ss following would also be observed bythe student? ss ss ss ss s s s s




a. A s s single circular s s s s chromosome
b. A s s nucleus
c. Free-floating nuclear material ss s s




d. No organelles s s




ANS: s s B
The s s cell s s described s s is s s a s s eukaryotic s s cell, s s so s s it s s has s s histones
s s and s s a supercoiled DNA within itsnucleus; thus, the nucleus should be

ss function is the nurse describing when an isolated cell absorbs s s s s s s s s s s s s s s s s s s




s s oxygen and uses it to transformnutrients to energy? ss r ss ss s s ss ss

,a. Metabolic absorption s s




b. Communication
c. Secretion
d. Respiration

ANS: s s D
The s s cell’s s s ability s s to s s absorb s s oxygen s s is s s referred s s to s s as
s s respiration s s while itscommunication abilityinvolves maintenance of a
