BIO 182 EXAM 1 STUDY GUIDE WITH
COMPLETE SOLUTIONS
Key point # 1
Even the most disparate organisms share some features, suggesting that a single,
nonrandom process generated diversity. - Correct Answers -
Why is life so incredibly diverse yet so strangely similar? - Correct Answers -Evolution
How many species are there on planet earth? - Correct Answers -Probably between 3-5
million.
True or False? Biodiversity on Earth will likely decrease in the near future - Correct
Answers -True
What is the definition of natural evolution? - Correct Answers -evolution by natural
processes
What is the definition of creation? - Correct Answers -species created by a god
What is the definition of theistic evolution? - Correct Answers -evolution guided by a god
True or False? Scientists believe in evolution even though they currently lack evidence
for the theory. - Correct Answers -False
Key point #2 - Biologists accept evolutionary theory because its predictions match
observations. - Correct Answers -
Use this information to answer the questions below.
In ancient Greece, some scholars viewed irrational numbers as heretical. These
numbers could never be described perfectly because they ran on for an infinite number
of decimal places. The opponents of irrational numbers argued that a perfect universe,
designed by the gods, had no place for imperfect numbers. Ultimately, irrational
numbers played a major role in the development of mathematics, as evidenced by their
widespread use today. For example, the most famous irrational number, Pi, enables
one to calculate many properties of geometric shapes. - Correct Answers -
,Opposition to irrational numbers was based on evidence that such numbers cannot
exist.
a. True
b. False
c. I don't know the answer - Correct Answers -False - (No direct evidence for or against
irrational numbers was used to oppose the idea. A religious belief based on faith was
used instead.)
Opposition to irrational numbers stemmed from a worldview involving naturalistic
evolution.
a. True
b. False
c. I don't know the answer - Correct Answers -False - (A creationist worldview was the
reason for opposing irrational numbers.)
3. The belief that irrational numbers cannot exist reflects religion more than science.
a. True
b. False
c. I don't know the answer - Correct Answers -True - (The notion that God(s) created a
perfect world is the product of a religion)
4. Modern mathematicians accept irrational numbers because such numbers provide
more accurate solutions to problems than whole numbers do.
a. True
b. False
c. I don't know the answer - Correct Answers -True - (irrational numbers are used
because they enhance calculations of measurable properties, such as the area of a
circle).
Can you describe what we mean by science? - Correct Answers -Science literally
means "knowledge", being derived from the Latin word scientia. As with other scientific
disciplines, such as physics or chemistry, biology is the pursuit of knowledge about our
world. More specifically, biology is the pursuit of knowledge about life
, What are some of the key features of science? - Correct Answers -Scientists use the
following methods:
careful observation
record keeping
mathematical reasoning
experimental tests
review by peers
communication to the public
1. The scientific method relies on ____________.
a. models
b. observations
c. experiments
d. all of the above
e. I don't know the answer - Correct Answers -c. experiments
2. A model is a formal description of a scientific hypothesis. Which of the following types
of models provides the most precise description of a hypothesis?
a. verbal
b. graphical
c. mathematical
d. All of the above are equally precise
e. I don't know the answer - Correct Answers -c. mathematical
3. An experiment enables one to demonstrate that a correlation between two variables
results from cause and effect.
a. True
b. False
c. I don't know the answer - Correct Answers -a. True
4. A well designed experiment ___________.
Yes, that's correct!
