8. Case
 The body of a man was found floating in
the saltwater Bay, which has a
concentration that is slightly greater than
body fluids. When seen during the autopsy
the cell in his lung tissues were clearly
swollen. Choose the most logical
conclusion
 A. He probably drowned in the bay.
 B. He may have been murdered elsewhere.
 C. He did not drown.

9. Active Transport
 Movement of molecules from an area of
lower concentration to an area of lower
concentration with the aid of carrier
proteins. It requires energy.

11. Endocytosis
The bulk movement of materials
into a cell by the formation of a
vesicle.

12. Pinocytosis
Uptake of small droplets of extracellular
fluid.

13. Receptor-Mediated Endocytosis
A specific receptor protein binds with an
extracellular molecule before digestion.

14. Phagocytosis
Uptake of solid particles.

15. Exocytosis
Movement of material outside the
cell from inside.
