Chemistry of Living Things Essay

… Chemistry of Living Things

Basic chemistry dictates that matter refers to anything which occupies space and has mass. Elements are the smallest form of matter which cannot be broken down further to a simpler form. Examples are aluminum and iron. An atom is the smallest functional unit of matter that can take part in a chemical reaction and they are what make up elements. The atom has the particles that are positively charged known as protons, an equal number of neutral particles known as neutrons. Protons and neutrons are found in the nucleus. There are also the particles that are negatively charged called electrons that orbit around the nucleus. In most cases, the number of protons is equal to the number of electrons making the….

Chemistry and Photosynthesis Chemically Speaking Term Paper

… chemistry and PHOTOSYNTHESIS

Chemically speaking, photosynthesis is the utilization of sunlight by plants for the conversion of carbon dioxide into organic matter. In green plants like trees, shrubs, flowers and conifers, the overall chemical reaction may be represented by the balanced equation CO2 +H2O{CH2O}+O2 in which the newly-formed organic matter is represented by CH2O, a generalized formula for a carbohydrate. The overall process by which green plants convert sunlight to food can be expressed with the equation 6H2O+6CO2C6H12O6+6O2 which translates to "six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen" (Farabee, Internet).

The importance of this rather simple process lies in its conversion of energy from radiant (i.e., sunlight) into chemical form (i.e., sugar).…. [read more]

It's also vital to bear in mind that Priestly was a pneumatic chemist; there were many pneumatic chemists during this period as the result of the work of Stephen Hales, the man who had created the pneumatic trough around 500 years earlier (Ihde, 1990). This trough made it possible to isolate airs via decomposition of chemical matter and to gather the air free of contaminants. "Hales developed the apparatus because he was curious to learn how much air was trapped in various solids in non-aerial form. He measured the volume of air which could be driven out of various chemicals,…. [read more]

Reduction Oxidation Redox Signaling in Wound Healing Research Paper

… Redox

Reduction-Oxidation (Redox) Reactions and Signaling at Wound Sites: Implications for Healing

Wounds are a natural if not especially pleasant feature of life. All living organisms will experience some sort of unwanted damage to their outer layers potentially due to no more than some wind blown debris, or to their inner workings through the inhalation or uptake of some microscopic infectious agent. In order to combat such instances, all organisms have developed certain methods for reacting to wounds and infections that include the development of special cells whose sole purpose is the destruction of foreign cells, and others that are meant to promote healing and to reinforce protection by providing necessary chemical enhancements. Though the mechanisms by which these processes are carried out are still…. [read more]


Science What Are the Steps Book Review

… What is the structure of an atom? What particles are in the nucleus? What is their charge and mass? What particles are outside the nucleus? What's their charge and mass?

An atom is comprised of electrons, protons, and neutrons. Inside the nucleus are protons and neutrons. Protons have positive charges and neutrons are neutral. The atomic mass will equal the number of protons plus the number of neutrons in an atom. Outside the nucleus are the electrons, which have negative charges.

Modern Miniaturization

Contrary to the contemporary trend to supersize fast food portions, which Jennifer O. Fisher and Tanja V.E. Kral (2007) note in the article, "Super-size me...," manufacturers routinely reduce the size of electronic components. As this practice of downsizing electronic components contributed to improvements in integrated circuit technology and fabrication processes, it simultaneously led to electronic devices and related peripherals becoming miniaturized.

Origin of Life Essay

… ¶ … Origin of Life

There are currently many different competing theories on how life originated on this planet. One of these theories involves the early state of the atmosphere. According to this theory, the first step in the origins of life was the spontaneous formation of carbon compounds in Earth's then carbon-rich atmosphere. There is substantial evidence that these compounds could have formed -- they are a common occurrence throughout space, and experiments have shown that even amino acids, the building blocks of proteins, can be formed under conditions similar to those that existed at a certain point in the Earth's past. The theory goes that after these amino acids and other organic compounds formed, they eventually came together to form more complex systems,…. [read more]


Biology Living and Non-Living Things Essay

… Biology

Living and Non-Living Things. Biology is the study of living things. Biologists are scientists who specialize in the study. They discovered more than a million life forms on earth, some of them living and some are not (Buckley 2003). They distinguish living things from non-living according to certain characteristics. These are nutrition, respiration, excretion, reproduction, growth, sensation, movement, transport, secretion, metabolism and regulation (Buckley). Other scientists recognize a living thing when it is composed of cells, requires energy to function and survive, display a hereditary pattern, responds to the environment, maintains homeostasis, and evolves and adapts (ThinkQuest Team 2000).

Nutrition means that living things eat to stay alive (Buckley 2003). Plants use energy from light to produce their food, while animals feed on plants…. [read more]


Properties of a Carbon Atom Term Paper

… -Describe the basic characteristics of cancer cells?

Cancer cells can be deadly and harmful to all the living things they come into contact with. Cancer cells lose the ability to communicate with other cells through chemical signals. They also lose sensitivity to anti-growth signals from surrounding cells. These signals normally restrict cellular growth. Cancer cells do not have a fixed lifespan. As long as they are able get the nutrients needed to survive, cancer cells are essentially immortal. They will continue to live and divide at an uncontrolled pace unless something happens to stop them. Malignant cells that cause cancer all have the ability to evade the body's cancer surveillance system as well.

Black Dog of Fate by Peter Balakian Term Paper

… Black Dog

Creating a World View from the Black Dog of Fate by Peter Balakian (1998)

Freedom is not simply about doing whatever one chooses. It is about taking responsibility for learning about the condition of the world and what happened to one's ancestors. It is also about using one's freedom and prosperity to help other people during their time of need, even if they live far away, in respect for what one's ancestors have suffered.

In 1915, even before the Nazi-perpetrated Holocaust, the Turkish government slaughtered more than a million Armenians. Every time when such an atrocity has become worldwide knowledge, the powers that be shake their heads and say never again. However, much like Peter Balakian, before reading The Black Dog of Fate,….

Demand for Suvs, Hybrids Research Paper

… For drivers who need large utility vehicles like trucks for works, hybrid technology has proved to be disappointing. Overall, the "the hybrid has a greatly-reduced towing capacity and payload, which is most likely due to the addition of the electric motor and batteries" ("Advantages and disadvantages of hybrid trucks," Cars Direct, 2009). Given the higher initial purchase cost with reduced power, this has caused many to go with the non-hybrid option if they use their vehicles commercially and must rely on the vehicle in all weathers to do heavy-duty activities.

In terms of overall customer satisfaction, statistics indicate that it is relatively low for hybrids. "Only 35% of hybrid car owners bought a hybrid again when they purchased a new vehicle in 2011" (Kim 2012).…. [read more]

You must be able to search through the debris for burn patterns and incendiary sources while taking pains to preserve evidence.

People also do not realize how a…. [read more]


Psychoanalytically Interpreting Rapunzel Essay

… Rapunzel

The Grimm brothers' fairy tale "Rapunzel" is ripe for psychoanalytic interpretation because it includes a number of peculiar textual details requiring analysis. In particular, the way the story is broken up into three distinct parts and the relation these divisions have to the characters (especially the prince and the enchantress) demonstrate how the story formulates the journey from child to adult as one of a conflict and eventual reconciliation between the notions of eros and thanatos. Examining the function of the prince and the enchantress in relation to Rapunzel reveals that they serve as representations of eros and thanatos, respectively, ultimately explaining some of the more mysterious details of the text. The story is making a claim regarding the importance of reconciling death with…. [read more]
