MULTIPLE CHOICE nb




1. A student is observing a cell under the microscope. It is observed to have
nb nb nb nb nb nb nb nb nb nb nb nb nb




nb supercoiled DNAwith histones. Which of the following would also be observed
nb nb nb nb nb nb nb nb nb nb




by the student?
nb nb nb



a. A single circular chromosome
nb nb nb



b. A nucleus nb




c. Free-floating nuclear material nb nb



d. No organelles nb




ANS: B n b




The cell described is a eukaryotic cell, so it has histones and a supercoiled
nb nb nb nb nb nb nb nb nb nb nb nb nb




nb DNA within itsnucleus; thus, the nucleus should be observed. A single

2. A nurse is instructing the staff about cellular functions. Which cellular
nb nb nb nb nb nb nb nb nb nb




function is the nurse describing when an isolated cell absorbs oxygen and uses
nb nb nb nb nb nb nb nb nb nb nb nb nb




it to transform nutrients to energy?
nb nb nb nb nb nb

, a. Metabolic absorption nb



b. Communication
c. Secretion
d. Respiration

ANS: D n b




The cell’s ability to absorb oxygen is referred to as respiration while its
nb nb nb nb nb nb nb nb nb nb nb nb




communication abilityinvolves maintenance of a steady dynamic state, metabolic
nb nb nb nb nb nb nb nb nb




absorption provides nutrition, and secretion allows for the synthesizing of
nb nb nb nb nb nb nb nb nb nb




new substances.
