Specify volume and select unit of volume measurement. Then, select material for which to perform the calculation, and press Calculate button. The weight of the selected material is calculated based on the material density and its given volume.The number enclosed in square brackets is the item's density in kilogram per cubic meter. The calculator converts the weight, volume and density into many units of measurement.he weight of the selected material is calculated based on the material density and its given volume.

Scientists can tell whether organisms are closely related by  comparing their DNA. This will allow then to look at various traits  and features so as to compare the relationâ¦ship between organisms.
Molecular Phylogeny. Phylogenetics is the science of estimating and analyzing evolutionary relationships. Phylogenetic relationships among micro-organisms are especially difficult to discern. Molecular biology often helps in determining genetic relationships between different organisms.ne advantage of the molecular approach in determining phylogenetic relationships over the more classical approaches, such as those based on morphology or life cycle traits, is that the differences are readily quantifiable.
