Name________________Biology Objectives Unit One

Answer all questions on a separate sheet, in order. Graphs, charts, and diagrams can be answered on this sheet.

1. Concerning the Characteristics of Life:a) What are the 7 characteristics used to define life? How many of these must

something do to be considered living?

b) Acquiring (getting) energy is one of the characteristics of life. Name every processyou can think of that is related to getting energy.

c) Define homeostasis and give 2 examples of things that are regulated by homeostasisin your body.

d) What is the smallest unit of life?e) What molecule, common to all living things, allows populations to evolve?

2. Concerning the Scientific Method:a) List the steps in the scientific method.b) Differentiate between a control treatment (group) and an experimental treatment.c) Explain the relationship between a dependent and independent variable. Which

would be on the x-axis of a graph of data?d) If you were testing the effectiveness of a drug, and you had separated your test

subjects into 2 groups, one group that received the drug and another who received aplacebo (sugar pill without medicine), which is the control group and which is theexperimental group? Name the independent variable. Choose an appropriatedependent variable, something that could be measured.

e) What 2 things can a scientist do if the hypothesis is not supported?f) Differentiate between objective and subjective statements and say which kind

belongs in science? Give 2 examples of each

3. Concerning the Universe:a) What are the two things that make up our universe, what is the basic unit of matter,

and how do you define matter?b) One cannot create nor destroy matter or energy. It is possible toc) Describe three subatomic particles, and say where they can be found in an atom

d) Differentiate between kinetic and potential energy and give an example of each.

4. Concerning water:a) Draw the structural formula for 2 water molecules. Include + and symbols to show

the polarity. Label the bonds.b) What is the difference between polar and non-polar molecules?c) Why do hydrogen bonds form between water molecules?d) Explain how ice can be less dense than liquid water. (Talk about kinetic energy andhydrogen bonds)e) Which of the following statements is TRUE: Water has an uneven electrondistribution. A polar molecule has charged regions. Water is a charged molecule.f) Describe cohesion

5. Concerning organic compounds:a) What are 3 characteristics all organic compounds have in common?b) Organic compounds are made by combining smaller, simpler molecules like using

bricks to build a cathedral. What are these organic building blocks called, what arethe complex molecules they make up called, and what is this called?

c) What process do organisms use to break down polymers to monomers? Describe it.d) What are the 4 categories of organic compounds that make up living things?
