Ap Biology Chapter 53 Reading Guide Answers

feature_apbiologyreview.jpg

Reviewing for the AP Biology exam can seem daunting. There's so much fabric to cover, and much of it is highly complex. Yet, if you lot plan your fourth dimension well and use appropriate study materials and strategies, you can expect a bully score on the test.

In this commodity, I'll requite you an overview of what the AP Biological science examination is like, what you need to know to ace information technology, and how you can apply your study time finer before the exam on Wednesday, May 11, 2022, at 12PM!

What's the Format of the AP Biology Test?

The AP Biology exam is a long examinationthree hours long to exist exact. Starting in 2020, the Bio exam underwent some key structural changes in terms of questions and format, and then it'south important that you know what to await and exactly how the exam is structured.

Like other AP tests, AP Biological science has ii parts: a multiple-option section and a costless-response section, each of which is worth 50% of your overall score. These sections are then divided further into dissimilar types of questions.

The multiple-choice section is the offset section. Information technology consists of lx multiple-choice questions and is one hour and xxx minutes long. Each question contains four answer choices. (From 2013 to 2019, this section of the AP Bio test had 63 multiple-selection questions and half dozen grid-in questions.)

Although you have i minute for each question, I would recommend keeping your step at under a minute per question on your first pass through the section. This way you'll have some actress time at the finish to go back and answer whatsoever tricky questions you skipped or guessed on.

There'southward no guessing penalty on the test, so y'all should answer every question, even if you have no idea which selection is correct (later on you've tried to figure it out of course!).

The free-response section, which also lasts an hour and 30 minutes, is made up of six questions: four short-answer questions and two long questions. The short-answer questions are worth four points each, whereas the long questions are worth 8-10 points each. (From 2013 to 2019, this Bio section had ii long questions and half-dozen brusque-respond questions.)

You'll need to pace yourself wisely on this section. Divided upward evenly, this would mean you'd go 15 minutes per question. However, try to spend no more than x minutes on each short answer. I recommend doing the short answers first to get yourself warmed up.

Then, if you manage your time well, y'all should accept at least 20-25 minutes for each long gratuitous-response questions.

Hither'south a chart showing the current format of the AP Biological science exam:

Multiple-Choice Department Free-Response Section
Time xc minutes 90 minutes
# of Questions 60 multiple-selection questions 4 brusk-reply questions, two long questions
Percent of Total Score 50% fifty%

And but to make things clear, here'southward what the examination used to look like from 2013 to 2019:

Multiple-Pick Department Free-Response Section
Time ninety minutes 90 minutes
# of Questions 63 multiple-pick questions, half dozen grid-in questions 6 short-answer questions, 2 long questions
Percent of Total Score 50% l%

What Practice Questions Await Like on the AP Biology Examination?

Yous now know the general format of the AP Biology test, but what practice questions actually await like on information technology? And what kinds of topics practice they test? Let's take a expect.

Multiple-Choice Questions

Equally a reminder, there are 60 multiple-option questions on the AP Bio exam. These can exist discrete (meaning they are stand-alone questions) or they can come in sets with other questions.

Here'south an case of a multiple-pick question yous might run across on the exam:

body_apbiomc.png

You lot don't necessarily need lots of in-depth biology knowledge to respond this. The answer is A considering the total book of gas wouldn't change (and oxygen consumption would be immeasurable) unless the carbon dioxide produced by the organisms were removed from the environment.

Y'all can see this from the data contained in the question. This question is part of a group of three questions that pertain to the experiment and data chart. You'll come across many question clusters like this in the multiple-selection section.

Filigree-In Questions

From 2013 to 2019, the multiple-choice department of the AP Biology exam included six math-based grid-in questions. Starting in 2020, even so, the exam will no longer have whatever grid-ins. Yay!

Brusk-Respond Questions

On the second section of the AP Biological science test, you'll get four short-answer questions (in addition to two long questions). These questions focus on the post-obit topics:

  • Scientific Investigation
  • Conceptual Analysis
  • Analysis of Model or Visual Representation
  • Assay of Data

Here's an case of a short free-response question from the 2013 exam:

body_shortfreeresponseapbio.png

This question requires an understanding of how evolution shapes the formation of new species.

To get the correct answer, you'll demand to know the facts almost evolution—simply you'll also need to exist able to apply that knowledge to make inferences nearly this specific scenario.

