Correct Questions & Answers(RATED
A)
1. Order
2. Evolutionary adaptation
3. Regulation
4. Energy processing
5. Growth & development
6. Response to the environment
7. Reproduction - ANSWERWhat are the 7 characteristics of life?
** If a system is missing one of these, it is not considered living! **
the sum of its parts - ANSWERAs you move to higher levels of biological
organization, each new level is more than just...?
emergent property - ANSWERproperties that would not have been predictable from
merely observing an object/system
reductionism - ANSWERreduction of a complex system to simpler components
which are more manageable for studying
ex) studying DNA helps us to understand inheritance
first shell - 2
second shell - 8
third shell - 8 - ANSWERHow many electrons does it take to fill the first electron
shell? The second? Third?
valence shell - ANSWERan atom's outermost electron shell
ecosystems
communities
organism
tissues
organelles - ANSWERLevels of biological organization, from smallest to largest:
biosphere > __________________ > _____________________ > populations >
_________________ > organs > _______________ > cells > __________________
> molecules

protons - ANSWERAll atoms of an element have the same number of
_______________.
isotopes - ANSWERatoms of the same element that differ in their number of
neutrons (and thus also their mass)
Carbon-12

Carbon-14 - ANSWERWhat are the 3 common isotopes of carbon?
radioactive isotopes - ANSWERisotopes that decay spontaneously, giving off
particles and energy
fossils

diagnosing - ANSWERDating ___________, tracing atoms through
_________________ processes, and ________________ medical disorders are all
applications of radioactive isotopes.
in an atom's outermost electron shell - ANSWERWhere are valence electrons found?
inert - ANSWERElements that have a full valence shell are chemically
______________. (ex: Ne)
The reacting elements' valence shells share electrons so that each can have a full
valence shell - ANSWERWhat happens during a covalent bond?
solid lines - ANSWERHow are covalent bonds depicted?
nonpolar covalent bond - ANSWERbond in which atoms share electrons equally
(due to the bonding elements having approximately equal electronegativity)
polar covalent bond - ANSWERunequal sharing of electrons in a bond (due to
unequal electronegativity)
polar
charges - ANSWERUnequal sharing of electrons in a ___________ covalent bond
causes partial _____________ on the resulting molecule.
