AP Biology Free Response Questions (FRQ) – Past Prompts

Hardy-Weinberg is one of the easiest mathematical operations to understand in AP Biology. While it may seem daunting at first, you'll soon realize that it is as easy as basic math, but is important to get a 5 on your AP exam! Check out the 

 now offered by Fiveable to continue learning and preparing for your exam!

What is the Hardy-Weinberg Principle?  🤔


The Hardy-Weinberg principle describes the characteristics of a population that is stable over time. In other words, the allele frequencies do not change from generation to generation. In order for a population to be stable and in Hardy-Weinberg Equilibrium, five conditions must be met: 

The population must be isolated from other populations.

There must be no mutations in the population.

Why Do We Use Hardy-Weinberg? 🤷‍♀️ 🤷‍♂️


The Hardy-Weinberg equation is important because it enables us to calculate the frequencies of alleles in a population. Scientists use the letter p to stand for the dominant allele and the letter q to stand for the recessive allele. The equation for Hardy-Weinberg is:

The basis of this equation is a monohybrid cross (Tt x Tt):

video on Mendelian and Non-Mendelian Genetics

How Do We Use the Hardy-Weinberg Equation? 🖊 📚


The Hardy-Weinberg equation is fairly easy to use if you are given the right information. To demonstrate how to use the equation, we will go through a sample problem.


If 9% of the population has blue eyes, what percent of the population is hybrid for brown eyes? Homozygous for blue eyes? 

The first step in these problems should always be to identify what information is given and what you need to find. In this problem, we are given the percent of the population with blue eyes (q^2). We need to find the percent of the population that is hybrid for brown eyes (2pq) and homozygous for blue eyes (p^2).

Now that we have our starting point, let's fill in the remaining variables we don't know. Because q^2 = 0.09, we know that q = √0.09 = 0.3 . From there we can find p because p + q = 1. So p = 0.7 and p^2 = 0.49. Lastly, 2pq = 2(0.3)(0.7) = 0.42.

Now all we have to do is convert our answers to percentages. The percent of the population that is hybrid for brown eyes is 42% because 2pq = 0.42. The percent of the population that is homozygous for blue eyes is 49% because p^2 = 0.49. 

As you can see, using and understanding Hardy-Weinberg doesn't have to be confusing. If you are ever confused, consider talking to your teacher or chatting with us here at 

. By following the simple steps provided, you'll be a Hardy-Weinberg expert in no time!

How Do You Use Hardy-Weinberg?

AP Bio at a first glance might seem to be all about memorization and knowing the vocabulary for each unit, but it is actually more than that. Biology is also about gaining an understanding of what comprises the building blocks of life and the processes associated with it from cellular respiration to DNA translation into RNA. By knowing the key points to focus on, however, you'll surely snatch that 5 and learn to appreciate the class as a whole.

: Identify what makes each of the four groups of macromolecules similar or different from each other. This will help you understand later concepts such as the plasma membrane and DNA!

Introduction to Biological Macromolecules

Structure and Function of Biological Macromolecules

🧬 Unit 2: Cell Structure and Function 

: Familiarize yourself with the function of most, if not all, cell organelles by using analogies to real-life scenarios and mnemonic devices!

: Use flashcards to highlight the major steps of cellular respiration and photosynthesis, the key players involved, and the byproducts of each process. It's easy to confuse NADPH with NADP+!

🦠️ Unit 4: Cell Communication and Cell Cycle

: Remember the acronym PMAT for the order of events of mitosis when it comes to the cell cycle and be sure to be able to name key events in each phase. Signal transduction and cell communication provide additional background on the technicalities behind various intracellular processes that could be asked on the exam.

: Practice your Punnett Squares and do lots of practice problems! Many students make careless mistakes because they gloss over them due to its seemingly easy-to-set-up nature.

👻 Unit 6: Gene Expression and Regulation

: Do a quick refresher on the differences between DNA and RNA before making flashcards for the steps of DNA replication, transcription, and translation. Don't confuse those three processes with each other!

Learning Objective: Describe the Fluid Mosaic Model of cell membranes

In every plasma membrane lies a structural framework of different components with significant cellular functions, making up a mosaic known as the 

. According to this model, the cell membrane represents a fluid structure comprised of proteins within a phospholipid bilayer. Ever since two scientists, S. J. Singer and and G. Nicolson, proposed this accepted theory about the membrane, the complexities behind fluid mosaic model still encapsulate ever-expanding topics of research to this day. 

