College Environmental Science
Which of the following are indicators of an improving quality life for humans?
  1. air and water quality is improving
  2. food supply is getting more abundant and safer
  3. Grasslands and wetlands are being restored
  4. decreased infant mortality
  5. All of the above
College Small Bodies and Dwarf Planets
Imagine a new object is discovered in the solar system. It is orbiting the Sun at a distance of 2.8 AU. The object is known to be of sufficient mass to be spherical in shape. Would this object be classified as a planet or a dwarf planet?
  1. Planet, it meets all three criteria necessary to be classified as a planet
  2. Planet, any object that is spherical and is in orbit around the Sun is a planet.
  3. Dwarf Planet, it meets the first two criteria for a planet, but it orbits in the asteroid belt, so it does not meet the third criteria.
  4. Dwarf Planet, it meets the first two criteria for a planet, but it orbits in the Kuiper Belt, so it does not meet the third criteria.
College Atmosphere
The Coriolis effect
  1. keeps Earth from spinning too fast.
  2. is caused by the Moon.
  3. results in ice and dark at the poles in winter.
  4. keeps the wind circulating at constant speed around the planet.
  5. is caused by Earth's rotational forces.
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 Nervous and Endocrine Systems
College Biology
The following are all considered ultraradian cycles, EXCEPT:
  1. Urinating
  2. Menstrual Cycle
  3. Surfing the Net
  4. Eating
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 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 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 Nervous and Endocrine Systems
College Environmental Science
Carbon dioxide is
  1. the most potent (per molecule of gas) of the greenhouse gases.
  2. the most abundant greenhouse gas.
  3. more potent (per molecule of gas) than methane.
  4. the main anthropogenic greenhouse gas produced in the United States.
  5. the only greenhouse gas presently increasing in the atmosphere.
