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
