Decomposition

“Memento mori” is a Latin expression that roughly translates to “remember that you are mortal,” or “remember that you will die.” We all strive to live our lives as best as we can, but never forget that we are mortal and at some point everything will come to an end for oneself. Everybody has undoubtedly pondered at some point about what lies beyond death. While most people focus on where their soul and consciousness will go beyond the grave, Mary Roach’s “Stiff: The Curious Lives of Human…

By: Jettica Williams BIOL 1107 Lab October 10, 2016 Prepared for Mrs. Whitney Lab Course Introduction: During this experiment, we investigated the alcoholic fermentation in a single- celled fungus, which is yeast. Fermentation is activity of decomposition carbohydrates whereas deterioration incurring foods have protein. During the fermentation process usually do not generate reek and usually produced carbon dioxide gas, but marked by hydrogen sulfide gas (Desrosier, 1998) Alcoholic…

There are so many misconceptions arise when you talk about a person having an autopsy. First of all people think that everyone has an autopsy upon the calling of death. Second people think that person is automatic identified and what happens to their personal effects care for? Next, people think that the organs are kept and donated to other individuals. Another question I get all the time is that is there time where the body will sit up on its own after death. Finally is that what happens to…

gets to the hard surface first, the zebra muscles will lay on top of the natives and kill them. The most common invasive plant species is the purple loosestrife; “the invasion of purple loosestrife into North American freshwater wetlands alters decomposition rates and nutrient cycling, leads to reductions in wetland plant diversity, reduces pollination and seed output of the native Lithium alatum, and reduces habitat suitability for specialized wetland bird species…” (Blossey, Skinner, & Taylor,…

A problem that is affecting humanity every day, and it is gradually intervening in our lives is global warming. This is a phenomenon that shows an increase of the temperature in the atmosphere and oceans. Gases and substances produced by humans are changing the planet and causing severe effects in the stability and development of different forms of life. The changes in climate and weather that are currently known are causing environmental disasters that attack directly our lives and living…

polycondensation has 3 main steps: 1. Removal of water. 2. Polycondensation of oligomer. 3. Melt condensation that makes PLA with high molecular weight. Direct polycondensation of lactic acid is the modest reaction that forms lactide simultaneously by the decomposition processes and it is not used for the large production of PLA [19-22]. Back in the days, the direct polycondensation was assumed as the reaction that produces inadequate polymers with low molecular weight. But with the…

animal pests, pathogens, diseases, and predators. One catastrophic biotic factor are soil organisms. These include bacteria, fungi, earthworm, rodent, termite, etc. In terms of beneficial effects, these organisms can supply nutrients or help in the decomposition of plant materials. On the disadvantageous side, soil organisms can cause diseases, reduce quality of crops, or open up wounds on plants for other pathogens to enter (passnownow.com). Another deadly biotic factor is the multitude of…

The novel Night is Elie Wiesel’s memoir that shows his traumatic experiences during the Holocaust and how the Holocaust changes him from a spiritual, sensitive young boy to a unspiritual, internally dead man. The changes that take place in Elie’s life are very evident as you read his memoir. The Holocaust began January, 30th 1933 and ended May, 8th 1945. These 13 long years were a life time for many jews, in this period of time they not only lost many family members and close friends, but many…

I will discuss and compare three authors’ theories of substance, Descartes, Anne Viscountess Conway, and G.W. Leibniz. I will briefly summarize Descartes’ theory of substance. I will outline the two additional theories of substance by Conway and Leibniz. I will discuss how they relate to Descartes theory. I will discuss the interesting difference in the role God plays in the two latter theories as contrasted with Descartes’ theory. I will examine striking similarities and also the differences…

Precipitation reaction, or otherwise known as double-replacement reaction, is one of the three common types of chemical reactions along with decomposition and combustion. A simple definition for the precipitation reaction would be “atoms from two different compounds switch places” (Lew 40). This means that one of the reactant’s molecule “trades” places with another from another compound to form products, like a precipitate, hence the term double-replacement. A precipitate is usually a solid…
