BYU Bio 130 Exam 1 Johnson and
Adams Questions & Answers
Chemical Bonds Correct Ans-Forces that hold atoms together in a molecule
Covalent Bond Correct Ans-Chemical bond in which electrons are shared
Ionic Bond Correct Ans-Chemical bond between ions, one or more electrons have been
transferred
Hydrogen Bond Correct Ans-Chemical bond in which a hydrogen is shared between two
electronegative atoms (usually O and/or N)
Solute Correct Ans-A molecule dissolved in a liquid
Solvent Correct Ans-The liquid in which the molecule is dissolved
Theory Correct Ans-An explanation using an integrated set of principles that organizes
observations and predicts behaviors or events.
Fact Correct Ans-A piece of information provided objectively, presented as true.
,Hypothesis Correct Ans-A proposed, scientifically testable explanation for an observed
phenomenon.
Theory of Evolution Correct Ans-The best scientific explanation for both the unity and
diversity of life; proposed by Charles Darwin
Phylogenetics Correct Ans-The analysis of evolutionary, or ancestral, relationships between
taxa
Natural Selection Correct Ans-A process in which individuals that have certain inherited
traits tend to survive and reproduce at higher rates than other individuals because of those
traits.
Positive Control Correct Ans-Group expected to have a positive result, allowing the
researcher to show that the experimental set up was capable of producing results.
Potential Energy Correct Ans-Energy stored due to an object's position or arrangement
Valence Electrons Correct Ans-The electrons in the outermost shell (main energy level) of an
atom; these are the electrons involved in forming bonds.
Octet Rule Correct Ans-States that atoms lose, gain or share electrons in order to acquire a
full set of eight valence electrons
, Molecule Correct Ans-A group of atoms bonded together
Polar Correct Ans-Molecule with partial charges. Mixes with water.
Non Polar Correct Ans-Equal sharing of electrons. No partial charges.
Specific Heat Correct Ans-The amount of energy required to raise the temperature of 1 gram
of a substance by 1 degree celcius
Hydrophobic Correct Ans-Having an aversion to water; tending to coalesce and form droplets
in water.
Hydrophilic Correct Ans-having a tendency to mix with, dissolve in, or be wetted by water.
Amphipathic Correct Ans-Molecules are said to be this when it has regions that are both
hydrophilic and hydrophobic.
Polymer Correct Ans-A long molecule consisting of many similar or identical monomers
linked together.
Monomer Correct Ans-The subunit that serves as the building block of a polymer.
