D. ENDOCYTOSIS – cell encloses material (in-cludes phagocytosis of solid particles); a form of active transport
E. EXOCYTOSIS – cell discharges vacuole- enclosed material; a form of active transport
METABOLIC AND ENERGY-PRODUCING PATHWAYS
A. ENZYME – protein catalyst speeds reaction by lowering energy of activation1. Substrate – molecule on which enzyme acts2. Coenzyme – binds briefly to enzymes;
activates and assists enzymes3. ATP – adenosine triphosphate; energy stored
in phosphate-phosphate bonds; energy released when bonds are hydrolyzed
4. NAD – nicotinamide adenine dinucleotide; part of electron transport system
B. PHOTOSYNTHESIS – chloroplasts – 6CO2 + 6H2O + (light, chlorophyll) → C6H12O6 + 6O2
C. CELLULAR RESPIRATION – generates ATP1. Glycolysis – initial stage of respiration –
cytoplasm – anaerobic – activation of glucose (by ATP), with production of pyruvate (net gain of 2 ATP)
2. Krebs (citric acid) cycle – second stage of respiration – mitochondria – aerobic – pyruvate broken down with production of CO2, 2 ATP, and many electron carriers
3. Electron (hydrogen) transport chain – third stage of respiration – mitochondria – aerobic – hydrogen and electrons stripped from carriers with production of 32 ATP
DNAA. NUCLEOTIDES – subunits of nucleic acids
1. Phosphate2. Sugar (deoxyribose in DNA, ribose in RNA)3. Nitrogenous base (four in DNA): Adenine (A),
Thymine (T), Guanine (G), Cytosine (C)

B. STRUCTURE OF DNA1. Sugar-phosphate groups – sugar is deoxyri-
bose2. Nucleotides3. Double helix – sugar-phosphate groups form
backbone (sides of “ladder”), pairs of nucleo-tides form “rungs of ladder”; nucleotide pairs joined by hydrogen bonds; A always pairs with T, C always pairs with G
MOLECULAR GENETICSA. DEFINITIONS
1. Gene – a location on a chromosome; typi-cally codes for one polypeptide
2. Alleles – different forms of a gene3. Chromosome – structure made up of DNA
and associated proteins4. Genotype – genetic makeup of an organism5. Phenotype – visible expression of genetic
makeup
CLASSIFICATIONA. LEVELS OF TAXONOMIC CLASSIFICATON

Kingdom Animalia(multicellular)
CELL BIOLOGYA. CELL THEORY
1. All living things are made up of one or more cells.
2. The cell is the basic unit of structure and function.
3. All cells come from existing cells.B. PROKARYOTIC CELL STRUCTURE
1. Plasma membrane – regulates what enters and leaves the cell
2. Flagellum – locomotion3. Ribosomes – sites of protein production
(RNA) – protein synthesis4. Pili – used for attachment to other bacteria
or to a host5. Plasmid – small circle of DNA separate from
main chromosome loop6. Cell wall – protection and support

C. EUKARYOTIC CELL STRUCTURE 1. Plasma membrane – regulation of internal
environment 2. Mitochondria – membrane-enclosed –
energy-producing reactions 3. Chloroplasts – plants – photosynthesis 4. Lysosomes – storage for digestive enzymes 5. Smooth Endoplasmic reticulum (SER) –
protein and lipid synthesis 6. Rough Endoplasmic Reticulum (RER) – pro-
duces, modifi es, and transports proteins – has ribosomes attached
7. Ribosomes – particles composed of ribo-nucleic acid (RNA) – protein synthesis
8. Golgi apparatus – stores, modifies, and packages secretory products
9. Peroxisomes – contain oxidative enzymes10. Vacuoles – fl uid-fi lled spaces – storage11. Cell wall – plants – protection and support
12. Centriole, centrosome – animal cells – cell division
13. Cilia, fl agella – locomotion and ingestion14. Nucleolus – in nucleus – ribosome synthesis