Embedded within the hydrophobic interior of the plasma membrane’s lipid bilayer are 

. A heavy majority of these are known as transmembrane proteins, which cross through the entirety of the membrane一both the core of hydrophobic tails and exterior of hydrophilic heads. However, in some cases, other types of integral proteins only span partially into the phospholipid bilayer. 

In terms of the composition of an integral protein, there consists of different features that distinguishes its hydrophobic from its hydrophilic parts. Within an integral protein’s 

 areas (which lack an affinity for water), there are different polypeptide chains of nonpolar amino acids. These stretches of amino acids are normally coiled into alpha-helical structures, each of which comprise of hydrogen bonds. As for an integral protein’s 

 parts (which have an affinity for water), these regions have exposure to the extracellular aqueous fluid surrounding the cell’s membrane.

The other notable protein within the fluid mosaic model is known as the 

. These biological molecules, unlike integral proteins, do not extend into the hydrophobic interior of the plasma membrane. Though they may have exposure to regions of integral proteins, peripheral proteins are loosely attached to the phospholipid bilayer rather than embedded. 

Live Stream Replay: Membrane Permeability

Proteins have specific functions that contribute to the plasma membrane’s ability to sustain the cell’s internal and external environment. One of its primary specializations is the 

 of molecules both towards and against its concentration gradient. For instance, proteins can act as hydrophilic channels, which allow specific substances (that cannot diffuse through the hydrophobic cores) to pass the membrane. Other proteins, known as carrier proteins, can change their shape bring proteins to the other side of the membrane.

Proteins within the plasma membrane often function as 

, which aid in the speeding up of chemical reactions for specific substances. Because an enzyme’s its active site in the membrane is exposed to an aqueous solution, it can gain the ability to perform essential metabolic processes for the cell.

Along with their role in enzymatic activity, membrane proteins serve as primary sources of connection between other vital components of the cell. For instance, proteins embedded in the membrane can attach to parts of the 

, including microfilaments. Not only would this enable for the sustenance of a functional cell shape, but it would aid in the stabilization of these proteins within their designated location as well. In addition, some membrane proteins hold the ability to bind to molecules of the 

, enhancing the cell’s ability to regulate activities on both the extracellular and intracellular level.

, represents a role that the membrane proteins of neighboring cells can carry out. During this process, the proteins can attach to one another in the form of different junctions. Such can including gap junctions, which enable for cell communication through cytoplasmic channels, along with tight junctions, which prevent extracellular fluid from leaking due to its closely packed nature. 

 encapsulates a significant function that enables messages to be sent to the cell, inciting a specific response that regulates a certain activity. Within this process, a membrane protein can represent a receptor, which has a binding site shaped in a particular manner. This specific shape fits together with an external signaling molecule, known as a ligand, of a certain shape as well. As the binding between the receptor protein and the chemical messenger occurs, the protein itself may alter in shape, resulting in the communication of the message to the cell and a final cellular response.

Not only do proteins contribute to the essential functions of the cell membrane, but 

 hold an integral role within the fluid mosaic model as well. Carbohydrates play a major hand in 

, which involves one cell’s capability within pinpointing a one cell versus another different cell. Many molecules on the plasma membrane side that faces the extracellular fluid comprise of these carbohydrates, enabling cells to bind to these molecules to help detect other cells.

Membrane carbohydrates hold the ability to bond with different molecules, including both glycolipids and glycoproteins. Some of these carbohydrates, which normally possess no more than 15 grams of sugar, form lipid covalent bonds, and eventually create new molecules called 

. The majority of membrane carbohydrates, however, attach to proteins in the form of covalent bonds, creating 

In addition to proteins and carbohydrates, steroids represent cellular components that are essential to the regulation of the cell membrane’s activity. Most notably, located in between the gaps of hydrophobic phospholipid tails is 

, a steroid vital to controlling the fluidity of the membrane. Depending on the temperature of the environment surrounding the cell, these steroids play a certain role to sustain a fluidity necessary for proper cellular functionality.

When a cell is located in an environment of a high temperature, there is expected to be increased movement (kinetic energy) throughout the hydrocarbon tails of the phospholipid bilayer. However, cholesterol molecules serve to counteract this by restricting this movement of the tails. Within the human body, especially due to its high internal temperature of 37 degrees Celsius, the steroid cholesterol stops the presence of too much fluidity in the cell’s phospholipid bilayers.

