Is ductility considered as a physical property or a chemical property
Elena L [17]

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.

Ainat [17]
The answer is C.)sending them on the shuttle to be suspended in space. This is the answer because  after  the nuclear fuel rods come out of the reactor, they go into a deep pool to cool off. Then they are then stored in concrete and lead-lined casks for dry storage, until, ultimately, the US government builds a deep underground storage facility to house them permanently. They are never sent on the shuttle to be suspended in space<span>. It would be too costly and too dangerous.</span>

You see an entire pond, with the same plant across most of it. The plant seems to be surviving very well. Which adaptation does
faust18 [17]

Answer: One advantage is, well, the water. There’s plenty of it and it’s all around. Therefore, most aquatic plants do not need adaptations for absorbing, transporting, and conserving water. They can save energy and matter by not growing extensive root systems, vascular tissues, or thick cuticles on leaves. Support is also less of a problem because of the buoyancy of water. As a result, adaptations such as strong woody stems and deep anchoring roots are not necessary for most aquatic plants.
