Photosynthesis is an amazing process that transpires inherently and is one that is required for all living organisms to sustain existence on this planet. The efficiency of this process has sparked inventions, such as the semiconductor-based solar cell, that would allow humans to produce energy in a way that is very similar to that of a plant’s photosynthetic process. In this paper, I will compare and contrast the photosynthetic process with that of semiconductor-based solar cells in their capacities to generate energy while also explaining the application of thermodynamics to each process. In order to discuss the photosynthesis and the semiconductor-based solar cell, it is crucial to understand what is involved in each process and how they could be different or the same. Photosynthesis is the process by which plants and some bacteria use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the fuel used by all living things. The solar cell connects solar energy to convert it into electricity, which is required by all humans. This process can be understood as solar electricity, which is created by using Photovoltaic technology, which is converting solar energy into solar electricity from sunlight. This system is providing sunlight to everyday use constituents such as computers, lighting and electrical equipment. The foremost contrast between photosynthesis and semiconductor-based solar cells is that they require solar energy, or sunlight, to commence the processes. In photosynthesis, plants use chlorophyll, often found in green leaves, to engross solar energy from the sun. Likewise, a semiconductor-based solar cell utilizes photovoltaic (PV) panels, very similar to plant leaves to absorb light. The manner in which light is converted in…...

...English Composition 15 Jan 2015 Introduction Se Habla Espanol is an essay written by Tanya Barrientos takes readers on her personal journey from childhood to adulthood as she begins to embrace her culture. She was born in Guatemala and came to the states at a very young age. Her story touches briefly on different periods of her life as she ages and details her state of mind as she originally did not identify herself as a Latina. Main Points Barrientos’ family moved to the United States when she was just three years old. The family settled in the state of Texas. At this time, the year being 1963 there was a common stigma against people who held on to their culture. To combat this stigma and ensure their children did not have a rough time they changed the way the communicate. Barrientos regularly recalls hearing her parents speak to each other in Spanish, but they would only talk to her and her sibling in English (Roen, Glau, & Maid, 2011, p. 59). Having the Spanish language effectively eliminated from her household at such a young age had a few adverse effects. Barrientos recalls having a sense of pride when being told that she did not seem Mexican by her friends. Between the ages of 7 and 16, her perception of speaking Spanish was a direct correlation between poverty. Her contention for the culture and wish to not be a part of the Latin label resulted in her saying to her father that she hated being called Mexican when she was 16. Her father sent her to Mexico......

English 115 Assignment 1

...Vontesch Barnes “On Becoming a Writer” Strayer University – English 115 Assignment 1 “On Becoming a Writer” Russell Baker “On Becoming a Writer” conveyed how he had a dream to become a writer. The main point that I took from this passage was that things happen unexpectantly. If you have a dream entertain it, because you never know where your pursuit will lead you. Russell looked at writing as something that was done by only the rich. He never imagined that becoming a writer could be a career that he could potentially get paid from. What I took from this was that he treated writing as a hobby or something liked he liked to do. Although writing was Russell’s dream, he still only thought of it as an Interest until he met Mr. Fleagle. It seemed that even though he had not been taught by Mr. Fleagle, he already had a preset judgement of how he was going to be. “He was said to be stuffy, dull, and hopelessly out of date. To me he looked to be sixty or seventy and prim to a fault”. One point I got from this was that the answers to life’s mysteries, even your dreams may come in a form you wouldn’t expect. Russell didn’t like English, the assignments or writing papers for the class in general. After some time in Mr. Fleagle’s class he was given an assignment called “What I did on My Summer Vacation”. This is the assignment that eventually lead him to discover his passion for writing. Instead he wrote a paper titled “The Art of Eating Spaghetti”. Russell pulled from a......

Sci 228 Ilab Week 1 Assignment

...iLab week 1 Essay SCI 228 Nutrition, Health, and Wellness iLab Week 1 Essay There are 14 parts of the digestive system. They include the salivary glands, tongue, pharynx, esophagus, stomach, liver, pancreas, gall bladder, small intestine, large intestine, appendix, rectum, and the anus. Food we eat first enters our mouth, which is where you find the tongue. We know it’s in there because it tastes the food we put in our mouth. You will find the salivary glands in 2 spots, under your tongue and behind your tongue. The best way to remember that it’s located there is to known that it releases saliva and there is always saliva on your tongue. Our pharynx is found in the back of the mouth. To remember it is located there I use the first half of the word which sounds like far, and then use that as a saying. The Pharynx is the start of a far travel. This is down the esophagus. The esophagus starts at the back of your mouth and runs down into your stomach. I remember it’s located there because I feel food go down my esophagus when I touch my neck. Our stomach is located underneath our heart. Most people love food. I use that to remember where our food goes after we swallow, under the heart into the stomach. The pancreas is located behind the stomach. It’s located behind the stomach because it needs to use the blood streams coming out of the heart to add enzymes it made. After the stomach, food will go into the small intestine. The best way to remember that the small intestine...

These reactions generate heat that, in turn, creates steam that runs the generators to produce electricity. Approximately 1/8th of the electricity produced in the world is derived from nuclear power. In this assignment, you will analyze the use of nuclear power as an energy resource. Respond to the following: •Discuss the scientific and technical concepts related to the use of nuclear power as an energy resource. Address the following in your response: oHow is energy released in a nuclear reaction? oHow are nuclear reactions controlled? oWhat elements are involved in nuclear power production? oWhat nuclear forces are involved? •Explain the advantages and disadvantages of nuclear energy, detailing issues related to production, delivery, cost, radiation, air quality, and waste. •Identify a country whose electricity production infrastructure relies heavily on nuclear power.

Many imaging techniques inject small amounts of radioactive material into the body, which are then tracked by a sensing device specific to the type of radiation emitted from that material. Radiation has also been used to destroy diseased tissue, typically beyond the reach of standard surgical techniques. Using the readings for this module, the Argosy University online library resources, and the Internet, write a paper on nuclear medicine. Address the following: • Explain the scientific and technical concepts related to nuclear medicine. Consider the following questions when you construct your response: o What type of radiation is typically exploited in most nuclear medicine procedures? o How are patients prepared for nuclear medicine procedures? o What are the advantages and limitations of nuclear medicine? o What ailments are typically diagnosed and treated via nuclear medicine procedures? • Evaluate a minimum of three applications of nuclear medicine relating to any of the following topics: o Positron Emission Tomography (PET) scans o Gallium scans o Indium white blood cell scans o Iobenguane scans (MIBG) o Octreotide scans o Hybrid scanning techniques employing X-ray......
