features
  4. most species frequently
College Nervous and Endocrine Systems
A drug that causes potassium to leak out of a neuron, increasing the positive charge on the outside, would                                                          .
  1. cause the cell to release its neurotransmitter
  2. speed up nerve signals traveling the length of the cell
  3. inhibit transmission of nerve signals by the neuron
  4. make it easier to trigger action potentials in the neuron
College Nervous and Endocrine Systems
Action potentials are generated along a neuron because                                                                                                                   .
  1. of cytoplasmic streaming within the neuron
  2. the neuron cytoskeleton conducts electricity as long as an ion gradient is maintained by the sodium-potassium pump
  3. they are pulled along by positive-negative attraction
  4. depolarization of the membrane at one point causes an increase in permeability to sodium at the next point
College Magnetism and Electricity
"Like charges repel and unlike charges attract" relates to what law?
  1. Ohm's Law
  2. Coulomb's Law
  3. Faraday's Law
  4. Newton's Law
College DNA, RNA, and Genetics
Assume that you have crossed orange flowered daisies with white flowered daisies. The offspring of these plants consists of 360 orange flowered daisies and 340 white flowered daisies. What can you conclude about this trait in daises?
  1. The gene for orange flowers is homozygous and the gene fo white flowers is also homozygous
  2. The gene for flower color in daises exhibits incomplete dominance
  3. The gene for orange flowers and the gene for white flowers are on the same chromosome.
  4. The gene for flower color in daisies exhibits complete dominance.
College Waves and Sound
Sound is a transverse, mechanical wave.
  1. True
  2. Flase
College Skin, Skeleton, and Muscles
The body system responsible for providing movement is the
  1. endocrine system.
  2. skin.
  3. musculoskeletal system.
  4. nervous system.
