...Just a few months ago, I was arguing with my mother about how chemistry is pretty much everywhere and no one seems to appreciate it. People do not get curious about how we are always using chemistry. It is like if people give for granted that things are the way they are because it is just the way it is. I have listened to the same phrase over and over again every time that I take a chemistry class, “why should we even have to take chemistry? It is not like I am using it every day!” The truth is chemistry is everywhere. Chemistry is even in the smallest and insignificant things like the glow sticks. How they work? What makes them glow? How is chemistry present in them? Glow sticks have plenty of uses. They are used for camping, diving, as a decoration, or just for fun. The only thing that needs to be done in order to make them glow is bend them. But there is something more deeply than just bending the glow stick. These glow sticks involve chemical reactions. The reaction of these chemicals causes a constant release of energy. Atoms in the materials are stimulated, causing electrons to get a higher energy level and then return to their normal levels. When they do this, they release energy as light. This process is better known as chemiluminesence (Harris, 2015). Moreover, light emitting...

...“Chemistry is a science that deals with the composition, structure, and properties of substances and with the transformations that they undergo” (Merriam-Webster. 2011). Thus saying, Chemistry is a major influence on our lives on a daily basis. You find it by the air that you breathe in, the food that you eat, and every object that you can see or touch is a fundamental of Chemistry. Throughout this paper, I will describe why chemistry is important, what is beneficial, and what I found interesting. In order for me to purse my degree in Chemical Engineering, it was a must for me to take Chemistry 1411. First, it was a pre-requisite for the following Chemistry classes for me to take. Second, the basis of this class is a fundamental pertaining to my degree because they have to apply the principles of chemistry to design and operation of immense chemical manufacturing process. I chose this major because my grandfather inspired me from such a young age to be in this field. I can remember him doing all kinds of experiments in his office trying to test and discover things that really drew my interest to this major. My grandfather demonstrated the benefits of Chemistry and showed me how it is ever present in our every day life. He also taught me that Chemistry is always changing in our world around us and I want to be apart of this changing process and help the world benefit from Chemistry. I hope to see myself in a couple years being highly successful and enjoying working for a refinery...

...Biology and chemistry are complimentary to each other; one cannot be studied in its entirety without the firm understanding of the other. Interactions between chemicals are what make up biological life, which makes up organisms. Organisms are living structures made up of cells that consist of animals, plants, and bacteria. They are biologically engineered yet composed of a multitude of chemical reactions. By examining organisms, their premise of living is based off of their ability to create energy. Chemistry is vital to the understanding of biology as seen with the chemical interactions that make up thermodynamics. Thermodynamics pertains to the change in energy and heat that occurs in all of matter. It is divided into categories of isolated...

...Personal Statement The enthusiasm I have for the sciences- especially chemistry, encouraged me to think about my future career and how a chemistry-related degree could be a possibility for me. My true passion lies in helping others in a safe and effective way through the use of innovative pharmaceutical medicines. I have become inspired by a personal ambition of becoming a Pharmacist as I aspire to improve people's daily lives. Ever since learning the fundamentals of chemistry, I knew this was the pathway I would follow. Chemistry at A-level has developed my understanding of the atomic structure, bonding and chemical mechanisms which I believe are elementary to studying Pharmacy. Its ensuing impulsion has also catalysed my grasping the biochemistry of biological molecules, such as enzymes in Biology. I have immensely enjoyed learning about the function of antibiotics in inhibiting the growth of bacteria, although bacterial resistance is still proving to be a huge problem for treating such infections. Laboratory experiments in both courses have greatly enhanced my practical and analytical skills. Equally, Physics and its application have improved my logical thinking, problem solving and data analysis skills. During the holidays, I spent a week shadowing a Pharmacist and dealing with different prescriptions, including giving advice to the patients and staff management, a challenging and intriguing experience which showed me how immensely cumbersome the Pharmacist's job...

The Oxidative Damage Theory and Free Radical Theory are two important theories that theorize why organisms age. Researchers have done experiments that discovered chemicals that speed up or slow down aging. A. Introduction 1. Topic sentence: Has anyone ever wondered why we age? Is it because of religious reasons, or are we genetically engineered to do so, or does the everyday changing world affect how we age. 2. The definition of aging and what humans characterize aging by. 3. How the chemistry of the human body leads to the biological changes which causes humans to age. B.