D. LIMITATIONS ON CELL SIZE – As cell size increases, surface area-to-volume ratio increases. If the ratio becomes too high, the cell surface is not large enough to carry out its function. It can-not allow materials into or out of the cell quickly enough to support necessary life processes.
E. STRUCTURE OF THE CELL MEMBRANE
EXCHANGE BETWEEN CELL AND ENVIRONMENT
A. DIFFUSION – movement of ions or molecules down a concentration gradient
B. OSMOSIS – movement of water molecules across a membrane down a concentration gradient1. Isotonic medium – same solute concentra-
tion as cell2. Hypertonic medium – higher solute concen-
tration than cell; cell loses H2O (shrinks)3. Hypotonic medium – lower solute concen-
tration than cell; cell gains H2O (expands)C. ACTIVE TRANSPORT – movement against
a concentration gradient; requires energy input from cell

Take Control of the Common Core with REA’s PARCC Assessment ELA Study Guides
The educational landscape is changing and REA is at the forefront of the new PARCC (Partnership for Assessment of Readiness for College and Careers) assessments that millions of students will soon face. These targeted study guides are designed for teachers and students in PARCC states and are fully aligned with the Common Core standards.
n Covers Must-Know PARCC Performance-Based Tasks: Each chapter includes step-by-step instruction and practice for every topic tested on the PARCC English Language Arts/Literacy exams.
n Written by an Expert: Our author is a curriculum expert who has studied the format and content of the Common Core standards and the PARCC ELA guidelines. Each lesson follows the Common Core standards.
n Handy Guides for Students and Teachers: These books bring the Common Core down to the classroom level, deciphering what it all means to the way students are taught. Our author gives teachers practical guidance on how the ELA/Literacy assessments should shape their teaching methods and lesson plans.
What Are the Common Core State Standards (CCSS)?
The Common Core State Standards Initiative is a state-led effort coordinated by the National Governors Association Center for Best Practices and the Council of Chief State School Officers. The standards provide teachers and parents with an understanding of what students are expected to learn. Consistent standards provide appropriate benchmarks for all students, regardless of where they live. These standards define the knowledge and skills students should have within their K-12 education so they will graduate high school and be able to succeed in entry-level, credit-bearing academic college courses and in workforce-training programs.

“ This book (AP U.S. History Crash Course) saved me hours of studying and helped me achieve a 5 on my AP exam. My whole AP class went out and bought it, and it helped us all.” — R. Amalfitano, AP Student, Ridgefield Park, NJ
“ If it had not been for the AP Crash Course, our students would have been discouraged and floundered. The book is a marvelous tool that helps students make connections and see relationships that cement their learning. The author skillfully includes proven hints and pivotal topic summaries. The AP Crash Course is not only a tool for test preparation, but a study companion to consult as the course develops.”

The ACCuplACER is a computer-adaptive placement exam taken by over 2.5 million college-bound students each year. The test is given by high schools, technical schools, community col-leges, and four-year colleges to determine the English language, writing, and math skills of incoming students.
The COMpASS is a computer-adaptive college placement exam used by high schools, technical schools, community colleges, and four-year colleges across the country. It evaluates the English language, writing, and math skill levels of incoming students. Last year, approximately 2.5 million students took the exam.
In January 2014, the GED Testing Service® is launching an entirely new GED® exam. This new computer-based assessment will provide adults the opportunity to earn a high school equivalency diploma, in addition to measuring career- and college-readiness skills.
REA’s new GED® test preps are completely aligned with the content and format of the 2014 exam. Comprehensive reviews plus full-length practice exams help students prepare for the new exam and succeed in their educational goals.

