Multiply the percentage of time in each phase by the total time of the cell cycle (720 minutes) and this gives you an estimate of the time spent in each phase
they share 50% of their genetic information with each other.
Scientists use several methods to determine the proximity between species. Two of those methods may be an anatomical comparison, by examining the skeleton structure of two species, and DNA composition comparison, by comparison of genes, or specific parts of the DNA, that allow establishing the relative distance between species.
