3. Who Can I Pay To Write My Essay - " HelpWriting.Net ". Biology Major Essay My listed major at George Mason University is Government and International Relations. Prior to being an humanities major, I was a biology major. After switching over to my current major, I continued taking courses in the natural sciences, courses specifically fulfilling the prerequisite courses for admission into Dental School. I do truly enjoy my current major, but I believe it would be more fitting for this paper to be written from a biology standpoint. This excerpt will touch on the study of biology, and science subfields and their use in career paths such as Dentistry. In accordance with Oxfords English Dictionary definition, biology is defined as "The study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behavior, origin, and distribution."

Most of the time they were based on what I saw other people, who I looked up to doing. My cousin Courtney was a lifeguard, so I wanted to be a lifeguard, my mom was a nurse, so I wanted to work in the medical field. Then I would be watching sporting events with my dad, and I wanted to be a sports journalist/reporter. It wasn't until high school that I really started to look at what I liked to do and what I was good at. During high school, we were forced to look at different careers and fields of study weekly. I had known that the STEM field was most appropriate for me. I was all in on being an engineer of some sort, but after taking an engineering class, I quickly changed my mind. Then I thought about math and physics. I did very well in math and physics just applied those skills. However, I found them to be quite boring after a while. So, within the last year, I have been looking more seriously into chemistry of biology. Chemistry was my favorite high school... Show more content on Helpwriting.net...

7. Can I Pay Someone To Write My Essay - " HelpWriting.Net ". Biology And Life : A Study Of Life College is a time of finding out who you really are, what you like, what you hate, and what you want to do for the rest of your life. In High School, you did not have to know what you wanted to do, and if you did, then kudos to you. Most college students do not know what they want to major in and that's okay. It means that you're waiting for something to "click" with you. I understand completely, I spent a while myself not knowing what I wanted to major in until one day I realized how beautiful life is. That's when it clicked for me to major in biology. Biology is derived from the two Greek words, "bio" which means life, and "logos," which means the study of. Biology is the study of life and living organisms. When someone mentions biology, what comes to mind? Do memories of learning about how Monarch Butterflies migrate to Mexico to hibernate come to mind? That's a miracle of nature. The actual definition of biology as transcribed from the Merriam–Webster Dictionary says, "A branch of knowledge that deals with living organisms and vital processes. Which also includes the plant and animal life of a region or environment and the life processes especially of an organism or group" (Merriam– Webster).

Tasks such as walking, breathing, and digesting what has been eaten are sometimes considered mundane, even taken for granted. One such process that is necessary to maintain life is diffusion. Diffusion is a key factor in moving ions, fuels, and other molecules into and out of the blood. It is one of the most important components in supplying oxygen to the alveoli and removing carbon dioxide. Without diffusion, substances would find it very difficult to pass through membranes and could cause detrimental effects to the human body. The paradox scientists have drawn is...

Materials/Methods: In order to properly experience each of the simulations it is necessary to have access to Microsoft Excel and MatLab, a program designed allowing scientists to view data in a visual format. The first simulation, as mentioned, dealt with a single molecule randomly moving in an open area. It is assumed that the molecule will move from a higher concentration to a lower concentration based on the laws of diffusion and that the molecule will move a set distance in one step before heading randomly into its next direction. The molecule will proceed randomly through several hundred steps and countless collisions with a fixed free path length, or the average distance between each collision. The second simulation demonstrates several molecules randomly moving in a designated area. This simulation is similar to the first in that it is also a random walk with a fixed free path length and random direction after each collision. Ten thousand molecules start at the origin to show this relationship because we are assuming that the molecules have no size, however this would not be physically possible outside of the simulation. Again the assumption is made that the molecules will move from a higher concentration (near the origin) to a lower concentration (away from the origin.)

Climate change is altering the pattern of life on the planet, causing widespread species extinction, migration and behavior changes (Suzuki, n.d.). For example, female caribou migrate in the spring to small pockets of vegetation where they feed and raise there calves, but for the last decade spring has come so early that by the time the caribou reach the coastal plan, their principle of food plant has already gone to seed (Suzuki, n.d.). This proves that the female caribou are going to have to change breeding time frames, as well as migration, which will have an overall affect on the ecosystem. This also means that animals and plants will have to permanently migrate to find suitable habitats but some will not be able to move fast enough to keep up with the pace of climate change (Suzuki, n.d.). In fact, by saying that it means that some species will have to move 10 times faster than they did during the last ice age just to survive. Over 30% of land surfaces in Canada will require unrealistically high migration rates to keep up with projected climate change (Suzuki, n.d.). Another example of this issue is with Collared Lemmings. They are an important prey for snowy owls, which may lose as much as 60% of their habitat. Loss of tundra habitat could radically reduce the availability of vital breeding habitat for millions of geese and shore birds (Suzuki, n.d.).

One of our assignments this semester was an outside of the classroom volunteer project. For this project I was selected to participate in the Tri– Beta Breast Cancer Walk. As participants, we had to do several things to prepare for the volunteer event including a learning session. During this session, we learned exactly what breast cancer is, the different types, and the main causes. I further learned about breast cancer through a scientific aspect in my biology class. We learned that cancer is when cells are over actively reproduced, which is caused by a mutation in the cell cycle and suppresses our bodies ability to function normally to stop this. Also, we learned about some of the different subtypes of breast cancer like, HER2+ (ER–), Basal– Like (Triple Negative Breast Cancer), Normal–Like, Luminal A, and Luminal B. HER2+ (ER– ) breast cancer is less common, but it is very aggressive. HER2 is a gene in our bodies that produces receptor proteins, which are responsible for regulating the growth and repair of breast cells. When these HER2 receptor proteins are expressed too much, it causes excessive reproduction of breast cells. It is thought that African Americans have a higher risk for this type. Basal –Like, or more commonly called, Triple Negative Breast Cancer is very aggressive, usually the most aggressive.
