1.   How did the planets pick up the necessary angular momentum, and why do the planets have different chemical compositions?

2.   Not all magmas have the same composition, and magmas with different compositions melt at different temperatures.

3.   Now, leaving aside the case where there were different organic compositions of capital, we can see what happens.

4.   The difference between human and animal sensitivity to scents is thus explicable mainly by the different composition of their brain-air.

5.   The fourth question with which I started this chapter concerns the maintenance of a different chemical composition in different places.

6.   They weld together mineral grains of radically different compositions and properties, rendering most techniques of mineral separation and enrichment ineffectual.

7.   This distribution leads to a very different ethnic composition of the population in different areas of the country.

8.   Fortunately, the incoming melts and the chamber walls often have significantly different isotopic compositions, so that their respective influences can be detected.

9.   This largely reflects the different composition of the case load, with fewer householder proposals, which almost always lack policies.
