2) How does a scientific theory differ from a scientific hypothesis?
A) There is no difference—the terms are interchangeable.
U
B) A theory is an explanation for a very general phenomenon or observation; hypotheses
treatmore specific observations.
C) A hypothesis is an explanation for a very general phenomenon; theories treat more
R
specificissues.

3) Algae in the genus Caulerpa typically grow to a length of over half a meter and have
TE
structures similar to stems, leaves, and roots. Reproduction occurs when adults produce sperm
and eggs that fuse to form offspring. Each adult Caulerpa, however, consists of just a single cell.
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.

4) Which statement about spontaneous generation is FALSE?
A) Pasteur demonstrated that it does not occur under normal laboratory conditions.
B) It apparently occurred at least once–when life on Earth began.
C) It occurs every time a new species evolves from a preexisting species.
D) It addresses the formation of living cells from previously nonliving material.

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

mutations.Answer: B
