Using the forceps, remove the potato core from
Beaker A (blue liquid) and pat it dry with a paper
towel. With the metric ruler, measure the length of the
potato core to the nearest millimeter. Record the
results in the “after submersion” row of Table 1. Then
use the metric balance to determine the mass of the
potato core to the nearest gram. Record the results in
the “after” row of Table 1. Return the potato core to
the sucrose solution in Beaker A.
Repeat these procedures for the potato cores in
Beaker B (red liquid) and the Distilled Water beaker
(clear liquid). Record the results in Tables 2 and 3,
respectively.
Determine the differences between the before and
after measurements in each column, and record your

Bromothymol blue is an indicator that
changes from blue to yellow in the
presence of an acid. When you
exhale through a straw into a test tube
of Bromothymol blue and water, the
water will turn yellow because the
carbon dioxide being exhaled
combines with the water to form a
weak carbonic acid.
H2O + CO2 → H2CO3 (carbonic acid)

viruses replicate through lytic infection. Some viruses
replicate by another method, called lysogenic infection.

next step(s) of the lysogenic cycle?
b. Viruses that replicate using the lysogenic cycle may
not cause any damage to the cell for weeks,
months, or years. Then the virus DNA begins a
process of replication similar to that found in lytic
infection and the virus becomes “active”. Can you

Gene Expression:
All cells contain a set of genes, which can be thought of
as a set of instructions for making each of a very large
number of proteins. The creation of a protein from
its gene is called gene expression. However, for a
given cell not all of these instructions are actually used,
and among those that are, some are used more than
others or only under certain circumstances. Controlling
gene expression is critical to a cell because it allows it to
avoid wasting energy and raw materials in the synthesis
of proteins it does not need. Thus, it allows a cell to be
a more streamlined and versatile entity that can
respond to changing conditions by adjusting its
physiology.
Why don’t cells express all their genes at one time?

TYPES OF MUTATIONS:
Gene/Point Mutations – only affect one gene
Chromosomal: affect whole chromosome
At times, mutations happen during the process of meiosis.
This can lead to significant changes in the offspring of an
organism. Below are some common types of chromosome
mutations. Determine how the genes would be affected in
each situation.

Station 1
Taxonomy
1. Locate the envelope containing the Domain and
Kingdom cards. Make sure you have plenty of space
on your table, then place the domain cards in a row as
shown, with Archaea on the left.
2. Place the kingdom cards beneath the domains to which
they belong. Use the Domain–Kingdom Arrows to
indicate precisely the domain to which each kingdom
belongs.
3. Now, select a Kingdom Characteristics card from the
envelope and place it under the appropriate kingdom
(see below). Continue until all of the cards are correctly
placed. Leave these cards in place.

4. The Kingdom Characteristics cards are shown below
in random order. Referring to your work, write the
name of the kingdom that best fits the characteristics
listed in the space at the top of each column.
5. Locate the Organism cards envelope. Examine the
pictures of the different organisms and discuss their
characteristics with your team. Determine the
kingdom to which each organism belongs and place
each organism picture under the appropriate
kingdom card. (You may need to take up the
Kingdom Characteristics cards to make room.)

organisms. It consists of pairs, or couplets, of
descriptions of organism. By choosing the
description in each pair that matches the
description of an unknown organism, you can
identify the organism.
