2. (B.2C.3) The diagram illustrates what happens to a cell placed in a protein solution. What is the explanation for the process taking place and why?
Before
After
2 hours
* OH
OX
Coll

* Water molecule
Protein molecule
a. Osmosis is occurring because the concentration of water molecules inside the cell increases after
2 hours.
b. Osmosis is occurring because the concentration of water molecules inside the cell is higher at the
beginning and decreases after 2 hours.
c. Active transport is occurring because the concentration of protein molecules is higher in the cell
after hours
d. Active transport is occurring because the concentration of protein molecules inside the cell is
higher at the beginning and decreases after 2 hours
