Biology 101 Chapters 1-5 ExamQuestions with Complete Solutions
hypothesis - Answer-the procedure for an experiment is the test of the:
treatment - Answer-which group gets the treatment in an experiment?
control - Answer-which group does not include the treatment and can be used for
comparison?
conclusion - Answer-which of the following either accepts or rejects the hypothesis?
control - Answer-which group is identical to the treatment group but does not include the
treatment?
proton - Answer-the positive charge in the nucleus
electron - Answer-the negative charge in an atom
isotope - Answer-same number of protons but different number of neutrons
ion - Answer-an atom with a charge
energy level - Answer-an uneven number of protons and electrons in an atom creates:
stable octect - Answer-what describes when there are 8 electrons in the outermost
energy level of an atom giving the atoms greater stability and causes reactions to
occur?
covalent - Answer-what type of bonds are formed when atoms share valence electrons
to reach the stable octet and gain the accompanying greater level of stability?
no charge - Answer-what does it mean when 2 or more molecules are neutral?
nonpolar molecule - Answer-what results from an equal sharing of electrons?
hydrogen - Answer-which are weak bonds that occur between the H+ of 1 atom, and
either a O- or a N- of another atom?
hydrogen - Answer-what type of bond is largely responsible for the surface tension in
water?
radioactive isotopes - Answer-which is not a common characteristic of water?
, sugar - Answer-if a glass contains sugar and water, which is the solute?
hydrophilic - Answer-which type of substances dissolve in water
acids - Answer-what are the solutions where there are more H+ present than OH?
base - Answer-if a solution has a pH greater than 7 it is a
buffer - Answer-what type of solution tends to maintain a constant pH whenever an acid
or base is added?
functional group - Answer-what are reactive "add-ons" that are attached to carbon
chains to fulfill a biological function
dehydration - Answer-what type of reaction removes a water molecule in the process of
joining 2 or more monomers?
hydrolysis - Answer-what type of reactions add a water molecule to decompose
polymers back into their monomer subunits?
hydrolysis - Answer-Which type of reaction is the opposite of dehydration?
carbohydrate - Answer-in what type of biomolecule is the ratio of C:H:O is always 1:2:1?
carbohydrate - Answer-monosaccharides are a type of
monosaccharide - Answer-C6 H12 O6 is the simplest and most common
polysaccharide - Answer-which are 2 or more monosaccharides bonded together via
dehydration synthesis?
amino acids - Answer-what combines via dehydration synthesis to make proteins?
amino acids - Answer-which contains 3 functional groups: an amino group (-NH2), a
carboxylic acid group (-COOH), and an R group?
peptide - Answer-What type of bond joins 2 amino acids forming a peptide?
secondary - Answer-which structure occurs when hydrogen bonds twist the primary
structure into a helix or a pleated sheet?
intrinsically disordered - Answer-what type of proteins are flexible allowing them to fold
in various ways which enables them to interact with different molecules rather than just
a single molecule?
