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.
Answer:
B
Explanation:
To begin with, it is clear that this cell has a cell wall (the rigid cubicle like structure around the cell). Only plants (that can carry out photosynthesis) have a cell wall. Secondly, one can view the chloroplasts in the cell (the organelles with green pigments inside). This is where photosynthesis takes place in the cell.

Answer:
level consumers in the food chain are carnivores (flesh-eating), insectivores (insect-eating), or omnivores (flesh-and plant-eating). A wetland example of a food chain: pickleweed, is eaten by salt marsh harvest mice, which are eaten by clapper rails, which are eaten by peregrine falcons.
