Multiple Choice
1. A Student Is Observing A Cell Under The Microscope. The Student Notices It To Have Supercoiled Dn
Would The Student Be Expected To Observe?
a. A Single Circular Chromosome
b. A Nucleus
c. Free-Floating Nuclear Material
d. No Organelles
Ans: B
The Cell Described Is A Eukaryotic Cell, So It Has Histones And A Supercoiled Dna Within Its Nucleu
Be Observed. A Prokaryotic Cell Contains A Single Circular Chromosome And Lacks Organelles.
2. A Nurse Is Instructing The Staff About Cellular Functions. Which Cellular Function Is The Nurse Desc
Isolated Cell Absorbs Oxygen And Uses It To Transform Nutrients To Energy?
a. Metabolic Absorption
b. Communication
c. Secretion
d. Respiration
Ans: D
The Cell’s Ability To Produce Energy Is Respiration. Communication Involves Maintenance Of A Stea
Metabolic Absorption Provides Cellular Nutrition, And Secretion Allows For The Delivery Or Release
