Overall, life expectancy fell by one-tenth of a year, from 78.9 in 2014 to 78.8 in 2015, according to the latest data. The last time U.S. life expectancy at birth declined was in 1993, when it dropped from 75.6 to 75.4, according to World Bank data. The overall death rate rose 1.2 percent in 2015, its first uptick since 1999. More than 2.7 million people died, about 45 percent of them from heart disease or cancer.
interphase is the phase that takes up most of the cells life. In interphase their are three parts: G1, S, G2. Interphase is basically preparing cell for cell division. After iâ¦nterphase takes place, then the cell division takes place with Prophase, metaphase, anaphase, and telephase.
The eukaryotic cell cycle is divided into two major phases: interphase and cell division. A. Interphase. Ninety percent or more of the cell cycle is spent in interphase. During interphase, cellular organelles double in number, the DNA replicates, and protein synthesis occurs. The chromosomes are not visible and the DNA appears as uncoiled chromatin. Interphase is divided into the following stages: G1, S, and G2. During G1 phase, the period that immediately follows cell division, the cell grows and differentiates. New organelles are made but the chromosomes have not yet replicated in preparation for cell division.
