WebThe constant k is called the decay constant, which controls how quickly the total number of nuclei decreases. The value of the decay constant is specific to the type of decay … Decomposition is the process in which the organs and complex molecules of animal and human bodies break down into simple organic matter over time. In vertebrates, five stages of decomposition are typically recognized: fresh, bloat, active decay, advanced decay, and dry/skeletonized. Knowing the different stages of decomposition can help investigators in determining the Post Mortem Interval (PMI). The rate of decomposition of human remains can va…