...and then explain how they work with physicians. What limitations do these professionals have versus a physician? Why do you think some physicians might oppose using these professionals to provide care? Do you think these professionals play a critical role in healthcare? Why or why not? I am going to talk about an OD Doctor of Optometry. The reason I am going to talk about this profession is because what would happen if we lost one of our senses like Vision. I know that that is one of the senses that I would hate to lose. I don’t mind losing my smell or taste or even touch. When should I decide that I want to go to Optometry School? Honestly I would get a head start when you are beginning your freshman year of college. There are 21 schools of Optometry in the United States including Puerto Rico. So you should have an idea on what school you would want to attend. Most doctors would say that they have a list of 3 or 4 schools that they would attend. They would contact the schools and see what is required for undergrad work. So I decided to check out NECO (New England College of Optometry) I chose NECO because it is one of the top schools in the country and it is based out of Boston too. Applicants to the Doctor of Optometry program need to demonstrate at least three years of undergraduate preparation. Within this period of study the student must have credits for the following specific course work: (NECO 2015) Biology with Lab 2 Semesters Chemistry with Lab 2 Semesters Physics...

...Phenylalanine is a critical and required amino acid for the normal biological productions of proteins. The body requires a certain amount of phenylalanine because it does not produce it naturally. The human body obtains Phenylalanine thru proper diet. Thru the biological process of protein formation the body converts phenylalanine into tyrosine, which is essential to form required chemicals and proteins that the body needs to functions normally. Deficiency of phenylalanine causes numerous healthy problems such as altered state of mind, lack of energy, memory issues, confusion, and decreased alertness. High blood levels of phenylalanine can also be bad. High levels of phenylalanine can lower intelligence, causes anxiety and depression, and the inability to focus or pay attention. This is why phenylalanine is such an important molecule. Too much of it can cause problems and a deficiency also causes health problems, therefore it is important to be educated about it. The IUPAC name for phenylalanine is (2S)-2-Amino-3-Phenylpropanoic Acid. There are also common names of phenyalanine, L-Phenyalanine and D-Phenylalanine. Phenylalanine is a nonpolar hydrophobic molecule, which is why it is buried inside proteins. Phenylalanine is an aromatic compound with a melting point of 283 degrees Celsius. It has a solubility of 26.9 grams per mole. The structural formula can be seen on the cover page and it’s molecular formula is C9H11NO2. Phenylalanine is found in protein. It is...

... 1,243 words A Veterinarian is a hard working individual who works hard to get and keep this respected job. Veterinarian Medicine originated back in 2,500 B.C, and it is still a job today. Of course it is much more advanced and now it takes a lot more work to have the title of Veterinarian. A veterinarian’s education is very important if they want to get into college and a job after school. The type of college the student goes to is very important too. It can affect where their job is or how much money they make. A veterinarian’s job is a good one and anyone with a passion for animals should try it including me. The education of a veterinarian is very important. In college and in high school education is important. In high school to get into a good college with veterinarian programs the student must take many courses. They include biology, chemistry, physics, calculus, trigonometry, statistics, environmental/earth science, English, computer science, history, and languages. The student must not only take these classes, but the student must get above a 3.0 GPA average to even think about getting into a veterinary college. Once the student gets into a college you must take many courses to get a job after words. In the first year the student must take English, zoology, and general chemistry. In the second year the student must take organic chemistry, general physics, and calculus. In the third year the student must take biochemistry and microbiology...

...Chemistry “Chemical Reaction and the PH Scale” Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. As you might imagine, it's useful to be able to measure the acidity of solutions. Scientists have come up with the pH scale for determining the concentration of acid in a solution so we can distinguish between solutions with varying acidity. A Chemical reaction is the outcome of two or more elements together results in the formation of a chemical bond between atoms and compound. Chemicals react together due to participating atoms. The reason why atoms react with each other is to reach a state in which their valence shell is filled. Reactions occur at different speeds, they have different rates of reaction. There are some things that must be considered in a chemical reaction. There are a few things that decide the course and speed of the reaction. One thing about chemical reaction is that, there is now known that there are three types of chemical reactions. They are classified into three types: exoergic (exothermic), endoergic (endothermic), and aergic (athermic). In these cases, energy is supplied, but the different types of reactions initiate the energy differently. First of all, Exoergic, or exothermic, reactions release energy during the reaction. ...

...them into groups, if only for the sake of convenience. The earliest attempt to divide elements into gases, metals, non-metals, and earths was made by Antoine Lavoisier. For many years after his organization attempt, scientists all over the world began to learn about elements and how certain ones were similar to others. They used this information to make their own version of how they should be grouped together. It was eventually recognized that there should be a universal table for grouping elements together. As stated earlier Dmitri Mendeleev is considering the father of the periodic table of elements. Although he did develop what is essentially the foundation of the table we use today, it was actually Glenn Seaborg who finished his work and made the table that everyone uses today. Seaborg and his colleagues discovered the final elements on the table and...
