MULTIPLE CHOICE u




1. A student is observing a cell under
u u u u u u u the microscope. It is observed
u u u u




u to have supercoiled DNAwith histones. Which of the following
u u u u u u u u




u would alsobe observed by the student?
u u u u u u



a. A single circular chromosome
u u u



b. A nucleus u



c. Free-floating nuclear material u u



d. No organelles u




ANS: B
The cell described is a eukaryotic cell, so it has histones and a
u u u u u u u uuu uuu uuu uuu u




u supercoiled DNA within itsnucleus; thus, the nucleus should be
u u u u u u u u




u observed.A single circular chromosome called a prokaryote contains free-
u u u u u u u u u




floating nuclear material but has no organelles.

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




u function is the nurse describing when an isolated cell absorbs oxygen
u u u u u u u u u u




u anduses it to transform nutrients to energy?
u u u u u u u

, a. Metabolic absorption u



b. Communication
c. Secretion
d. Respiration

ANS: D
The cell’s ability to absorb oxygen is referred to as respiration while
u u u u u u u u u u u




u itscommunication abilityinvolves maintenance of a steady dynamic state,
u u u u u u u u




u metabolic absorption provides nutrition, and secretion allows for the
u u u u u u u u




u synthesizing of new substances.