On the other hand, cholesterol also serves to prevent the detrimental solidification of the cell’s membrane. If the phospholipid bilayer of a cell were to solidify, the permeability of the membrane, along with the activity of its enzymes would drastically decrease. Therefore, by preventing the phospholipid tails from closely packing, the cholesterol helps lower the temperature necessary for the cell membrane to solidify.

Study Guide: Properties of Biological Macromolecules

With its various molecular components, one could say that the fluid mosaic model encapsulates a tapestry of integral team players. The mosaic, comprising of different proteins with specialized functions, is vital to maintaining a functional environment on both the extracellular and cytoplasmic sides of the plasma membrane. Not only do proteins hold ownership of significant cellular roles, but components such as cholesterol and carbohydrates do as well.

Though a vast realm of knowledge of the fluid mosaic model has already been uncovered, the model’s extensive intricacies represent a constantly expanding topic of research today.

The sequence and make up of all molecules determine the property of that molecule.

Water is a unique molecule that is polar due to an unequal distribution of charge. The properties of water and essential to the existence of life on earth.

Water is able to form hydrogen bonds with other water molecules due to its polarity, and this contributes to the properties of cohesion, adhesion, and surface tension.

The elements of life are organized on the periodic table.

The elements most common to biological molecules are carbon, nitrogen, hydrogen, oxygen, and phosphorus.

Amino acids may be polar, nonpolar, sulfur-containing, acidic, or basic. The function of a protein depends on what amino acids make up a protein.

The order of nucleotides in DNA make up its genetic code. DNA is antiparallel, forms a double helix, and contains hydrogen bonds between nucleotides.

Lipids are nonpolar and hydrophobic. The presence of double bonds in lipids contributes to whether or not it is a saturated or unsaturated fat and contributes to its function.

Carbohydrates are broken down to make energy. The complexity of the carbohydrate structure determines the amount of energy needed to break it down.

DNA and RNA are similar structures with the exceptions of a few key differences.

AP Biology Unit 1 Review - Chemistry of Life

 I'm an AP Biology teacher from Chicago, IL and streamer at Fiveable. This year's exam is different than we expected, but I'm here to help. I've put together this study guide to help keep you on track while you are studying from home. You can 

follow this guide on your own with a free Fiveable account

! I'll also be joining a group of students live on Mondays @ 8pm ET during cram sessions. 

This year, the AP Biology will look different than you were expecting. As we’re all on quarantine 😷 due to COVID-19, the College Board has decided to update the format and content of the test to fit an online testing format.

You’ll have 45-minutes to take the exam online and it will only cover units 1-6. If you have already studied content from unit 7 or 8 don’t stress! It’s all worth knowing.

These units are on the exam. Click the unit to see the study guide!

7 - 🦍 Natural Selection
8 - 🌲 Ecology

As of March 20th, we know the test will ONLY include free-response questions and no multiple-choice questions. However, we don’t know yet exactly what this will look like. 

 Wherever you are in the world, this is the time you’ll take the test. Unless you have been approved for the make-up date in June, but only your school can request that. You’ll take the test online. There will be a practice simulation posted by College Board within the next few weeks.

With so many school closures and the stress of a global pandemic, this review season will be different than usual. If this is your first AP exam, welcome! Don’t worry, it’s not usually this chaotic. 

We’ve put together this plan for you to follow between now and May. This will cover all of the units and leave you time to practice questions before test day. Some classes may have done units out of chronological order throughout the year, which is ok. The units don’t have to be taught in order. If you are learning new material on your own and need some help, use the chat bubble on 

. We’ll answer any questions you may have. 

All of the required resources are free, including cheat sheet PDFs. 

  We’ve also linked a few other websites, articles, and YouTube videos that you can access for free. Some of the suggested resources include paid products. There are some documentaries that you can find on streaming sites with a paid membership and we’ll also list streams and practice questions that require a paid cram pass on Fiveable.

Before we begin, take some time to get organized. Remote learning can be great, but it also means you’ll need to hold yourself accountable more than usual. 


Make sure you have a designated place at home to study. Somewhere you can keep all of your materials, where you can focus on learning, and where you are comfortable. Spend some time prepping the space with everything you need and you can even let others in the family know that this is your study space. 

