Drug post HCE
Cocaine
Cocaine is a strong, addictive drug usually used recreationally.
It’s made from the leaves of the coco plant, ingested in powder form.
It has a lot of negative effects, including intense depression, edginess, high cravings, paranoia, increased heart rate, increased risk of stroke, heart attacks, seizures, and more short term and long term effects.
Native South Americans used to chew coca plants (the plant cocaine is produced from) because they thought it would protect them against diseases.
Genetic Mutation Story
Mutation story:
Part 1:
It was a normal day. I was just a gene, getting along with all of the other genes on our DNA strand. But, then, that day, my life was changed forever! The worst thing that could’ve happened to me, happened. It was every gene’s worst nightmare…I became a mutated gene! Basically, what happened was my DNA strand didn’t get copied properly, and I was the unlucky victim that this affected. The error in the DNA replication resulted in my deletion, meaning I didn’t exist on the DNA strand I was supposed to. The molecule RNA was supposed to copy all of the information off of my DNA strand, but thanks to its mistake I was left behind. But what I forgot to mention was that I was the most important gene-I was a DMD gene. My job would have been to make specific instructions for a protein called dystrophin, which helps stabilize muscle fibers. So since I couldn’t leave the nucleus, I really couldn’t help my host in any way, and they lacked the dystrophin that their body needs.
This mistake didn’t leave a good impact on my host, sadly. I was a negative mutation. My mutation caused him to fall very often, to be very clumsy, for his calf muscles to be enlarged, difficulty to stand up. I put him at risk for cardiomyopathy, and made his lungs weaker. He has weak thighs, weak stomach muscles, and a swayed back. All of this was a result of him lacking dystrophin, so his muscles didn’t work like they should have.
This made his life different. By age 12, he was put in a wheelchair because his muscles just weren’t doing well enough to support his weight. He’s 20 now, and at I’m really worried about him because there’s no treatment for Duchenne Muscular Dystrophy yet. But, he’s strong and I’m hoping he still has a lot of time left. The life expectancy for people like him is getting higher and higher! Some men live up to even 50, which is a lot more than the original expectancy was. My only hope is that he will live a good, full life and he won’t let my mutation stop him from doing great things.
Part 2:
My questions: How does a gene get deleted? How does a mutated gene cause DMD? What is DMD? What are the symptoms of DMD? What is the life expectancy for people with DMD? How does someone get DMD?
Mostly I used Google for this project, but a used a Youtube video as well.
My process was to first find out the general information about Muchenne Muscular Dystrophy, and then find out how it is caused, and then narrow it down to the actual gene mutation and how it is caused.
To cite information, I wrote down the names/links of any sources I used, and I knew most of them were credible because they were organization or government-run websites.
The process of completing it was kind of hard at first because there was so much information (some of which I didn’t understand), but the more I researched it the easier it became to sort out the info. Also, I found that using different sources helped because each site had the same information, just worded differently. What I could have done better was start earlier because I found that I was more stressed out because I did it later, and so if I started earlier maybe it would have been better quality work. Also, I would’ve specified some things with my teacher because I wasn’t clear on some aspects of the project.

Science app review
For this assignment, my questions were:
1. What is the best feature about this app?
2. How easy is it to understand?
3. Is it more educational or entertaining?
4. What does the app teach me?
5. What am I getting out of this app?
6. Can the things I learn in this app help me in my science 9 class?
7. What subject in science does the app address?
This app (elements-learn the periodic table) has no explanation before you start using it/playing the game, but it’s very simple and easy to figure out on your own. Basically it shows you the periodic table, with only one element highlighted. You can’t see any of the information about it, except for its atomic number. Based off of the atomic number and the placement of the element on the table, the user needs to guess which element it is. I 
think this could be very useful because it helps you memorize the placement and atomic numbers of the elements, in addition to learning what the element looks like as the game also includes a picture of the element to give you a visual if you need help figuring out the answer. I think the app’s best feature is that it’s very simple and straightforward, but yet still effective.
As shown in this picture, if you get the multiple choice answer wrong, it marks it as wrong and shows you what the correct answer is instead.
If you get it right you gain points and your percentage is raised.
I think I can definitely use the app to help me in science, because our unit right now is chemistry and the periodic table. Even though it doesn’t teach me anything new, using the app will help me memorize and get a better understanding of the elements and their place on the periodic table. I would recommend this app/game, elements, for anyone who needs to study the periodic table and the elements’ symbols and atomic numbers, as it really helped me review what I already knew about the elements and their location, symbol, atomic number, and their appearance.
