Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements

Showing Demography through Human Populations Both Pre- and Post-1950 OR I See Trends in Dead People I. Purpose: Is there a correlation between age of death before 1950 and after 1950 due to underlying factors? Between both sexes before and after 1950 from discriminating factors? What types of factors‚ and why? II. Hypotheses Within death rates and the factors that affect them‚ I hypothesize that death rates of both males and females will be higher in the younger populations before 1950
