The Commodity Classification Standards Board (CCSB) assigns classifications 70, 92.5, 175 and 400 to freight with densities of 15, 10.5, 5, and 1 pound per cubic foot, respectively. Freight less dense than 1 pound per cubic foot is classified as 500. The density is the space the item occupies in relation to its weight. The density is calculated by dividing the weight of the item in pounds by its volume in cubic feet.
Bacteria (/bÃ¦kËtÉªÉriÉ/; common noun bacteria, singular bacterium) constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals.
Usage. Bacteria is the plural form (derived from Latin) of bacterium. Like any other plural it should be used with the plural form of the verb: the bacteria causing salmonella are killed by thorough cooking, not the bacteria causing salmonella is killed by thorough cooking.ore. This modern Latin term is formed from Greek baktÄrion âlittle staffâ; the first bacteria to be discovered were rod-shaped. The word bacillus (late 19th century), a pathogenic bacterium, also meant âlittle rodâ in late Latin.
