Please use the following information to answer the questions below.
Diatoms are encased in valves made of translucent hydrated silica whose thickness can vary.The material used to store excess calories can also vary.At certain times,diatoms store excess calories in the form of the liquid polysaccharide laminarin and at other times as oil.The table shows data concerning the density (specific gravity)of various components of diatoms and of their environment.

-Judging from the table and given that water's density and,consequently,its buoyancy decreases at warmer temperatures,in which environment would diatoms (and other suspended particles)sink most slowly?
A)cold pure water
B)warm pure water
C)cold seawater
D)warm seawater

Cold seawater has the highest density, which means it will offer greater buoyancy to diatoms and other suspended particles, allowing them to sink more slowly. The density of pure water and warm seawater is lower, so diatoms would sink faster in those environments.
