The carbon cycle deals with the interaction of carbon between living organisms and the nonliving environment. This cycle is a process through which all carbon rotates. The main result of the carbon cycle is to serve as a great natural "recycler" of carbon atoms.
Phosphorus is one of the major minerals required by chicks. The cost of inorganic phosphorus supplementation is the third most expensive cost in feed. Optimizing phosphorus utilization might reduce feed cost in addition to reducing phosphorus excretion into the environment. Phosphorus is a very important mineral in animal nutrition especially for fast growing animals. Phosphorus is the second most abundant mineral in the animal body, approximately 80% of which founded in the bones and teeth. As with calcium, the formation and maintenance of bone are quantitatively the most important functions. About 20% of phosphorus not present in the skeletal tissues is widely distributed in the fluids and soft tissues of the body, where it serves a range
In the movie, Whale Rider, there are great examples of Joseph Campbell’s article, Four Functions of Myth, which are: mystical myth, cosmological myth, social myth, and psychological myth. In the film, Whale Rider, Pai discovers her sense of self as she reinvents the Maori tribe’s creation myth to save the dying culture.
9. Chemists meet the demands of energy by finding ways to conserve, produce and store energy.
The Phosphorus cycle is a type of chemical element made up of all compounds forms. One of the compound forms is phosphate ion, the chemical structure for this is (PO42) this can be found in water, soil and sediments.
Currently, because our chemical teacher just had her baby and is on maternity leave, we have a problem that we are going to take AP chemistry but we do not have chemistry lesson now. Some students say that we can study by ourselves for this special time. However, it is refuted by saying that if we have some problems, we do not have someone to ask. An alternative approach is to invite a temporary teacher. However, it is not easy to find a teacher in such a short time. From my personal perspective, it is feasible to study by ourselves temporarily and ask the questions when our chemical teacher come
The 13th element, Phosphorus, was first discovered in 1669 by a German alchemist by the name of Hennig Brand and since then we have to come to find out that the element has had a larger effect on different aspects of our lives. Though Phosphorus was a great discovery for the scientific fields it also came with a dark side that was taken advantage of in the 1800s. Phosphorus. Also in the 1800s, phosphorus grabbed hold of the industrial scene which in turn changed the way people work and how they were treated. Currently, we are dealing with a problem called “nutrient pollution” which is an excess of phosphorus in the air.
After taking AP Chemistry, I knew that I wanted to study chemistry in college. I also have been a very inquisitive person my whole life, wondering why things are and how things worked. My inquisitive nature and love of chemistry is why chemical engineering appeals to me. I am drawn to Biomedical engineering due to its application of both chemistry and biology to solve medical problems. Doing a complete 360, I am interested in art history, because not only do I find art fascinating, but I also find it mesmerizing how artists visually represent and were inspired by the world around them.
In the beginning of my junior year, I had signed up for one of the most intimidating classes in my high school, AP chemistry. While I took chemistry honors, I heard rumors about the AP course and seen homework packets that overwhelmed me to the point of removing the class from next year’s schedule. However, out of impulsiveness, I decided it was time for a challenge and put the course back on my schedule. When I received my summer assignment for the course, I felt confused and regretful about the decision I had made. My commitment to not fail the class the first week back from break forced me to focus on the time-consuming homework. From my struggle, I managed to finish the packet on time. The school year began, and one of the first lessons
I’ve always heard that some trials are caused because of our own actions, I discovered this firsthand when I enrolled in AP Chemistry. I'd never taken Chemistry before, but after talking with the teacher we concluded that I would do fine in AP as long as I was willing to work hard. Chemistry didn’t come easy for me. I felt like things weren’t clicking as quickly as I wanted. When I read from the book I had a difficult time understanding what I was reading. So I started sacrificing my hour lunch to get help from my teacher. Nearly every day I ate lunch while getting help on chemistry homework. At home I spent most of my time doing the same homework. I'd do the problems I knew how to do, then the next day I came to class and lunch prepared with
In recent years, the oil and natural gas industry has continued to expand to populated areas, thus growing a concern for nearby communities regarding volatile organic compounds (VOCs) air toxics and human exposure.1 Current screening methods to determine exposure of toxic VOCs such as the family of Benzene, Toluene, Ethylene and Xylene (BTEX) requires a traditional gas chromatograph (GC), which requires high energy use and its bulky size is not ideal for long-term field deployment and real-time measurements. Sensor technology advancements have enabled the use of low-cost devices to measure VOCs, but require additional techniques for chemical speciation for BTEX identification (i.e.
The subject of Chemistry is one that deals heavily with a comprehension of the natural world and the individual details that make up an entire system. I was introduced to this course my sophomore year as I took on Honors Chemistry. As a student who grasps material best with hands on projects, this class fueled my excitement to be able to understand a complex subject using planned out lab procedures. From titrations to calculating the amount of copper in a solution, Chemistry gave me an opportunity to bring my own speculations into a class rather than being told directly what is occurring in a scientific process. The fascination of this class is what directed me to take AP Chemistry my senior year of high school. Even with the difficulty of
Starting in high school, I realized I was hearing conflicting perspectives from teachers and family. Some people claimed I was “gifted” that is; knowledgeable and creative, but I worked hard at tasks others seemed to find simple such memorizing, staying focused, and keeping organized. At first, I justified my lack of focus and incentive claiming the transition from middle school to high school had begun to affect me. The years past and my problem lingered, yet I sustained my belief that I had a problem until my grade point average reached my record lowest.
