Exam Review #1 (Chapters 1 through 3)
The exam reviews are worth 20 points each and are part of your grade. You will need to look up either the definitions of different terms, list and describe or answer questions about different topics in each chapter. These questions vary in points depending on the specific question. Be sure to answer all of the questions! The exam reviews do not cover every question that will be on the exam but serve as a review of each chapter on the exam. The exam review must be submitted before the due date and must be submitted as a Word document.
Chapter 1
- Identify four characteristics of life.
- Define homeostasis
- How do prokaryotic and eukaryotic cells differ?
- Define the term evolution.
- Outline the steps of the scientific method.
- Recognize the appropriate characteristics of a controlled experiment.
- Distinguish between a theory and a hypothesis.
- Distinguish between basic science and applied science.
Chapter 2
- Distinguish between the types, location and charge of subatomic particles. (Must answer all parts of the question for full credit.)
- Identify the four elements common to all living organisms.
- The atomic number is determined by the number of _______________, which is unique to each atom.
- The atomic mass tells you the number of ___________ and the number of __________ which is specific to each atom.
- How are cations and anions formed?
- Contrast ionic and covalent bond characteristics.
- Interpret the pH scale.
- Explain the purpose of a buffer.
Chapter 3
- Define dehydration synthesis and hydrolysis.
- How are monosaccharides, disaccharides, polysaccharides structurally different from one another?

Exam Review #1 (Chapters 1 through 3)
Chapter 1
1 Identify four characteristics of life.
* Metabolism: the ability to convert energy from one form to another, usually involving the breakdown of complex molecules into simpler ones.
* Growth: the ability to increase in size or number.
* Response to stimuli: the ability to detect and respond to changes in the environment.
* Reproduction: the ability to produce offspring.
2 Define homeostasis
Homeostasis is the ability of an organism to maintain a stable internal environment. This can be accomplished by regulating the body's temperature, blood pressure, and other vital functions.
3 How do prokaryotic and eukaryotic cells differ?
Prokaryotic cells lack a nucleus and eukaryotic cells have a nucleus. Prokaryotic cells lack a cell wall and eukaryotic cells have a cell wall. Prokaryotic cells lack a cell membrane and eukaryotic cells have a cell membrane. Prokaryotic cells lack a organelles and eukaryotic cells have organelles.
4 Define the term evolution.
Evolution is the process of change in the heritable characteristics of a population of organisms over successive generations.
5 Outline the steps of the scientific method.
1.Formulate a question or hypothesis
2.Collect data to test the hypothesis
3.Analyze the data to determine if the hypothesis is supported
4.Make a decision based on the results of the analysis
5.Repeat steps 2-4 until the hypothesis is proven false or the data no longer supports it
6 Recognize the appropriate characteristics of a controlled experiment.
A controlled experiment is an experiment in which the researcher controls the conditions under which the experiment is conducted. This means that the researcher can ensure that the variables under study are the same for all participants in the experiment. Controlled experiments are also often randomized, which means that the order in which the participants are assigned to the different conditions is randomized.
7 Distinguish between a theory and a hypothesis.
A theory is a well-substantiated explanation of an aspect of the natural world that is supported by a vast amount of evidence. A hypothesis is a proposed explanation for a phenomenon.
8 Distinguish between basic science and applied science.
Basic science is the study of the fundamental principles of a particular discipline. Applied science is the practical application of the principles of a particular discipline.

9 Distinguish between the types, location and charge of subatomic particles. (Must answer all parts of the question for full credit.)
There are three types of subatomic particles: ...
