Matter(物质)is always changing, either physically or chemically. If a material goes through a physical change, it is still the same material. During a chemical change, one kind of matter changes into another completely different kind of matter. For example, when we burn wood or cook fish, ...
Physical & Chemical Change:There are two kinds of changes possible during a process: chemical and physical changes. A chemical change brings a change in the chemical composition of a compound. However, a physical change keeps the chemical composition intact but varies the p...

12C-DNA were in 1.695–1.699 and 1.687–1.695 g mL−1, respectively (Supplementary Fig.11). This minimal change (0.008–0.012 g mL−1) of buoyant density suggested a poor fractionation of AOA, in comparison to AOB, across both plastisphere and seawater. Sequencing of ...
