CAMPBELL BIOLOGY CHAPTERS 1 – 5EXAM QUESTIONS WITH COMPLETE
ANSWERS
What is biology? - Answer-The scientific study of life.
7 characteristics of life? (Properties that we use to define what life is.) - Answer-1. Order
2. Regulation
3. Energy Processing
4. Evolutionary Adaptation
5. Response to the Environment
6. Reproduction
7. Growth and Development
Hypothesis vs. theory? - Answer-Hypothesis: A testable explanation for a set of
observations based on the available data and guided by inductive reasoning. A
hypothesis is narrower in scope than a theory.
Theory: An explanation that is broader in scope than a hypothesis, generates new
hypotheses, and is supported by a large body of evidence.
What is a controlled experiment? - Answer-An experiment in which an experimental
group is compared with a control group that varies only in the factor being tested.
What makes a good hypothesis? - Answer-...
How many variables can you test at once? - Answer-...
Quantitative vs. Qualitative data? - Answer-Quantitative data includes recorded
measurements which can be organized into tables or graphs and qualitative data would
include observations.
Inductive reasoning vs. deductive reasoning? - Answer-Inductive reasoning derives
generalizations from specific cases and deductive reasoning predicts specific outcomes
from general premises.
What is an element? - Answer-Any substance that cannot be broken down to any other
substance by chemical reactions.
What is a compound? - Answer-A thing that is composed of two or more separate
elements; a mixture.
, Characteristics of an element? - Answer-Atoms cannot be created or destroyed. The
elements can be divided into three categories that have characteristic properties:
metals, nonmetals, and semimetals.
Characteristics of a compound? - Answer-Compounds can be broken back into
elements by chemical reaction, exposure to light, etc. The mass of the compound is
determined by the mass of the elements that made it up. Compounds cannot be
separated by physical means: using magnet, filtration, etc. When compounds are
formed heat and light is given out or absorbed.
Which 4 elements make up the vast majority of the human body? - Answer-Carbon,

Electrons (-)
Where are the protons and neutrons located? - Answer-In the atomic nucleus.
Forms cloud around the nucleus. - Answer-Electrons.
What number defines the element? - Answer-Mass number
What unit are subatomic particles measured in? - Answer-Daltons.
What does the atomic number represent? - Answer-Number of protons in nucleus.
What values can we discern from the mass number? - Answer-Sum of protons +
neutrons in the nucleus.
What is an isotope? - Answer-2 atoms of an element that differ in number of neutrons.
How do you know when 2 atoms are isotopes? What number is different? - Answer-
They differ in numbers of neutrons and the mass number is different.
What is energy? - Answer-The capacity to cause change.
What is potential energy? - Answer-The energy that matter has because of its location
or structure.
What is kinetic energy? - Answer-The energy of motion.
