AP Biology Exam

Well in today’s post I will be reflecting on my AP Biology Exam, or rather… the part of it I took. I could not make the original AP Biology exam that the rest of the class took because I was on an airplane ride home from Louisville, Kentucky. Therefore I was scheduled to take my exam on Friday the 19th! However… things did not go as planned.


I went in that morning bright and early and sat in Ms. Cerles office. She read me all the instructions, and just as I was about to begin, I noticed that the front page said that if the test was being administered to me anytime before 12 pm, to immediately stop. Being that it was 8 am, I questioned this. Ms. Cerles called Mrs. Cunha who said all should be fine and I went ahead with my test. As I am on one of the last questions and over an hour has passed, Mrs. Cunha bursts in the room talking on the phone needing my student ID immediately saying that I must stop the exam. She later comes back to tell me that she was speaking to college board and they said that my exam needed to be canceled since I was taking it at the wrong time and that I would have to reschedule. I also needed to write a hand written note saying I would not speak about the testing material. Then, I went back to AP Bio class.

I am not upset at all. To be quite honest, I did not expect to pass the AP Biology exam in the first place, and I wasn’t too keen on taking it in the first place. Sure, I am slightly annoyed that now I have to go through another multiple choice section of AP Bio (because to be honest, I dozed off a couple of times during the test) but in the scheme of things, its whatever. I am not upset with Mrs. Cunha or Ms. Cerles because it was an honest mistake! Now I have more time to study, if I so choose to do so. The part of the test I did take was not at all as hard as I expected it to be! But I am not getting my hopes up. I am taking my new test this friday so let’s hope I do well!

Let’s Talk About Biases

Confirmation Bias (noun): The tendency to interpret new evidence as confirmation of one’s existing beliefs or theories.

Picture this…you’re arguing with someone and backing your statements with facts, however, the other person refuses to see it your way. I’m sure we have all experienced this, and it has driven many of us crazy. Their refusal to see it your way is likely because of confirmation bias which causes many people flat out ignore or disregard information that conflicts with their opinion. To get past this, the first step is realizing that we all have a bias regarding our own opinions and that we may not understand everything as well as we think we do! In this post, I am going to do the #DoNowConfirmationBias from KQED. This do now asks me to pick a controversial topic and research what the other side believes and why they believe this! The topic I have chosen is animal testing! I support animal testing because it has led to so many lifesaving medical cures and treatments, the animals are treated humanely by law, and there are no other real alternatives, to name a few reasons. But let’s get into why people are against animal testing. Warning: this blog post may contain graphic images.

  1. There is data suggesting that animal testing is actually cruel and inhumane. In 2010 the US Department of Agriculture reported that 97,123 animals have suffered pain with no anesthesia during experiments. For example, the Draize eye test (used by cosmetics companies) is done to test irritability caused by shampoos and other products, however, this test requires rabbits to be kept with their eyelids held open by clips (sometimes for days on end) so that they cannot blink. ouch

    The stock rabbits are kept in to prevent them from moving or cleaning out their eye
  2. Alternative testing methods exist, thus we can replace animal testing. In glass testing is known as in vitro testing which is where cells cultures in a petri dish are studied using human cells. Also, microdosing is a form of testing where small doses are given to human volunteers (doses too small to cause bad reactions) and then their blood is analyzed. Instead of testing chemicals on rabbits skin, researchers can use artificial human skin. And these are just three examples!

    In Vitro testing
  3. Animal testing does not predict reliable results in humans! Data shows that a whopping 94% of drugs that pass animal testing fail when given to humans in clinical trials.
  4. Animal testing is VERY expensive. Humane Society International discovered that an “unscheduled DNA synthesis” animal test costs $32,000 compared to the in vitro alternative which costs $11,000. It is also important to note the US National Institutes of Health (NIH) spends $14 billion of its $31 billion annual budget on animal research!
  5. Being that animals can suffer in the way humans do, it is speciesism to experiment on them. People opposed to animal testing often argue that just because animals lack the cognitive ability, language and moral judgment that humans have, does not mean they can be tested on. They often equate this to testing on humans with sever mental impairments, which we know is not right. An english philospher Jeremey Bentham once said,

The question is not, Can they reason? Nor, Can they talk? but Can they suffer?


These are just five of the reasons why many people are against animal testing, and I encourage you to look into it for yourself and reevaluate your own opinion. I still believe that despite these cons, animal testing is beneficial, but my beliefs have been challenged and I now have more appreciation for the cures and treatments that successfully come out of animal testing.

Wolbachia Lab!

