, chapter 1 biology and the tree of life
biological science, canadianA edition., 4e (freeman et al.)
1) the pattern component of the cell theory claims that all organisms consist of cells.
a) true
b) false
answer: a
explanation: the cell theory has two main components: the pattern component and the process
component. the pattern component states that all living organisms are made up of one or more
cells. therefore, it is correct that all organisms consist of cells, making this statement true.
reference: section 1.1
bloom's level: remembering
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.
answer: b
explanation: a scientific theory is a broad explanation that applies to many observations and is
supported by a large body of evidence. a hypothesis is a specific, testable explanation for a
particular observation. thus, theories are more general and comprehensive, while hypotheses
are narrower and address specific questions.
