Inquiry Into Life, 16e, Mader
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.
