When you hear the word cancer you probably think of a terrible disease, which is very complicated and unknown, which is understandable. Common questions that people ask about cancer include: is it alive? Why aren’t Doctors able to find a single cure for it? Is It contagious?
The answer to the first question: is cancer alive? The answer to this is a little complicated because cancer is caused from cell mutations or cells that no longer do what they were designed to do. These mutated cells act out in the body like a virus, and are dependent on the body, which generally means that cancer is not alive.
Cancer is complex; there are many types of cancer. Cancer is a very broad term to describe a series of diseases. Because of this doctors have not been able to find a cure. Of course there are treatments for cancer, a common example of which is chemo.
But is cancer contagious? No. Cancer is not contagious, not in the way like a cold or any other contagious illness. This is because cancer is not alive, like I pointed out above. But you can inherit cancer through genetics, but I would say that this is not the same as being contagious.
In conclusion, cancer is not alive, incurable due to how many types of cancers there are, and not contagious.
Males have an X and a Y Chromosome, a female on the other hand has two X chromosomes. Color Blindness is an X linked trait, which makes it seen that women are far more likely to be colorblind, but statistically men are far more likely to be colorblind than women. Why is this the case?
Like I mentioned above color blindness is an X linked trait, but another thing about color blindness is the fact that it is a recessive gene, which means if a woman was to be color blind she must inherit this gene from both her mother and father. Women also can pass down the gene to her children. Men as I stated above statistically are far more likely to be colorblind, this is because they don’t have an extra X chromosome to cancel out the gene, which in turn means that if they inherit the color blind gene they most definitely will be color blind.
Hence, because females have X chromosomes, the only way for a woman to be colorblind is if both her parents have the colorblind gene. But because men don’t have an extra X chromosome if they inherit the gene they most definitely will colorblind.
When someone sneaks up behind you and shouts “Boo!” For a little bit your heart beats faster, even though you didn’t do any physical activity that would of course increase your heart beat. But what caused your heart to behave this way after being startled or surprised?
When I am startled my body becomes aware of a potential threat, or something that may potentially be dangerous for me. When my body is aware of this it releases certain chemicals and hormones which will put my body into the mode of “fight or flight.” The unique phenomena of “fight or flight,” heightens my senses, and is my body’s response on how to react to potential danger, by either “fighting,” or “running.”
In short, this is why your heart beats quickly when you are surprised/startled.
As most know all living things need some sort of energy to survive; and most also know that the sun provides a tremendous amount(much more than what is used), of energy to earth. But even with all of this available energy why do living creatures still have such a difficult time obtaining energy, and why do creatures still starve?
Well first of all I am not expert in this and this essay is only based on what I think is the answer(s) for the questions above. Also to note not all living things receive direct energy from the sun, for example a lot of living things actually get energy from other living things. So with those things on the clear here is the reason why I think living creatures have such a hard time obtaining energy, why living creatures still starve.
The reason I believe is the fact that in some areas there is a lack of wild plants(which are the primary producers). This is due to a variety of factors, including changes of climate, etc. Because of the lack of plants or primary producers the herbivores(primary consumers), will starve because they depend on plants for their energy. Because the primary consumers are starving off the secondary consumers or the carnivores will now have a shortage of their food or energy source. Hence why living creatures have such a difficult time obtaining energy.
In this week’s science essay I will be writing about three engineering fields that interest me. These fields are: Biomedical engineering, Chemical engineering, and Systems Engineering. I personally don’t want to become an engineer, but these three engineering fields I found very interesting.
Biomedical engineering is a type of engineering that applies to the human body. Usually Biomedical engineering is applied to the human body either as a medical or a beneficial way. This field of engineering uses engineering principles to Biology, or in other words the human body. Biomedical engineering is a good College course to take if you want to become a doctor; it is also a good field if you are very interested in Biology.
Chemical engineering is a type of engineering that creates chemicals, raw materials, living cells, energy, etc, into useful items. This type of engineering uses engineering principles of chemistry, physics, mathematics, biology, and even economics. This type of engineering is great if you like high level science such as chemistry and physics, along with math and economics.
