Chapter 1 The Study of Life
1) Organs are composed of tissues, which are composed of cells. This is an example of which
characteristic of life?
A) Living things grow and develop.
B) Living things respond to stimuli.
C) Living things maintain themselves by homeostasis.
D) Living things have levels of hierarchical organization.
E) Living things are adapted to the environment.
Answer: D
Explanation: Organs represent one level in the hierarchy of biological organization but they are
a higher level of organization than either tissues or cells. The other answer choices are also
characteristics of life; however, the example is concerned specifically with levels of
organization.

,3) Which level of biological organization is composed of several tissues?
A) organism
B) organ system
C) organ
D) cell
E) molecules
Answer: C
Explanation: Organs are composed of tissues. Tissues are collections of cells, and cells are made
up of various molecules. Organs make up organ systems, which comprise the organism.

4) Which sequence correctly lists the different levels of biological organization, from the
smallest and simplest to the largest and most complex?
A) cells-organs-tissues-organ systems-organism
B) cells-tissues-organ systems-organs-organism
C) tissues-cells-organs-organ systems-organism
D) tissues-organs-organ systems-organism-cells
E) cells-tissues-organs-organ systems-organism
Answer: E
Explanation: The cell is the smallest unit of life. Cells are organized into tissues, which make up
organs. A group of organs working together comprises an organ system. An individual organism
contains multiple organ systems.

6) Which sequence of classification categories is in the proper order from least to most
inclusive?
A) genus, class, kingdom, domain, order, phylum, species, family
B) domain, class, genus, family, species, order, phylum, kingdom
C) species, genus, family, order, class, phylum, kingdom, domain
D) genus, species, order, class, family, kingdom, domain, phylum
E) species, genus, family, class, order, phylum, kingdom, domain
Answer: C
Explanation: The correct sequence is species, genus, family, order, class, phylum, kingdom,
domain. Species is the least inclusive category in the taxonomic hierarchy; domain is the most
inclusive.
