Diffusion: The movement of molecules from an
area of high concentration to low
concentration in order to reach
equilibrium.
Osmosis:
The diffusion of water; the movement
of water from an area of high
concentration to low concentration in
order to reach equilibrium.

QUESTION 3
Use the information and the diagram below to answer questions 3 and 4.
Starch turns blue-black in the presence of iodine solution. A selectively permeable dialysis sac
containing a starch solution is placed into a beaker of iodine solution.
3. If the dialysis sac is permeable only to water and iodine, what will the solutions in the
beaker and the sac look like after two hours?
a.
The iodine solution in the beaker will turn blue-black; the starch solution will not
change.
b.
The starch solution in the dialysis sac will turn blue-black; the iodine solution will not
change.
c.
Neither solution will turn blue-black.
d.
Both solutions will turn blue-black.
QUESTION 4
Use the information and the diagram below to answer questions 3 and
4.
Starch turns blue-black in the presence of iodine solution. A
selectively permeable dialysis sac containing a starch solution is
placed into a beaker of iodine solution.
Which of these processes is demonstrated by the experiment shown in
the diagram?
a. cellular respiration
b. active transport
c. endocytosis
d. diffusion
QUESTION 5
Many bacteria live in fresh water. Which of these
statements best describes what will happen when
freshwater bacterial cells are placed in salt
water?
a.
b.
c.
d.
Water leaves the cell, causing the cell to
expand.
Water leaves the cell, causing the cell to shrink.
Water enters the cell, causing the cell to
expand.
Water enters the cell, causing the cell to shrink.
QUESTION 6
A student designed an experiment to see if plants grow better when watered with a sugar
solution. He divided the plants into six groups, measured the initial height of each plant,
and calculated the average height for each group. Once a week for two months, he watered
the plants in each group using a different sugar solution for each plant group. At the end
of two months, he measured the final height of each plant and calculated the average
height for each group. The student’s data are shown in the table below.
Which of these statements explains why the plants in Groups E and F died?
a.
The high sugar content caused too much water to move out of the root cells.
b.
The high sugar content caused too much water to move into the root cells.
c.
The high sugar content prevented the plant from capturing energy.
d.
The high sugar content clogged the pores in the cell membranes.

QUESTION 7
The diagram below shows a colony of prokaryotes and a single-celled eukaryote.
The eukaryote contains organelles that resemble the three types of bacteria
found in the colony of prokaryotes. More than a billion years ago, bacteria
like these may have joined other prokaryotes to form colonies of cells.
Researchers think that these once free-living prokaryotes became the
organelles of modern-day eukaryotes.
7. One of the organelles in the eukaryote releases energy from sugars. What is
this process called?
a.
respiration
b.
transpiration
c.
photosynthesis
d.
chemosynthesis
QUESTION 8

QUESTION 10
A group of students measured the volume of air they exhaled during three
different activities: sitting, walking, and running. The volume of exhaled air
is directly related to the amount of carbon dioxide produced. The data the
students collected are summarized in the graph below.
10. Which of these processes produces carbon dioxide?
a.