This is why a deeper understanding of the master topics in AP Biology is so disquisitional: the difference betwixt knowing the facts about something and comprehending how information technology works can be surprisingly big.

Long Questions

In addition to the four short-answer questions yous'll become on the second function of the AP Bio exam, you'll get two long questions. Both of these focus on "interpreting and evaluating experimental results," with 1 requiring graphing (per the College Lath description).

Here'due south an example of a long question:

body_longfreeresponse.png

This question is heavy on assay and isn't just testing your straight-upward biology knowledge. Here, you need to be able to read and sympathize the graphs and tabular array so you can utilize them to inform your answer to the question.

Once once more, an agreement of development and the power to use that noesis to a specific scenario is critical.

What Topics Does the AP Biology Exam Cover?

According to the College Board's Form Description, AP Bio has shifted its focus from the content-heavy, memorization-based curriculum that defined the form and examination in the by to get a more concept-driven exam.

The goal is for students to gain a deeper conceptual understanding of topics in biology. Reasoning skills and knowledge of the process of scientific inquiry are more than important on the current version of the AP Biological science test than they take ever been earlier.

The Higher Board has tried to structure the exam and so that content knowledge and reasoning skills are intertwined. This can exist both good and bad. The skilful is that y'all won't necessarily have to memorize equally many little tidbits of information; the bad is that information technology can be harder to study for a test like this that covers more abstract forms of knowledge. (More on how to manage this in the "How to Review" department!)

The AP Bio examination and curriculum as a whole volition be centered around eight major units. Hither they are:

Unit 1: Chemistry of Life
Unit two: Jail cell Structure and Function
Unit iii: Cellular Energetics
Unit iv: Cell Communication and Cell Cycle
Unit 5: Heredity
Unit 6: Gene Expression and Regulation
Unit vii: Natural Selection
Unit 8: Environmental

The Importance of Labs

Apart from background knowledge of all this content, it's important to sympathize your labs and the bones underlying principles that govern scientific experiments. If you know the ins and outs of experimental blueprint, you'll earn a lot of points on the AP Bio exam.

Important lab topics include the following:

  • Artificial Pick
  • Modeling Evolution
  • Comparing DNA Sequences
  • Diffusion and Osmosis
  • Photosynthesis
  • Cellular Respiration
  • Mitosis and Meiosis
  • Bacterial Transformation
  • Restriction Enzyme Assay of DNA
  • Energy Dynamics
  • Transpiration
  • Fauna Behavior
  • Enzyme Catalysis

AP Biology Review Preview: 4 Fundamental Tips to Go on in Mind

In this department, I'll give yous some preliminary study tips that will help you get the most out of your AP Biological science review time.

Tip 1: Program Out Your Time

First of all, you should retrieve well-nigh how much time yous have left earlier the AP test. This will affect the structure of your study plan. If you're taking other AP classes or have a lot of personal commitments in general, you might want to start earlier depending on your confidence with the material.

Consider your schedule and the fourth dimension you're willing to spend on AP Biology. Since there'south so much content in this course, I think 20 hours of studying is a reasonable goal. However, if you find that you lot're already scoring at a high level (a high four or anywhere in the five range), you might aim for just ten hours or so.

You should balance your fourth dimension relatively evenly between studying the material and taking practice tests. In AP Bio, you might benefit from devoting a scrap more time to practice testing.

Since the examination is now more than targeted toward assessing analytical skills, practicing real test questions might assistance you more than merely memorizing content (although both are yet important!). I'll give you more information about how to employ practice tests and review materials effectively in a moment.

Tip ii: Utilise Appropriate Review Materials

The importance of using the correct review materials can't exist overstated, specially in the example of AP Biology. With the recent changes to the test, information technology'south critical that you don't use old study materials and presume that they'll requite you all the tools you need to succeed on the new format.

Some review books students have institute the most useful include CliffsNotes' AP Biology for content review and Sterling'due south AP Biology Practice Questions for practice questions that requite yous a good sense of what the examination is like.

Avoid using practice questions that come from exams before the 2013 test, when some of the more drastic changes were implemented. You might even so be able to apply older questions to refresh your memory on certain topics, simply they won't actually prepare you for the more than belittling framework of questions on the current AP Biology exam.

