The stabilizing process is one that results statistically in an over-represented norm. At the end of breeding season, the researchers sifted through their results and discovered that competition for resources was a bigger driver of natural selection than predation. Egyptian Vultures throw stones to crack open ostrich shells, while Song Thrushes batter snails against a stone "anvil" to break them apart. Stabilizing selection is the most common of those processes. Ecology considers the structure and function of the web of life at a hierarchy of levels: An individual organism is defined, in an evolutionary context, as a genetically unique entity. Safety engineers often calculate the danger threshold for the electric potential on a person by modeling the person as a spherical capacitor of radius R=1.8mR=1.8 \mathrm{~m}R=1.8m. What electric potential corresponds to the threshold value U1=150mJU_1=150 \mathrm{~mJ}U1=150mJ of stored energy at which a spark could ignite the dust and set off an explosion? Which of the following best represents the overall growth rate of a population?

When mature, all cells in a spine are dead, and even when the spine is still growing it has living cells only at its base. The explosion of technological advances in high-throughput sequencing (HTS) is starting to change this trend and holds great promise in applying non-biased approaches in the quest for de novo discovery of 'migratory' genes. However, this does not mean that all individuals are exactly the same.
