2) How does a scientific theory differ from a scientific hypothesis?
v v v v v v v v v
A) There is no difference—the terms are interchangeable.

B) A theory is an explanation for a very general phenomenon or observation; hypotheses treat

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

preexisting cells.

A) Pasteur demonstrated that it does not occur under normal laboratory conditions.

B) It apparently occurred at least once–when life on Earth began.
v v v v v v v v v

,5) Recall Pasteur's experiment on spontaneous generation. Originally, he used sealed and unsealed
v v v v v v v v v v v
flasks instead of swan-necked and unsealed flasks. Critics claimed that the experiment was
v v v v v v v v v v v v v
inconclusive. Which of the following criticisms would be addressed by using a swan-necked flask
v v v v v v v v v v v v v v
instead of the sealed flask?
v v v v v
A) The broth was heated too intensively.
v v v v v
B) There had not been enough time for spontaneous generation to occur.

v v v v v v v
A) Artificial selection occurs only in computer simulations, not with actual organisms.
v v v v v v v v v v
B) Artificial selection is based on conscious choices by humans.
v v v v v v v v
C) Artificial selection occurs only with plants. v v v v v

necessary and sufficient for natural selection to bring about evolutionary change in a population.
v v v v v v v v v v v v v v
, 8) Over the past several decades, natural selection has caused populations of Staphylococcus aureus
v v v v v v v v v v v v
(an infectious wound bacterium) to evolve resistance to most antibiotics. If antibiotic use were
v v v v v v v v v v v v v v
stopped, what would you predict would happen to these S. aureus populations?
v v v v v v v v v v v v
A) They will go extinct without the antibiotic.
v v v v v v
B) The populations will begin colonizing new environments.
v v v v v v
C) The frequency of nonresistant forms will increase in these populations.
v v v v v v v v v

9) Environments all over the world are changing as a result of global warming. Could this v v v v v v v v v v v v v v
influence natural selection?
v v v
A) No. The environment is always changing. Global warming is nothing new.
v v v v v v v v v v
B) Yes. Traits that help individuals produce more offspring in warmer environments will
v v v v v v v v v v v
increase in frequency.
v v v
C) No. The only change will be that species from hot environments will expand their ranges.
v v v v v v v v v v v v v v

v v v v v v v v v v v v v v v v
that have low amounts of capsaicin over many generations in order to make them milder (have less
v v v v v v v v v v v v v v v v v
