A) true
B) false
Answer: A

LOs: Chp1-2. Describe the two components of the cell theory.
2) How does a scientific theory differ from a scientific hypothesis?
A) There is no difference—the terms are interchangeable.
B) A theory is an explanation for a very general phenomenon or observation; hypotheses treat
more specific observations.
C) A hypothesis is an explanation for a very general phenomenon; theories treat more specific
issues.
D) Theories define scientific laws; hypotheses are used to set up experiments.

3) Algae in the genus Caulerpa typically grow to a length of over half a meter and have
