Review and Test-Taking Strategies
1. A student designs an experiment that determines the
effectiveness of a particular enzyme. In the design, four types of
food products are used.
The experimenter uses 5ml, 10ml, 15ml, and 20ml of enzyme
with each of the four food types. In addition, the experimenter
places the 5ml and 10ml containers in the freezer. Which of the
following statements BEST describes this experimental design?
A This experimental design will easily be supported by other
scientists.
B This experimental design is flawed due to the lack of a control
variable and the presence of multiple experimental variables.
C This experimental design will produce multiple trials of data.
D This experimental design will show that an enzyme can work
in any temperature and any volume or concentration.

Question
The leaves of plant are dotted with openings
known as stomata. When open, stomata allow
the plant to exchange gases and allow moisture
to evaporate, helping to draw water from the
roots up into the plant. These activities help
the plant to:
A. produce light energy
B. maintain homeostasis
C. decompose organic matter
D. synthesize minerals

C. the cell will burst
D. the cell will shrink and then expand and
then shrink again
Extra Question
In five minutes with at least five lines, answer the following
question below. Turn in after the five minutes. Ensure to write
for the whole time.
Question: Diffusion and osmosis are both vital to cell function.
Describe the similarities and differences between the processes
of diffusion and osmosis.
Similarities: Molecules move from an area of higher
concentration to an area of lower concentration. Neither osmosis
or diffusion require energy and are considered passive transport.
Differences: Diffusion happens when any kind of molecule
moves from any area of higher concentration to any area of lower
concentration, but osmosis refers only to the diffusion of water
across a semi-permeable membrane, such as a cell membrane.
