osmosis and diffusion.
- What osmotic problems
are faced by organisms on land? In freshwater? In
the ocean? How are these problems solved?
- What is excretion?
What chemical is being disposed of? Where does it
come from? Why don’t plants worry about
excretion as much as animals do?
- What are the 3
excretory molecules? When is each used? What are
the advantages and disadvantages of each in terms
of toxicity, water use, and energy?
- What excretory organs
exist besides kidneys?
- How do other organs
contribute to homeostasis?
- What causes deserts
to spread?
- How are water balance
and thermoregulation linked?
- How are water balance
and gas exchange linked?
- Can you draw/explain the water,
phosphorous, carbon and nitrogen cycles?

Other study hints:
- Know the definitions of all
boldface terms in the text. Use the glossary and make
flashcards.
- Many figure in the book will be
important. Refer to your notes and study figures I mentioned in
class.
- Be able to give specific
examples in answering general questions.
- Be able to make simple,
logical mathematical calculations (calculators
permitted).
- Pay particular attention to
material on deserts and excretion that did not make it
onto the 2nd test. Regardless of how far we get in class, you will be
responsible for all reading on the current test.
- All tests are cumulative. You
will see questions from earlier tests on subsequent ones,
and entirely new questions on old material are possible
(but not likely).
- Essay questions will ask you
to expand on the objective material mentioned above, or
to explain in more detail why some phenomena develop;
i.e. why (how) does modern agriculture work?
- Many of the questions above
will be on the test but they may be altered - read
carefully!
- There will be other questions
on the test - read your notes and the book!
Re-write your
notes! - Ask questions in class! - Study with a friend. - Quiz
each other. - Get a good night's sleep before the test.
Study Hints
Try concept mapping: Get
some blank paper (try a recycling bin, use the back). Write down
a key term (biomagnification). Now, draw lines from the term to
blank areas on the page. Begin to add new information – 4
things that are necessary for biomagnification, 4 things that
biomagnify, etc. Make links to the new topics. Continue until the
paper is full. Start over with a new term.
Get in the Mood: Study
early and often. If you can’t find a quiet place, tune out
the background with lively, non-vocal music. A fast beat keeps
you motivated; vocal would distract from processing language
information (reading). Try Jazz or New-Age music, the same sort
of thing you would listen to for jogging. David Sanborn, David
Benoit, Peter White, Spyro Gyra, Mannheim Steamroller, even John
Tesh (really) are all good bets.
