5) Algae in the genus Caulerpa typically grow to a length of over half a meter and have
structures similar to stems, leaves, and roots. Reproduction occurs when adults produce sperm
and eggs that fuse to form offspring. Each adult Caulerpa consists of just a single cell, however.
Which of the following statements is TRUE?
A) Caulerpa violate the pattern component of the cell theory that all organisms consist of cells.
B) Caulerpa violate the process component of the cell theory that all cells come from preexisting
cells.
C) Caulerpa violate both the pattern and process components of the cell theory.
D) The existence of Caulerpa is consistent with the cell theory.

6) Cotton-topped tamarins are small primates with tufts of long white hair on their heads. While
studying these creatures, you notice that males with longer hair get more opportunities to mate
and father more offspring. To test the hypothesis that having longer hair is adaptive in these
males, you should ________.
A) test whether other traits in these males are also adaptive
B) look for evidence of hair in ancestors of tamarins
C) determine if hair length is heritable
D) test whether males with shaved heads are still able to mate

,The following experiment is used for the corresponding question(s).
A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two
distinct times of the year: early in spring when the oak trees are flowering and in midsummer
when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look
like oak flowers. But caterpillars that hatch in summer feed on oak leaves and look like oak
twigs.
How does the same population of moths produce such different-looking caterpillars on the same
trees? To answer this question, the biologist caught many female moths from the same
population and collected their eggs. He put at least one egg from each female into eight identical
cups. The eggs hatched, and at least two larvae from each female were maintained in one of the
four temperature and light conditions listed below.
In each of the four environments, one of the caterpillars was fed oak flowers; the other, oak
leaves. Thus, there were a total of eight treatment groups (4 environments × 2 diets).
7) Refer to the accompanying figure. Which one of the following is NOT a plausible hypothesis
to explain the differences in caterpillar appearance observed in this population?
A) The longer day lengths of summer trigger the development of twiglike caterpillars.
B) The cooler temperatures of spring trigger the development of flowerlike caterpillars.
C) Differences in air pressure, due to differences in elevation, trigger the development of
different types of caterpillars.
D) Differences in diet trigger the development of different types of caterpillars.

, 8) Refer to the accompanying figure. In every case, caterpillars that feed on oak flowers looked
like oak flowers. In every case, caterpillars that were raised on oak leaves looked like twigs.
These results support which of the following hypotheses?
A) The longer day lengths of summer trigger the development of twiglike caterpillars.
B) Differences in air pressure, due to elevation, trigger the development of different types of
caterpillars.
C) Differences in diet trigger the development of different types of caterpillars.
D) The differences are genetic. A female will either produce all flowerlike caterpillars or all
twiglike caterpillars.

each of the eight treatments used. This aspect of the experimental design tested which of the

caterpillars.