Furthermore, the College Board at present offers a great online resource called AP Classroom, through which students can interact with teachers, complete homework and get feedback on assignments, and receive access to review materials for the AP Bio test, including existent practice questions. Yous'll use your Higher Lath student business relationship login credentials to access AP Classroom, and one time logged in, you can admission a different section for each AP class y'all're taking.

Tip 3: Memorization Isn't Enough

Even though AP Biology however involves a fair corporeality of memorization, you can't focus exclusively on content knowledge and just presume you lot'll practice nifty on the test.

AP Bio questions will test your critical-thinking skills and logical reasoning abilities, along with your general knowledge of biology. That'due south why it's so of import that you spend a meaning amount of time doing practice questions in add-on to content review. Don't let the examination surprise you!

Tip iv: Don't Forget Most Labs

Revisiting onetime labs is non super fun (well, it wasn't for me), so y'all might be tempted to ignore them and merely focus on studying content outside the lab context.

Try to avert this temptation! Go through your labs, and make sure that you understand their methodologies and the reasoning behind the results. Understanding the scientific method and the components of a good experiment is key to acing the AP Bio exam.

The more lab review you do, the more comfortable you'll feel during the test.

How to Review for the AP Biology Exam: five-Pace Guide

As you study for the exam, follow the v steps below to ensure your AP Bio review is equally thorough and constructive as possible.

Step 1: Have a Diagnostic Exam

The first stride of your AP Biology review is to take a practice exam then you can run across how much y'all'll need to study and which areas need the most piece of work.

You should take your commencement complete practise test no later than the beginning of your 2nd semester. You can use a practise exam from a review volume or search online for a practice exam. The review books I mentioned in the previous section take some useful materials.

When you lot have a practise test, make sure it's the newest 2022 version of the exam (or, if y'all can't find this, at least a version from 2013-2019). If you run across exercise tests that accept 100 multiple-option questions in the first section, you lot're looking at a very old version of the AP Bio exam! You won't be able to rely on your scores on this version to become a clear motion picture of where you fall on the new exam.

Step ii: Calculate Your Score and Set up a Goal

One time y'all've taken a diagnostic test, y'all can calculate your score on the 1-5 AP calibration. According to the CliffsNotes review book mentioned to a higher place, you can guess your score using the following method:

  • Multiply the number of questions you answered correctly in Department 1 by 0.725
  • Multiply the number of points you earned in Section 2 by 1.25
  • Add those 2 numbers together to go your raw score

Then, convert the raw score to an AP score using the following chart:

Raw Composite Score

AP Score

60-100 v
50-59 4
41-49 3
33-40 2
0-32 one

For example, if you got 42 questions correct on the multiple-choice section and earned 25 points on the costless-response section, your raw score would be (42 * .725) + (25 * ane.25) = 61.7 = just barely made it into the v category!

This is without taking the bend into account, which is dissimilar every year, just it should requite you a rough idea of where yous stand. Unless you're scoring a really high 5 (90+), you should still put in a bit of study fourth dimension to brand sure y'all're fully prepared.

If yous score depression (1 or 2), you lot might make it your goal to raise your score to 3. Just keep in listen that some schools don't accept 3s for higher credit, so you might want to aim higher later on you make it to this first milestone.

Most colleges consider 4 to be the standard cutoff for AP credit, so you should try for at least a 4 if yous're hoping to get a head start in college. Once you're consistently scoring in the 3 range on this exam, you can set four or 5 equally your goal.

Even if you're already at the 4 or 5 level on AP Biological science, you probably still have some room to improve. It's nice to get in some actress practice so that you feel very comfortable on the real test.

Depending on how much you need to amend and on how long yous desire to spread out your prep, y'all might come up with different plans. To better by ane AP score point, you can get away with studying only two months or and so in advance. On the other mitt, if you're hoping to better by 2 or more than points, attempt to start midway through the school year to avoid cramming.

body_confidence-1.jpg Confidence is central. If yous demand to clothing a business suit to the exam to brand yourself feel in control, go for it (I am not responsible for the relentless mocking you volition endure from your peers).

Pace iii: Analyze Your Mistakes

This is the most critical part of the review procedure, and it'south particularly important for AP Biological science. In that location's a lot of material to learn, and you lot don't want to waste whatever time going over concepts you already have downwards.

