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.
The most obvious way to determine the evolutionary relationship of organisms (i.e. their phylogenetic tree) is compare morphological similarities For example: However, it is not easy to construct phylogenetic trees and there is often controversy among systematists (a phylogenetic tree is a hypothesis on how a group of organisms might be related). Some organisms that appeared closely related in some respects, may seem more distantly related in other respects.
