Clemson BIO 1100 Exam 1 - Dr. Minor
Gene Expression - Correct Answer-the process by which information is encoded in DNA
directs the synthesis of proteins or, in some cases RNA's that are no translated into
proteins instead to functional RNA.
form and function - Correct Answer-A big idea in science that asks the learner to
consider the shape of an object and how it relates to what it does. Form changes evolve
over time as functions change.
Element - Correct Answer-A substance that cannot be broken down to other substances
by chemical reactions.
Compound - Correct Answer-a substance consisting of two or more different elements
combined in a fixed ratio. Example: Table Salt (NaCl)
Atom - Correct Answer-the smallest unit of matter that still retains the properties of an
element.
Neutrons - Correct Answer-As the name implies, electrically neutral.
Proton - Correct Answer-one unit of positive charge.
Electron - Correct Answer-one unit of negative charge.
Covalent Bond - Correct Answer-A chemical bond that involves the sharing of a pair of
valence electrons by two atoms.
Molecule - Correct Answer-Two or more atoms held together by covalent bonds.
Single Bond - Correct Answer-a pair of shared electrons.
Double Bond - Correct Answer-a double covalent; the sharing of two pairs of valence
electrons by two atoms.
Valence - Correct Answer-the bonding capacity of a given atom; the number of covalent
bonds that an atom can form, which usually equals the number of unpaired electrons in
its outermost (valence) shell.
Electronegativity - Correct Answer-the attraction of a given atom for the electrons of a
covalent bond.
