Biology 1201 Final Exam Gregg
UPDATED ACTUAL Questions and
CORRECT Answers
subatomic particles - CORRECT ANSWER - protons, neutrons, electrons
Proton charge and location - CORRECT ANSWER - positive, nucleus
neutron charge and location - CORRECT ANSWER - neutral, nucleus
Electron charge and location - CORRECT ANSWER - negative (-) and outside nucleus in
electron cloud
valence electrons - CORRECT ANSWER - electrons in the outermost shell
incomplete valence shells - CORRECT ANSWER - atoms can share or transfer electrons
with other atoms, or make chemical bonds
Atoms valence - CORRECT ANSWER - Bonding capacity = the number of unpaired
electrons required to complete valence shell
Chemically inert - CORRECT ANSWER - Atoms with a full valence shell, do not form
bonds
Covalent bond - CORRECT ANSWER - the sharing of a pair of valence electrons by two
atoms
Electronegativity - CORRECT ANSWER - A measure of the ability of an atom in a
chemical compound to attract electrons
,nonpolar covalent bond - CORRECT ANSWER - Share e- equally
polar covalent bond - CORRECT ANSWER - unequal sharing of electrons
The # of unpaired e- in the valence shell of an atom = - CORRECT ANSWER - Valence or
# of covalent bonds it can form
Properties of water - CORRECT ANSWER - cohesive behavior, ability to moderate
temperature, expansion upon freezing, versatility as a solvent
cohesion of water molecules - CORRECT ANSWER - hydrogen bonds hold water
molecules together, helps the transport of water against gravity in plants
moderation of temperature by water - CORRECT ANSWER - Water absorbs heat from
warmer air and releases stored heat to cooler air
Water can absorb or release a large amount of heat with only a slight change in its own
temperature
Versatility as a Solvent (Water) - CORRECT ANSWER - The property of water that allows
it to dissolve polar substancess
Solute - CORRECT ANSWER - what is being dissolved
aqeuous solution - CORRECT ANSWER - a solution in which the solvent is waters
Solution - CORRECT ANSWER - A homogeneous mixture of two or more substances
Solvent - CORRECT ANSWER - A liquid substance capable of dissolving other
substances
, Expansion upon freezing of water - CORRECT ANSWER - Hydrogen bonds make ice less
dense than liquid water. The lattice structure of ice makes it less dense than the freely flowing
molecules of liquid water, enabling it to float on water
Hydration Shell - CORRECT ANSWER - the sphere of water molecules around a
dissolved ion
High specific heat of water allows - CORRECT ANSWER - Minimal temperature
fluctuations to within limits that permit life
Heat - CORRECT ANSWER - thermal energy in transfer from one body of matter to
another
kinetic energy - CORRECT ANSWER - energy of motion
potential energy - CORRECT ANSWER - stored energy that results from the position or
shape of an object
Hydrophilic - CORRECT ANSWER - Affinity to water
Hydrophobic - CORRECT ANSWER - Water fearing
if ice sank what would happen? - CORRECT ANSWER - all bodies of water would
eventually freeze solid, making life impossible on Earth
water's high specific heat - CORRECT ANSWER - Hydrogen Bonding
Heat absorbed - CORRECT ANSWER - hydrogen bonds break