Get your notebook, textbook, prep books, or whatever other physical materials you have. Download the AP Biology 1-page cheat sheet from our collection of 

. Also create a space for you to keep track of review. Start a new section in your notebook to take notes or start a Google Doc to keep track of your notes. Get your self set up!

The hardest part about studying from home is sticking to a routine. Decide on one hour every day that you can dedicate to studying. This can be any time of the day, whatever works best for you. Set a timer on your phone for that time and really try to stick to it. The routine will help you stay on track.

How will you hold yourself accountable to this study plan? You may or may not have a teacher or rules set up to help you stay on track, so you need to set some for yourself. First set your goal. This could be studying for x number of hours or getting through a unit. Then, create a reward for yourself. If you reach your goal, then x. This will help stay focused!

Unit 1 introduces all chemistry concepts that need to be applied to biological principles. The key elements are named, macromolecules are defined, and the characteristics of the chemical contribution to life are laid out. The content in this unit can be a bit dry, with a focus on vocabulary and more detailed chemical applications than are seen in other aspects of the course. A lot of processes discussed in later units depend on a strong understanding of this unit.

If you have more time or want to dig deeper:

AP Bio New Format (FRQ) Study Guide

AP Biology can be a daunting class to walk into. With just 7 to 8 months to learn everything from ecology to DNA and RNA, you might be questioning whether you are ready to take such a challenging class. While AP Bio is one of the hardest AP subjects, you can use these tips to learn what you’ll need to know before taking AP Bio and you’ll be able to walk into your class with confidence.


Don’t let the amount of material overwhelm you

While there is a lot to cover, most ideas have connections and ways to easily understand topics. To help you better make those connections, AP Bio is broken down into 4 main ideas:

: The process of evolution drives the diversity and unity of life.

: Biological systems utilize free energy and molecular building blocks to grow, to reproduce and to maintain dynamic homeostasis.

: Living systems store, retrieve, transmit and respond to information essential to life processes.

: Biological systems interact, and these systems and their interactions possess complex properties.

Being able to think of biology in terms of these 4 Big Ideas will allow you to put more nuanced and descriptive terminology into perspective.

Make connections instead of memorizing content

When it comes to AP Bio, it’s best to know about connections rather than specific terms. AP Bio is NOT memorization. In fact, if you just try to memorize terms and concepts, you’ll have a much harder time keeping track of everything you need to know. Memorizing as a strategy is not ideal for any AP exam because it is way harder to answer the essays. If the exam was just straight trivial multiple choice, then memorizing would help. However, so much of your score will rely on your ability to analyze, evaluate, and make connections. Even the multiple choice has been updated to reflect this as a goal from College Board.

When learning about complex topics that you might not be familiar with, focus more on the relationships rather than the terms and definitions. Most importantly, try to connect ideas to the four big ideas mentioned earlier. You can use tools like mind maps to help you make connections. Then, when you are stuck trying to answer a question, try to visualize the connections you made. Seriously, this is one of the best study strategies for any AP exam.

By the end of the school year, you’ll be able to understand any complex AP Bio processes because of the network of relationships you learned throughout the year.

When it comes to topics like ecology and evolution, common sense and logic are really all you need. While you will need to know some terms for these sections of the exam, most problems you will be presented with will be solved logically. On the AP Exam, you will be presented with a large amount of information to help you answer the questions. While you will be able to answer the questions with your knowledge of biology, logic and common sense can also be used to answer the questions effectively. Here’s an example of when logic can help you:

Let’s say there are populations of wolves and deer on an island; there is a predator-prey relationship between them. If the wolves are the predators and the population of wolves increases, it can be assumed that the number of deer will decrease because the wolves as a pack will consume more deer.

As you can see, logic can be your best friend when it comes to AP Biology.

AP Biology is one of many AP classes that require a large amount of reading. One of the most things to remember for AP Bio is that you cannot fall behind on reading. Reading your textbook throughout the year is a necessity. By keeping up with your reading, you’ll be able to understand complex ideas with ease. While reading an AP Bio textbook filled to the brim with facts might not sound like the most appealing way to spend your time, it will definitely pay off in the end.

In addition to your textbook, you can use your teachers as a resource. Find out if your teacher has office hours or extra time between classes. Teachers can help you better understand material and they will be happy to help.