Systems engineering is a type of engineering that focuses on how to design, integrate, and manage complex systems. This type of engineering requires math, economics, and even computer science. This type of engineering is great if you like computer science and economics.
These are three engineering fields that interest me.
In this week’s science essay I will be writing about Malware, or Malicious code. I will be getting into: what it is, how you can get it on your computer, and how to protect your computer from it.
What is Malware?
Malware is a malicious software or code. That changes the settings, delete your software, cause problems or errors, watch your browsing habits, or open your computer to attacks.
How Does Malware Get on Your Computer?
An example of a way that Malware can get on your computer is; say if you visited some website, and you get a download that you did not request, if you accidentally run this download, that is a way to get Malware on your computer. Another way is if the Malware software notices some weaknesses in your computer web browser it may install itself, without requiring you to download anything.
How Do You Protect Your Computer?
A way to protect your computer from Malware is by running a malware-cleaner, this will help ensure your computer’s safety.
In this science essay I will be writing about web browsers, and how they work. What I will be getting into in this essay is: how web browsers work, what are the popular web browsers, and the common error messages that you can find on a web browser.
How Do Web Browsers Work?
A web browser is used to connect the world wide web. Browsers are like indexes of the web, they contain millions of web pages that they organize. When you search something on a web browser, the browser will find the closest matches to your search, which they display. A lot of browsers will post sponsored content at the almost top or top of the search results page. Those results are usually similar to the thing you are looking for, and are paid by a minor party.
What Are the Popular Web Browsers?
The popular and most used web browsers are: Google Chrome, Mozilla Firefox, Internet Explorer, and Apple’s Safari. I personally use Google Chrome. But there are much more web browsers, that are less known and used.
The Common Error Messages You Can Find on a Web Browser
Sometimes you may come across an error message on your web browser. The two most common errors are:
503 service unavailable: this error means that the browser cannot contact the website.
404 not found: this error means that a page on a website was deleted or you typed an incorrect URL.
This is my essay on web browsers.
In this week’s essay I will be writing about Transistors: what they are, what are they used for, and how they are made.
What are they and what are they used for?
A Transistor simply is a very small electronic component that can do two jobs, a Transistor can also work as an amplifier or switch. A Transistor is very small and it weighs 0.000000000000000000000000000001 kilograms! Even though they are small they are very important and powerful.
When a Transistor works as an amplifier it takes a very small amount of electric current on one end, or an input current, which produces a larger electric current. When a Transistor works as a switch it takes a small electric current in one part of the Transistor which makes a larger electric current go through a different part of the Transistor, so technically a small electric current switches on a larger electric current.
How Are They Made?
A Transistor is made out of silicon. Silicon is commonly found in sand, and it’s a semiconductor, so it’s not conductive like a mineral such as copper, but it’s also not insulating like plastic. But if you do a process known as doping(a process when you treat silicon with impurities), then the silicon gains some “free” electrons. The impurities commonly used to dope silicon are, arsenic and phosphorus, but different minerals such as boron, gallium, and aluminum can be used.
Transistors are very important for almost all electronics, without them the speed and accuracy of our electronics today would be impossible.
A Cell is a very small and complex organism. There are an estimated, nearly forty trillion cells in the human body alone! But what is exactly a cell and what is its purpose in the human body?
A Cell like I said above is a small and complex organism, but there are more details to a Cell. A Cell is surrounded by a Plasma or Membrane, which covers the cell and separates it from the material outside the Cell. The center of a Cell is the Nucleus. The Nucleus determines how the Cell will function, inside the Nucleus it contains Chromosome, and inside the Chromosome is deoxyribonucleic, or DNA, and Ribonucleic acid, or RNA.
DNA is the molecule that contains all the information that is required to maintain and build a Cell. RNA is used to express the information that is stored in DNA. DNA and RNA are not responsible alone for the preservation and expression of the genetic material(s).
Proteins are the second type of intracellular molecule. Protein substances are created by chains of smaller molecules, called Amino Acids(Amino Acids serve a variety of purposes, including catalytic and structural).
The inside of a Cell is very busy and crowded. This is because a Cell contains many structures, liquid substances, and cytoplasm. A lot of action goes on in a Cell.
This is my report on the Human Cell.
