Unformatted text preview: filled tubes. (1.5 pts. total) a. Increasing concentration of the test solute. b. Increasing the temperature of the tube and the solute. c. Increasing the molecular mass of the test solute. 6. Define the term osmolarity. (1 pt.) 7. Explain why osmolarity differences are more significant than molarity differences when trying to predict the direction of osmotic water movement. (1.5 pts.) 8. Explain why plant cells are able to live happily in a hypertonic environment while animal cells cannot. (1 pt.) 9. For the exercise where you estimated the osmolarity of some red blood cells, thoroughly explain why the lowest solute concentration at which the cells were unbroken represented a reasonable estimate of the osmolarity of the cells. (2 pts.) 10. Explain the difference between inductive and deductive reasoning. (1 pt.) 11. How does a hypothesis differ from a prediction. [hint – do not refer to a hypothesis as an educated guess.] (1 pt.)...
