Biology 1210
ADDITIONAL STUDY QUESTIONS #1 (Ch 1 and 2)
While it may seem a bit abstract initially, I think this pattern detection exercise is a good way to wake
up your "compare and contrast" skills. Complete the following by filling in a letter, number, or word
in each blank. Set a timer and record how far you get in 10 minutes and your total time.

Can you see how the strategies you used here (compare and contrast!) can help you study and learn?
Ok no more abstract learning stuff, lets roll up our sleeves and learn some BIOLOGY!!!!
CHAPTER 1
Read the whole chapter but focus on details in 1.7. The other sections will make more sense as we go
along. They are an overview of where we are going. Do the problems in back of chapter. Quizzes on
CD are also good way to study. After you have read the chapter, answer the problems at the end as if
they were a quiz (no text, no notes, no distractions). How do you think you did? Before you check
the answers, go back to text and find the information. Working backwards from 'known' answers is
NOT a good way to study.
1.
a. What is Biology? Define "Life". Try to write your own definition first. Then reread module
1.2. List as many of the qualities you can remember. Repeat as necessary.
b. Make a table with the eight properties listed in section 1.2 and several columns (ie. you,
plant, bacteria, virus, rock) What basic properties do living things share?
c. The information in ______ (what type of molecule) underlies all of the properties that
distinguish life from nonlife.
d. Do some viruses contain this molecule (in c)? Are viruses alive? Why or why not.
e. Are tomato plants alive? Are tomatoes alive? Are sperm alive? Are oocytes (eggs) alive? Is
a one cell, fertilized human embryo alive? As you can see, definitions are not simple. Boundaries and
relationships are fuzzy. Regardless, it is important to explore concepts with questions: i.e. When does
human life begin? At conception? When the heart begins beating? When brain activity starts? When
does human life end? When the heart stops? When brain activity stops?
2. see pages 2 & 16 Into what three domains do biologist classify living organism? (Sounds like a
jeapordy question!) Prokaryotes are in which domain(s)? Which two domains contain only one
kingdom? How are those two domains different from the third? (We will learn how they are different
from each other later.) What are the kingdoms in Eukarya? Keep your answers to 1 & 2 in view as
you learn more this semester. Use them as a starting point for concept diagrams.

organization, define each term and give an example. (a good way to study)

be falsified?

e. 4 times more
c. 100 times less
f. 100 times more
20. Which of the following is NOT a chemical reaction?

b. Sodium metal and chlorine gas unite to form sodium chloride.
c. Hydrogen gas combines with oxygen gas to form liquid water.
d. Solid ice melts to form liquid water.
e. Sulfur dioxide and water vapor join to form sulfuric acid.
21. Animals obtain energy through a series of chemical reactions in which sugar (C6H12O6) and
oxygen (O2) are reactants. This process produces water (H2O) and carbon dioxide (CO2) as waste
products. Suppose you wanted to find out whether the oxygen in CO2 comes from sugar or oxygen
gas. How might you find out?
(Hint: number of neutrons)
22. List the biological issues that you have heard about in the news last week. (This might be a good
bonus question). Now pay attention and keep a list of biology stories in the news. This is a good way
to figure out what you think is interesting, important etc. As the semester progresses, hopefully you
will notice more and more.
(I'll put a key at reserve desk and electronic reserve but sometimes
it takes a few days…to prevent working backwards from answers!)
