Ductility is a physical property.
A physical property of a material is a property that can be measured or observed without changing the composition of the material.
In this case ductility is a physical property. It is defined as the property of a material associated with the ability to be drawn or stretched into a wire without breaking. The chemical identity of the material is not affected, that is it does not change.
Example of ductile materials include gold, silver, copper, erbium, terbium and samarium.
Other examples of physical properties are:
1. Solubility
2. Melting point.
3. Boiling point.
4. Color
5. Density.
The piano could only be played with 12 fingers, which is rare because humans normally have ten fingers.
Well, the domain humans belong to (when I did a little research) is that they are actually a Eukaryote. Therefore, I'd say C, Eukarya. I hope this helps! ~Mia
