Chapter 6-7 Mastering Biology Assignment

A red blood cell is placed into each of the following solutions. Indicate whether crenation, hemolysis, or neither will occur.Solution A: 3.21% (m/v) NaClSolution B: 1.65% (m/v) glucoseSolution C: distilled H2OSolution D: 6.97% (m/v) glucoseSolution E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl Drag each solution to the appropriate bin.

CRENATION: A, D, E HEMOLYSIS: B, C NEITHER:

Two fundamental types of cells are known to exist in nature: prokaryotic cells and eukaryotic cells (like the one shown in the Tour of an Animal Cell animation). Both prokaryotic and eukaryotic cells carry out all of the processes necessary for life, but they differ in some important ways. In this activity, you will identify which cell structures are found only in prokaryotic cells, only in eukaryotic cells, or in both types of cells. Drag each cell structure to the appropriate bin.

PROKARYOTIC ONLY: nucleoid EUKARYOTIC ONLY: nucleous, lyosome, mitochondria BOTH: flagella, plasma membrane, ribosomes

A semipermeable membrane is placed between the following solutions. Which solution will decrease in volume?