Rummage through your mistakes on the diagnostic test to see where the most errors happened and why. Did your mistakes center more around lack of cognition of background information or difficulty analyzing the scenarios presented on the test (in other words, y'all knew the information but couldn't answer the question because information technology confused y'all)?

You'll well-nigh likely have a little of each blazon of mistake, only if one is more prevalent than the other, have that into account for your studying strategy. For example, information technology wouldn't be a good thought to continue drilling basic content cognition if near of your mistakes were due to your misinterpreting circuitous questions or reading diagrams incorrectly. You'd desire to devote less of your time to reviewing biological terms and more to doing realistic practice questions.

Even in those cases, you'll probably nevertheless accept at to the lowest degree a few issues with content knowledge. Every bit you get through your mistakes, keep a running list of the ideas you need to revisit in your notes or review book. If you're defenseless off guard by your unfamiliarity with a sure topic, you should pay special attention to that topic in your prep.

You lot might also detect mistakes due to carelessness or time pressure that aren't directly related to your knowledge of the material or understanding of the question. In this case, you'll need to think about revising your basic test-taking strategies. I'll get into more particular on this next.

body_detective-1.png Practise some practice exam detective work! I think this is a detective. Either that or a random guy smoking a pipe and trying to figure out how bad the pimple on his nose looks.

Step 4: Fix Your Mistakes

There are a few things yous tin can do to revise your strategies for taking the exam and effectively review concepts yous didn't understand.

The obvious start pace is to become back into your textbook, your notes, or a reliable AP Bio review book (or even all three!) and brush upward on the information you forgot. Sometimes for biology, this can be a lilliputian overwhelming due to the complexity of the material.

If you're trying to empathise systems or processes, I recommend testing yourself by drawing diagrams of how they work. This volition allow you to brand connections between dry facts presented in the text and the biological reality of what'due south happening in the system. It will help yous not only in your content knowledge but also in your ability to analyze related scenarios on the test. You can use this strategy for many concepts in AP Biology, and information technology will brand them much simpler to empathize.

To correct your other mistakes that have more than to do with question comprehension, you lot'll demand to focus on doing similar practice questions. I suggest getting Sterling's AP Biology Practice Questions for some questions that are organized logically by topic expanse and well aligned with the new test format.

More practice is too a good remedy for careless errors and time-management problems. You lot can learn how to better identify the cardinal parts of each question and avoid distractions that might throw you off.

Underlining the most important parts of the question tin can be a skilful strategy if yous're prone to devil-may-care errors. If time direction is a trouble, put some thought into why you might've run out of fourth dimension. Did you linger for too long on difficult questions? Remember that it'south a smart idea to skip questions that are giving you a lot of trouble (meaning, they're not answerable within a minute) and come dorsum to them later once yous've gotten through the whole section.

body_practice-10.jpg Practice makes perfect. Possibly you can etch an AP Biological science song to help you remember stuff. "Now enzymes ... Break IT Downward!"

Step 5: Have Some other Test and Echo Previous Steps

Now that you've analyzed and fixed your mistakes on the diagnostic test and done more targeted studying, information technology'south time to take another practice test.

Score this new test and and so repeat steps three and iv. Yous should notice improvements as you go along to echo this process and gain familiarity with the format and content of the AP Biology exam.

If y'all don't detect positive changes from one examination to the side by side, it might be time to reevaluate your review techniques. Depending on how early y'all start studying for the AP Bio examination and how much y'all want to improve, you might go through these steps once, twice, or seven times.

Continue the process until y'all achieve your score goals or run out of study time!

Conclusion: AP Biology Review Guide

The AP Biology test is a long exam, and it covers a broad range of material.

Recently, the test was updated to focus less on data think and more on analytical thinking, which can be good and bad. On the one hand, you won't have to rely on memorization equally much. On the other, your AP score will be highly dependent on your ability to think through complicated scenarios presented on the test.

In addition, the exam underwent some structural changes in 2020. These key changes included going from 69 questions on the multiple-choice section to only lx questions and reducing the number of brusk-reply questions from 6 to four. There will also no longer be whatsoever grid-in questions.

In your own AP Biology review, you lot should get over all the information you learned in the class. Withal, you should also devote a significant amount of your time to exercise testing and then that you tin can larn to think in the way the exam wants you to think.

If you plan your study fourth dimension wisely and learn how to solve the types of questions that are nigh hard for yous, you'll be on your way to a great AP Bio score!
