Multiple Choice

The next few questions refer to the following description and Table 25.1.
Diatoms are encased in Petri-platelike cases (valves) made of translucent hydrated silica whose thickness can be varied. The material used to store excess calories can also be varied. At certain times, diatoms store excess calories in the form of the liquid polysaccharide, laminarin, and at other times as oil. Table 25.1 shows data concerning the density (specific gravity) of various components of diatoms, and of their environment.
Table 25.1 Specific Gravities of Materials Relevant to Diatoms
