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 more closely the organisms are related, the more similar the homologous structures between organisms. Most examples of homologous structures revolve around the limbs of the species being compared. The bone structure within those limbs are similar between closely related species. Examples of Homologous Structures. Many mammals have similar limb structures. The flipper of a whale, the wing of a bat, and the leg of a cat are all very similar to the human arm.
