Biology 160 – Spring 2013
Study Guide for Test 2
The test will be multiple choice. You will need to bring:
❖ your own scantron from (the small kind from the bookstore).
❖ a HB pencil
❖ your UM ID #
No notes will be allowed. You are responsible for both the assigned readings and lecture
material.
From the text the test will cover the following chapters:
❖ Water and Life
❖ Carbon and the Molecular Diversity of Life
❖ The Structure and Function of Large Biological Molecules
You should review the associated Mastering Biology Assignments, and work over the
problems at the back of each chapter. Here are some questions to help guide your
studying.
Water and Life
Why is water polar?
It has been said that water is a “freak of nature.” That is, it behaves chemically very
different than it should given its size. Explain these statements.
What are the “emergent” properties of water?
Why are they important for life?
Be able to explain how these properties depend to a large extent on the polarity of water
molecules.
How do these properties influence life on earth?
Why does ice float? How does this relate to hydrogen bonding?
What is the difference between heat and temperature?
What is a calorie?
What is Avogadro’s number?
What is a mole?
How do you calculate molarity?
What is an acid?
What is a base?
How does the pH scale work?
Why is water such a good solvent?
What sorts of molecules dissolve easily in water?
What sorts of molecules don’t dissolve in water?