Purpose: The purpose of this lab was to determine how many of the collected Bay Area insects have the Wolbachia bacteria in their DNA


  1. What is Wolbachia?
    1. Wolbachia is a bacteria infecting arthropods and nematode worms that can change the sex of the host as well as kill their offspring
  2. Why is Wolbachia being studied? What did you discover in your research?
    1. Studies have shown that Wolbachia can be used to stop the mosquitos that spread diseases like zika and dengue and also finding ways to end this virus can be useful in curing diseases like Lymphatic filariasis (elephantiasis) and Onchocerciasis (river blindness.)
  3. What kinds of relationships does Wolbachia have with other organisms?
    1. Wolbachia is parasitic to other organisms as this bacteria benefits at the expense of the other organism Specifically, Wolbachia is an endosymbiotic parasite which means that it lives inside the host cell.

I was going to list out all the steps, but that would be a very long list! So, instead, I will summarize. First, we all brought in bugs from our houses or our surrounding areas and froze them in alcohol. Next, we mashed up the abdomen of the bug, and if your bug was a certain size, you had to cut it to make sure you just get the reproductive parts of the insect! I needed to cut mine because I caught (my dad caught) a moth and this bug was pretty big! After the abdomen was all smushed in our microfuge tubes, we had to separate the DNA from the pellet (the stuff we do not need). We did this by centrifuging many times and adding different liquids like NaCl and Lysis Buffer which bind together to give us a clear DNA sample. After going through multiple steps, it was time for the Polymerase Chain Reaction (PCR) machine which replicates the DNA thus allowing the electrophoresis gels to be clear. Also on the gel electrophoresis, we included a positive control and a ladder both of which help us determine what is DNA and what is Wolbachia so thus we know whether or not the insect had been infected with Wolbachia bacteria.


Personally, my moth was not infected by Wolbachia and had a visible DNA on the gel! Out of the 11 girls who performed this experiment, there were only 4 insects infected with Wolbachia and all of them came from the Redwood city/ San Carlos area. A coincidence? I think not.


The experience of this lab was much easier and more fun than the other labs because I was more prepared being that I understand the topic and work more. Maybe it was the fact that this was my last lab and I had all the knowledge of my other labs in the back of my mind, or maybe I was just less stressed. Regardless, this was definitely my favorite lab being that I 100% understand what was going on. I understood all the tools we were using like the centrifuge and electrophoreses, even though occasionally I had micropipette troubles.

AP Bio Rockstars part 2!

In this AP Bio Rockstars round up, I am going to be telling you about the classes from May 7th to May 21st! In this time frame, we had a lot of fun, even if not everyone was present at all times! The class had some buggy visitors, we discussed Henrietta Lacks and her cells, we had a Wolbachia lab, and now we are working on our digital sites!

Although I was absent for the Arthropod visitors, my fellow classmates Natalie and Keira all had amazing blog posts about them that I will link at the bottom! Natalie blogged about a Lubber grasshopper which was the “sickest looking arthropod” she had seen all day! From her post, I learned that this little bugger is a vegetarian and that they bury their eggs in a sandy place for protection.

Natalie also posted about a Madagascar Cockroach, which is apparently very important to the food web because these arthropods can eat anything, and are also a food supply for others.

Keira is seen below holding a Giant African Millipede which is very fragile! This millipede can grow to have about 300 legs and live to be 20 years old! However, they only live this long assuming they do not get eaten by other organisms! I can tell you this much…if I saw this certain arthropod in my house (or anywhere for that matter), my two legs would carry me very far away and very fast.

Keira also posted about her favorite creature of the day, the Whip Scorpion which has eight legs and one is super long which is known as the whip! From Keira’s post I learned that this arthropod has olfactory receptors thus allowing the organism to smell, in fact, they smell with their legs!

We also watched the Henrietta Lacks movie and blogged about it! Basically, Henrietta Lacks was a poor African-American woman whose cells were stolen from her without her knowledge and became known as the immortal HeLa cells. These cells have since been used for quite a lot in the medical and research field, yet her family was never compensated. Watch the trailer below, and the book is available as well!

We then started working on our Wolbachia lab this week, and get this, we all brought in bugs! THAT WE CAUGHT!!! Well my dad caught mine, but I digress. Wolbachia is a bacteria that infects arthropod insects and nematodes and feminizes them and kills their offspring. We collected DNA from our little buggies and when we get back to class we will be seeing our results!!

Finally we will be working on our sites quite a lot. We posted videos giving advice to the future ap bio girls, and we have many blog posts to write preparing for the end of class!! 11 days until graduation, the end is near and the journey has been great!

