  2. the nuclear membrane
  3. synaptic vessicle membranes
  4. dendrite membranes of the presynaptic cell
College Magnetism and Electricity
What's NOT an electrostatic law?
  1. Repulsion-Attraction
  2. Inverse Square Law
  3. Penetration
  4. Concentration
College Magnetism and Electricity
The greatest of charge will be on the surface where the curvature is sharpest correlates to what electrostatic law?
  1. Concentration
  2. Distribution
  3. Inverse Square Law
  4. Repulsion-Attraction
College Atmosphere
Air near Earth's surface tends to be which of the following?
  1. Warmer and wetter, then it rises, expanding and cooling
  2. Warmer and drier; then it rises, condensing and gathering moisture
  3. Cooler and wetter; then it rises, is warmed by the Sun, and sinks again
  4. Cooler and drier; it rises when it is displaced by sinking warm air
  5. Warmer; it rises as it is displaced by Coriolis forces
College Nervous and Endocrine Systems
Tastes and smells are distinct kinds of environmental information in that                                                                                                      .
  1. distinguishing tastant molecules requires learning, whereas smell discrimination is an innate process
  2. humans can detect many more types of tastants than odorants
  3. odorants are airborne, and tastants are present in fluids
  4. odorants bind to receptor proteins, but none of the tastant stimuli will bind to receptors
College Macromolecules
Select all those that are properties of a protein.
  1. The monomer an amino acid
  2. Among proteins functions are structure, defense, and breakdown of particles.
  3. Proteins act as catalysts.
  4. Amino acids are joined by peptide bonds.
  5. A long chain of amino acids is called a polypeptide.
College Evolution
In a cladogram, the outgroup is the organism that has
  1. the shared derived characters
  2. the shared primitive character
  3. both the shared primitive character and shared derived characters

  1. Nearly all of their cells are in direct contact with the external environment.
  2. Countercurrent exchange mechanisms cannot function well in their living conditions.
  3. They live without the need for oxygen.
  4. They do not produce carbon dioxide.
  5. They are too large for a circulatory system to operate well.
College Acids and Bases