preparing for The asVab
By reviewing and studying this book, you can achieve a top score on the ASVAB. The ASVAB
assesses knowledge that you’ve gained throughout your high school career. Most of the knowledge
tested on the ASVAB is covered in your high school classes, although you may find some unfa-
miliar or less studied subjects. Don’t panic! We provide carefully constructed reviews and practice
drills so you can learn the information you’ll need to do well on the ASVAB.
The purpose of our book and TestWare® is to properly prepare you for the ASVAB by providing
a diagnostic test plus three full-length exams that accurately reflect the test in both types of questions
and degree of difficulty. The practice exams include every type of question that can be expected, and
detailed explanations are provided for every answer. Designed specifically to clarify the exam mate-
rial, the explanations not only provide the correct answers, but also tell you why a particular answer
is more acceptable than any other response. The TestWare® offers the added benefit of enforced time
conditions to more accurately reflect your experience on test day. By completing all the exams and
studying the explanations, you can discover your strengths and weaknesses. This knowledge will
allow you to concentrate on the sections of the exam you find most difficult.
You can take the ASVAB as early as your sophomore year in high school. If
you take the ASVAB as a sophomore your score will not be used for joining
the military. If you have to take the test again, you can retake the ASVAB after
30 days, and again 30 days later.

4 Armed Services Vocational Battery
Once you take the test, you and your guidance counselor or your recruiter will receive a written
report that analyzes your test scores and explains in what elds you might excel based not only on
the test scores, but also on the type of interests and lifestyle you wish to pursue.
If you have a question about your scores, you can contact your local military recruiting of ce,
or speak to your guidance counselor.
There are three versions of the ASVAB:
MET-Site ASVAB : Paper-and-pencil test administered by military recruiters at a satellite test site.
CAT-ASVAB : Computer-adaptive test administered by military recruiters at a Military Entrance
Processing Station (MEPS).
Student ASVAB: Paper-and-pencil test administered in high school.
ASVAB Test Content
The ASVAB contains eight, nine, or ten subtests (or sections), depending upon which version
of the ASVAB you take, each of which is individually scored. The following chart shows you the
subtests you will encounter and gives a brief description of each, as well as the time allowed and
the number of questions.
The ASVAB was originally designed to predict future academic and
occupational success in military occupations. Since it was introduced in
1968, studies indicate that the ASVAB assesses academic ability and predicts
success in a wide variety of occupations.
BACKGROUND REPORT
There’s no pass or fail on the ASVAB. You can’t “beat” it or “fl unk” it and
ASVAB scores are good for two years.
INTELLIGENCE REPORT
Your scores in four critical areas—Arithmetic Reasoning, Word Knowledge, Para-
graph Comprehension, and Mathematics Knowledge—count toward your Armed
Forces Qualifying Test (AFQT) score. The AFQT score determines whether you’re
qualifi ed to enlist in the military. Your scores on the other subtests will determine
how qualifi ed you are for certain military occupational specialties.
INTELLIGENCE SUMMARY
The ASVAB, given at more than 14,000 schools and Military Entrance Processing Stations
(MEPS) nationwide and developed and maintained by the Department of Defense, is the most widely
used multiple-aptitude test battery in the world. The ASVAB is required by the Armed Forces for
new recruits joining one of the branches of the military following high school. The scores aid in the
placement of recruits into military occupations. The scores are also helpful, but not a requirement, in
choosing an academic or vocational plan to be followed after high school graduation.

2Getting Around
No car? No problem!
There are plenty of ways to get
around. Most cities and towns have
an effi cient mass transit system; that
is, they have buses or trains to get
you where you need to go.
Often, you may need to take a bus
to the train station. Sometimes it can
be complicated to figure out which bus or train will take you where, but
there is help! Most cities have a special department just to provide that
information. You can call the transit company to ask. When you call the
company, you will need to tell them where you are and where you need
to go. You can also ask if you need exact change for the bus. Drivers
usually can’t accept cash.