A Reflection on The Immortal Life of Henrietta Lacks


Henrietta Lacks

To begin, let’s go over the basics. Henrietta Lacks was a poor African-American woman of the 1920s who was diagnosed with cervical cancer at 31 years old. Cells from her tumor, known as HeLa cells, were taken without her consent and were discovered by researcher George Gey to grow and divide without limit thus making them “immortal.” This had a giant impact on the science and medical community, one that you most likely have benefitted from. The HeLa cells have been used to create the polio vaccine, aid in the understanding of cancer, cells, and HIV/AIDS, have been exposed to nuclear testing and toxins, have been to space, and are currently being used to grow viruses and test antitumor medicines. To put it shortly, the HeLa cells have done quite a lot! But for all this work… her family was left in the dark and they were not paid even a dime.

The book, The Immortal Life of Henrietta Lacks by Rebecca Skloot details how Henrietta’s daughter Deborah and the author Rebecca journey through understanding HeLa and Henrietta, as well as provides the reader with information about Henrietta’s life as a whole. What is important to note is that this most definitely is a race issue. Henrietta Lacks was mistreated by John Hopkins, mistreated by George Gey, mistreated by the companies that gained millions of dollars of her cells and the Lacks family is STILL mistreated as they have YET to receive compensation. The 1950s were not a pretty time racially, yes that I can admit. But there is no excuse as to why they have yet to be paid. Not one.

The novel by Rebecca Skloot

Reflecting on this makes me question my own beliefs, as I most definitely want to either go into medicine or into research, two key topics here. As a doctor, it would be my job to look after my patient with no bias, no matter what color, size, income, history, etc. As a researcher, I would need to equally understand that the end does not justify the means.

There is NO excuse for unethical behavior, even if the outcome is stupendous.

Can you imagine having such a large impact on the world and your family never knowing or receiving any benefits? That would be like Bill Gates, Steve Jobs, Mark Zuckerberg, Stephen Hawking and many more names I am sure we all recognize never being acknowledged for their contributions to society. But reading those names and matching them to faces… we all know the differences between them and Henrietta Lacks. I challenge you to look within yourself and determine whether or not something like this could happen today. Personally? I am absolutely positive it could. We have fixed a lot as a country in regards to racial issues but we still have so far to go.

I encourage you to read this book, you can get it on your apple device for $10.99 or in your nearest library! Or you can watch the movie, produced by HBO, which I will link below.


LiMPETS Field Trip

This Wednesday, my classmates and I went on a super fun trip to the Pillar Point Marine Reserve in Half Moon Bay! LiMPETS, which stands for Long-term Monitoring Program and Experiential Training for Students, is a program that studies and collects data on California’s coastal ecosystems. On this field trip, we learned all about algae and invertebrates, and were able to not only see them but touch them as well! Admitably, I squealed a few times when touching these organisms, as you will see in the video. We learned how to collect data, how to identify organisms and we learned about the horrible sea star sickness that caused the area to go from having 45 sea stars 10 years ago to having zero less than 5 years ago, luckily we found 10 on this trip.  Watch the video below and leave feedback! Here is the LiMPETS website!



Save The Bay Reflection

Today our class went on an AMAZING  field trip to the Save The Bay site in Palo Alto. What is this organization, you may ask? Well based on their website (,

Save The Bay is the largest regional organization working to protect, restore and celebrate San Francisco Bay since 1961

This organization works to restore the area, protect from pollution as well as make it cleaner and healthier for people and wild life. The leaders who directed us today taught us much about the environment. I learned quite a lot, but to list some…

  1. Simpson’s Equation wpeFA.jpg (2544 bytes) determines how diverse an area is. This is done by looking at the number of individuals of a species also by looking at the number of different species. If your number is zero, this means the area only has one species. If your number is closer to one, then the area is more so biodiverse. However, a biodiversity score of one is virtually impossible being that this would indicate infinite diversity.
  2. Salinity levels are higher near the bottom of the hill as opposed to the top. This is because the bottom soil is affected by the large amounts of salt in the water while the top soil is not.
  3. Within the five tested areas, the soil texture greatly differed between clay-like, gritty, and smooth. Even though this dirt was only a few feet apart, these differences occurred partly because of the amount of water that directly affects the soil. The dirt near the water was more clay life and the dirt at the top was drier and more gritty. This is also because the plants affect and change the soil which then affects and changes the plants!

In class, we had been learning about Chi-Square statistics. This formula is as follows,chi-square statistic. and is another way for us to determine something based on our data and a set of numbers. Both of these equations look complex, but in reality, they are super simple once you understand what you are being asked to do! Also in class, we learned that sometimes experimental error can occur as we discussed in our previous lab. My group’s salinity data had one outlier that threw off our data, and we had to acknowledge that this could have possibly been a human error or a device error.

