1 Biology and the Tree of Life
1) The pattern component of the cell theory.claims that all organisms consist.of.cells.
A) true
B) false.
Answer :.A
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 theoryis an explanation for.a very.general phenomenon.or.observation; hypotheses treat m
ore specific observations.
C) A hypothesis is an explanation for.a very general phenomenon; theories treat more specific iss
ues.
D) Theories define scientific laws; hypotheses are used.to set up experiments.
Answer: B
Reference: Section 1.1
Bloom's Level: Comprehension
LOs: Chp1-2. Describe the two components of the cell theory.
3) Algae.in the.genus Caulerpa typically grow.to a length of over.half a meter and have structures si
milar.to stems, leaves, and roots. Reproduction occurs when adults produce sperm and eggs that fus
e to.form offspring. Each adult Caulerpa, however, consists of just a single cell. Which of the follo
wing 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.
Answer: D

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.
Answer: C
Reference: Section 1.1 Bloom'
s Level: Remembering
LOs: Chp1-2. Describe the two components of the cell theory.
, 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 foll
owing criticisms would.be addressed by.using a swan-necked flask 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

C) red hair
D) lovefor.music
Answer: C

Bloom's Level: Comprehension
LOs: Chp1-1. Name five fundamental characteristics shared by all living.organisms.
7) How does artificial selection differ from natural selection?
A) Artificial selection occurs onlyin computer.simulations, not with actual organisms.
B) Artificial selection is based on conscious choices by humans.
C) Artificial selection.occurs only.with plants.
D) Artificial selection is not based on heritable variation, but on new mutations.
Answer: B

3. Briefly explain the theoryof natural selection, and clarify the two conditions that are necessary an
d sufficient for.natural selection to bring about evolutionary.change in.a population.
