What is tonicity? Correct Answer the ability of a solution to change shape or tone of cells by altering the cells internal water volume. A solution's tonicity depends on the solution's concentration of nonpenetrating solutes (e.g., NaCl) relative to that in the cell, not on the total osmolarity of the solution. Tonicity provides the information on how the solution affects the cell's volume - Why does it matter if a cell is hypertonic or hypotonic? - Water movement depends on what type of...

Chapter 01: Cellular Biology MULTIPLE CHOICE 1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which of the following would also be observed by the student? 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 nucleus; thus, the nucleus should be observed. A single circular chromosome ca...

Initially there is a high concentration of sodium on the left side of a beaker of water. What is likely to happen (with regard to movement of ions and/or water) in this beaker? - The sodium will move to the right side of the beaker until it is spread out approximately the same throughout the beaker. What is the proper term for the process that is occurring in the beaker on the previous card? - Diffusion A red blood cell is surrounded by a solution containing a higher concentration of solut...