Introduction
The Life and Work of George Orwell
George Orwell was born Eric Hugh Blair in 1903 in Motihari,
Bengal, India. He was the second of three children, and the only
boy, born to Richard and Ida Blair. His elder sister, Marjorie, and
his younger sister, Avril, completed this middle-class Anglo-Indian
family. His dour, discouraging father was an agent in the Opium
Department of the British Civil Service. As was the custom with such
middle-class children born abroad, he was sent back to England
for his education. His mother, a modern, rather left-wing woman
and militant suffragette, accompanied him.
Orwell attended the best English schools, including Eton Col-
lege (1917-1921), a school that epitomized “traditional” British
education. Poorer than the other students and feeling insecure
about himself, he never quite fit in with the rest of his classmates.
Politically, he had difficulty accepting the world of British imperi-
alism that surrounded him. These feelings of being an “outsider,”
coupled with Orwell’s firm belief (which he expressed early in his
life to friends and family) that he felt fated to become a “great
writer,” affected the course of his entire life. Influenced by his
mother’s “revolutionary” politics and charged by his own political
ideas, Orwell ultimately turned to a writing career.
However, when he graduated from Eton College in 1921, Orwell
briefly followed the family tradition and entered civil service as a
member of the Indian Imperial Police in Burma. He served in this
position from 1922 to 1927, gathering material for his two most

STRONGER: Due to its strong focus on sustainability, water efficiency, and indoor environmental quality, interest in the LEED certification program will continue to grow.WEAK: The film Crash makes important statements about sociology. (This thesis statement is vague and needs more details.)STRONGER: The film Crash presents several examples of social dysfunction and social conflict that invite a discussion of how this movie about Los Angeles relates to sociology throughout the United States.As you work through the writing process and find out more about your writing topic, you may find that you need to add to or revise your thesis. Because of this, the first statement that you draft is most likely your working thesis.
Organizing ideasAs you do preliminary research for an essay or research paper, you might draft notes of ideas or facts you discover about your topic. It can be helpful to look over your notes and use an organizational method to group notes of a similar topic together. Here are a few different methods: Clustering – Clustering is a visual technique used by writers to come up with ideas for a chosen topic. This organizational method visually resembles a spider’s web, displaying one central idea in the middle with related ideas spiraling out from the center. The example below shows how a writer used clustering to come up with ideas for a paper on the value of a college education.

