Qualifications of Life -ANSWER (1) Order/complex organization, (2) Response to
environment, (3) Reproduction, (4) Evolution, (5) Growth, (6) Internal regulation, (7)
Homeostasis, and (8) Energy processing
The 5 Kingdoms -ANSWER Monera, Protoctista, Fungi, Plantea, and Animalia
The 3 Domains -ANSWER Bacteria, Archaea, Eukarya
Smallest to largest levels of organization -ANSWER Atom, molecule, organelle, cell,
tissue, organ, organ system, organism, population, community, ecosystem, biosphere
Science -ANSWER -Field of study that seeks natural explanations for natural
phenomena.
-Must be observable, measurable, and variable
Discovery Science -ANSWER Science describing nature
Hypothesis-based Science -ANSWER Science that involves the scientific method
The Scientific Method (Steps) -ANSWER (1) Observation, (2) Question, (3) Hypothesis,
(4) Prediction, (5) Testing
Matter -ANSWER Anything that has mass and takes up space
Element -ANSWER A substance that cannot be broken down into simpler substances
Essential Elements of Life -ANSWER Carbon, hydrogen, oxygen, nitrogen
Atom -ANSWER Smallest particle of an element
Atomic Number -ANSWER The number of protons in the nucleus of an atom. Defines the
element.
Atomic Mass -ANSWER The number of protons and neutrons combined
Electrons Shells -ANSWER -Where the electrons reside.
-Can hold 2 or 8 electrons
, Inert vs. Reactive -ANSWER Inert atoms have a full outer shell while reactive atoms have
an outer shell that is incomplete and ready to form bonds.
Chemical Bond -ANSWER Interaction between 2 or more atoms that result in each atoms
having a full outer shell. Electrons may be donated, received, or shared.
Ionic Bond -ANSWER Bond between oppositely charged atoms called ions
Ion -ANSWER An atom that has gained or lost electrons, thus acquiring a charge.
Covalent Bond -ANSWER Involves sharing an electron to stabilize 2 atoms
Molecule -ANSWER Two or more atoms held together by covalent bonds
Electronegativity -ANSWER The strength of an atom's attraction for electrons
Low of High EN?:
Carbon and Hydrogen -ANSWER Low EN
Low or High EN?:
Oxygen and Nitrogen -ANSWER High EN
Hydrogen Bond -ANSWER Weak attraction between a slightly positive hydrogen atom
and a slightly negative atom. Holds water together
Polar Covalent Bond -ANSWER A covalent bond in which electrons are not shared
equally between atoms
Polar -ANSWER Describes a molecule with opposite charges on opposite ends
Trace Elements -ANSWER Elements required by an organism in only small quantities.
Solute -ANSWER The substance that is dissolved
Solvent -ANSWER The substance in which the solute dissolves
Unique properties of water -ANSWER (1) Cohesive, (2) Able to resist temperature
change, (3) Becomes less dense when frozen, and (4) A great solvent
Chemical Reaction -ANSWER Bonds are broken and formed to initiate a change in the
composition of molecules
Why is carbon important? -ANSWER -It is present in all living things
-Nature's most versatile atom
-Can make 4 bonds because it has 4 outer electrons
