Answer:
metal
Explanation:
Metals have unique characteristics that differ from other substances: they are solid, do not let light (they are opaque) and conduct electricity and heat well, having a special shine called metallic. When heated they are malleable and can be molded into various shapes, from wires to plates and bars. For these reasons, we can say that a malleable and ductile material - or capable of being hammered into different shapes without breaking and being pulled by a wire - is probably a metal.
Pollutants can change the chemical composition of an ecosystem; in turn the organisms have to adapt to the changes or move out.
Answer;
-A high degree of unsaturated bonds
In general, the lipids that we refer to as oils at room temperature have a high degree of unsaturated bonds.
Explanation;
-Lipids are fatty, waxlike biomolecules found in the human body and other organisms. They serve several different roles in the body, including fueling it, storing energy for the future, sending signals through the body and being a constituent of cell membranes, which hold cells together.
-Fats and oils belong to a subgroup of lipids, called glycerides, that consist of three fatty acids and a glycerol backbone. Oils are composed of triglycerides, predominantly unsaturated fatty acids. They are liquid at room temperature, even if the fatty acid chains are long.
Mutations allow organisms to expand their capabilities and abilities to use the resources in the environment. If mutation happens, new species could be discovered and this would increase biodiversity in the ecosystem. Hope this answers the question.