idea Cards – To use this organizational technique, begin with 3by5inch index cards. Start jotting down ideas related to your topic on the cards. Make a game out of it by spreading out all the cards and arranging and rearranging them according to subject matter. When your ideas seem organized in a logical order, arrange your cards into a deck. Flip over one idea at a time and convert the ideas into complete sentences on another sheet of paper.Color Coding – Color coding related ideas will help you locate information easily when you begin drafting your essay. After you have jotted down all of the supporting points you want to make to prove your thesis, highlight the ideas that go together. This will make it easier to break down your information into paragraphs. You can also use multicolored index cards, keeping related ideas on the same colored cards.
The WriTing PrOcessAny college writing assignment involves a 5step process. 1. Planning – Includes deciding on a topic and
brainstorming about the topic by collaborating with a teacher and/or peers, freewriting, writing in a journal, and/or making graphic organizers containing ideas you gather about the topic.
2. drafting – During this stage, string the ideas from your planning stage together into an essay. Begin to create paragraphs. Flesh out your main ideas by providing definitions and examples.
3. revising – After creating a rough draft, let it sit for a few hours. Then go back and add any new ideas or details, or rearrange ideas that may not flow properly. You could ask a trusted peer to read your work and give you feedback. This is the stage to add, delete, or rearrange entire paragraphs.
4. editing – At this stage you are ready to focus on each sentence of your essay. Look at your word choices: have you used too many words? Do you need to use more precise words? Are your sentences too lengthy or dense? Too short or choppy? Do you need to add transitions between paragraphs and/or sentences?
5. Proofreading – Now you are ready to look closely at the spelling, punctuation, capitalization, and grammar within your paper. Also check the formatting conventions you’ve used, either MLA (Modern Language Association) or APA (American Psychological Association). Consult a style guide if you are unsure of how to cite resources.
chOOsing a subjecTIf possible, choose a subject that you will enjoy learning about. Ask yourself a few questions:
• What do I want to learn more about? • What subjects do I care about? • How will learning about this topic be helpful
to me? After you’ve chosen a general topic, you may need to either broaden it or narrow it down. Consider these questions if you are writing a fiveparagraph essay:
• Will you be able to write at least five paragraphs related to the topic?
• Will five paragraphs be enough to cover the topic?
If you’ve answered “no” to either of these questions, you’ll need to either broaden or narrow your topic.
cOnsider The audienceThink about details you will need to include to suit your audience. Ask these questions as you plan and draft your essay:
• What does the audience already know about the topic? What do I want my readers to learn?
• How much detail does my audience need to know about the topic?
For example, if you are writing an essay about the differences between baseball’s American League and National League, you will need to know how much your readers know about baseball. If they have never heard of these different leagues, you will need to include details that explain the leagues themselves before you begin explaining similarities and differences.
Other questions:• What will be convincing to my audience?• What will my audience object to?• How can I write the essay to overcome any
objections my audience may have?For example, if you are writing an essay to an audience of zookeepers persuading readers that elephants do not belong in zoos, you should not imply that the treatment elephants receive in zoos is at fault, because this will insult zookeepers. Instead focus on statistics from many different zoos that demonstrate how elephant fertility decreases in captivity.
idenTify The PurPOseAlways keep your purpose for writing in mind, from start to finish of the writing process. Many college writing assignments are drafted for the following reasons:
• to narrate a story and interpret its importance
• to describe an event and explain its significance
• to explain a policy and determine its effect• to argue a position and persuade others to
agreeYou may draft an essay that uses one or more of these purposes within it. For example, you may have one or two paragraphs in your essay that narrate a story, yet the reason that the story is included in your essay is to serve the purpose of convincing readers.
sTrucTure Of an essayAn essay is made up of three parts:1. introduCtion – The introduction usually
opens with an interesting story or quote that catches the reader’s attention. The story then leads into a thesis statement that presents the main idea of the essay.
2. Body – The body is made up of several paragraphs that support the ideas presented in the thesis statement. Most writing assignments require you to write at least three body paragraphs. The body contains the details, facts, and events that support an argument or that describe an experience.
3. ConClusion – The conclusion restates the thesis statement and revisits the main ideas presented in the body. It serves to close up the writer’s arguments and leave the reader with a concise review of the material covered in the essay.
WriTing a Thesis sTaTemenTBefore you begin writing an essay or writing a research paper, draft a working thesis statement. The thesis statement should contain two parts: (1) the subject of the essay and (2) your opinion about the subject. Be sure to write a thesis statement that is specific enough to be interesting to your reader. Here are some examples of strong and weak thesis statements:WEAK: High school dropout rates are increasing. (This thesis statement lacks an opinion, and it is too general.)STRONGER: Because higher education is needed more than ever before for members of today’s workforce to be successful, rising numbers of high school dropout rates are harmful to society. WEAK: LEED construction is the wave of the future. (This thesis statement lacks specific details that will make the essay appealing to the reader.)

LINEAR EQUATIONS AND SYSTEMS OF EQUATIONS
A. LINEAR EQUATIONS IN ONE VARIABLE
1. Defi nition : an equation with one variable of the form ax + b = 0, a and
b are constants, a ≠ 0.
2. Solving linear equations in one variable: Using the properties of equal-
ity, a linear equation of the form ax + b = 0 can be solved as
x = − b __ a .
3. Graphing the solution of a linear equation in one variable: The
solution of a linear equation in one variable x (or y ) is graphed as a
vertical (or horizontal) line. The equation x = 3 specifi es the value of
x but it does not put any limits on y so the graph is all the points (3, y ).
A horizontal line ( y = a ) is said to have zero slope and a vertical line
( x = a ) is said to have no slope .

2. Features of a line: The graph of a linear equation has two important
features.
A. Slope : If a line passes through the points ( x 1 , y 1 ) and ( x 2 , y 2 ), then
the slope of the line is determined by the equation:
m = y2
− y1 ______ x2
− x1 .
B. Intercepts: The intercepts are the points at which a line intersects
the x - and y -axes. The x -intercept is of the form ( x , 0) and the
y -intercept is of the form (0, y ). Most lines will have both an x - and
a y -intercept, with the exception of horizontal lines, vertical lines,
and direct variations.