A memory I want to share is that eureka is California’s state motto which means,
“I have found it!” Mrs. Girard disclosed this information to me as we were discussing the state flower and the legality of picking it. The service learning aspect of the trip enabled me to not only learn with my hands, but it also made me proud of our class and the little ways in which we helped! Knowing we are part of aiding Bay area restoration, even in smaller ways. I quite honestly feel as though I would not change anything about the program, I had an amazing time but those who come after my class should wear many layers, running shoes or rain boots! Attire is crucial.

This field trip was truly awesome and the time sped by! The field ship should definitely be done again in the same location. This trip taught me a lot about the environment and much more.

I made a video, watch it below!

Pigs Being Used to Grow Human Organs?!

Recent research is testing whether or not human organs can be grown in pigs! Now, this may sound a little wild, however, this challenge to science is really quite interesting.

Let’s delve into this and how exactly these tests work. The process is completed in stages, with the first stage using CRISPR gene editing. This technique takes away the gene that codes for the growth of a specific pig organ. Human stem cells are then injected into the embryo which had the pig organ gene taken away. This is done with hopes that when the embryo is placed into a mother pig, the human organ would grow inside the embryo which could one day be removed and placed on a human transplant.

Now that we know the “how” let’s investigate the why. The American Transplant Foundation reports that 22 people die every day waiting for organ donations and those who remain alive as they wait often suffer deeply. The goal of this research is to save human lives so that the number of people who die while waiting for an organ to save them can be greatly, if not totally, reduced. Also, this project opens the possibility of using the organ recipient’s own stem cells as an injection into the embryo which would then end the need for the patient to take immune-suppressing drugs for the rest of their life, as their body will not reject an organ it sees as its’ own.

Why is anyone opposed? Well, there are a few reasons. There is a risk that the baby pigs could develop human-like brains. So far the tests have been cut off at a certain timeline, therefore, preventing this from happening. Another worry is that the pigs DNA could alter the injected DNA. Lastly, many question whether or not it is ethical to grow pigs solely for the need of an organ for a human.

Personally, I think the gain is bigger than the risk. We know for a fact that people are dying and suffering as they wait for their organs. We do not know for certain what could happen with the pig embryos, but if this new method can save lives, then I am all for it! Farms currently grow pigs to sell them as bacon, sausage and other various forms of meat. So why not use them to grow an organ, save a life, and then put them in a grocery store. Would that in itself cause another ethical question? Would people buy bacon made by a pig that also made a human organ? There are so many hypotheticals, but based on the facts, this could prove to be very beneficial.

Ghost in Your Genes Movie Review

I absolutely loved watching this movie, for a multitude of reasons!

  1. The movie did a GREAT job of hooking the viewer through suspenseful music, flickering images and intriguing questions.
  2. Twins run in my family, therefore there is a possibility that I may have them!
  3. I adore genetics and more so love puzzles like why twins with the exact same genome differ in diseases and disorders!

Building off of number 3, learning about epigenetics has only increased my love for the overall topic of genetic sciences as a whole! In Ghost in Your Genes, the scientists revealed that an epigenome is defined as above the genome, but in layman’s terms…

The software that tells the computer, how, where, and how much to do.

Basically, twins can have the exact same genome, however their epigenetics will switch different traits on and off. For example, twins A & B have different epigenetics, which is how twin B can have autism while twin A does not. Scientists also did tests which showcased that one’s epigenome can change based upon the nurture of their mother as shown by rats. This only adds to the large biological question of nature vs. nurture.

The choices one makes in life, the events that happen to them, and the way they are raised all affect their epigenome. People who sufer from traumatic childhoods often showcase similar mental effects, as seen in many serial killers. Science can explain why some people murder multiple people while people raised in the same circumstances do not. Which is also why I loved this movie because I have always wondered what creates a serial killer.

The last thing the movie covered was how scientists in Sweden were able to connect the affects of famine on the grandparents to their children. If a grandpa was effected by famine in his early childhood, then his grandson should live for an extended period of time. However if a grandma was effected by famine while she was in the womb, then her granddaughter will most likely die early. Small differences in the lives of the grandparent can change the life of their following generations.

All of this new information completely boggles my mind! Your outside life can effect what traits are turned on and off for you? The lives of your previous generations can affect your life today? Twins can be 100% the same and yet 100% different? This movie was short, fun, and amazingly scientific! if you have the opportunity to watch then I certainly recommend!
