2. Where r is r most r of r a r cell’s r genetic r information, r including r RNA r and r DNA, r contained?
a. Mitochondria
b. Ribosome
c. Nucleolus
d. Lysosome
ANS: r C
The r nucleus r contains r the r nucleolus, r a r small r dense r structure r composed r largely
r of r RNA,rmostof r the r cellular r DNA, r and r the r DNA-binding r proteins, r such r as r the
r histones, r which rregulate rits ractivity. r The rmitochondria rare r responsible r for

a. Lysosomes
b. Peroxisomes

rremove rhydrogen ratoms rfrom rspecific rsubstrates rin ran roxidative rreaction r that
r produces rH2O2, r which r isa r powerful r oxidant r and r potentially r destructive r if r it

rLysosomes rare rsaclike rstructures rthat r originaterfrom r the r Golgi r complex r and r contain
r more r than r 40 r digestive r enzymes r called r hydrolases, rwhich r catalyze r bonds r in
r proteins, r lipids, r nucleic r acids, r and r carbohydrates. r An r endosome ris r a r vesical r that

c. Increased r retention r of r water
d. Breakdown r of r fat
ANS: r C
Antidiuretic r hormone r leads r to r increased r retention r of r water r in r the r body.
r Epinephrine rcauses r increases r in r heart r rate r and r force r of r contraction. r Increased
