A short break for a household tip on cleaning white resin chairs. We've had most of our white resin chairs for more than a decade--I'd say 14 years at least. After all that time they're still in good structural shape and sturdy and except for the nasty black stains there'd be no reason to throw them away. We've got six that sit out in the weather 24/7/365.
Another common shape of bacteria is the coccus. Cocci are spherically shaped bacteria that organize in several distinct arrangements when in groups: diplococcus, tetrad, sarcina, and staphylococcus arrangements.
Most bacteria are 0.2 um in diameter and 2-8 um in length. The three basic bacterial shapes are coccus (spherical), bacillus (rod-shaped), and spiral (twisted), however pleomorphic bacteria can assume several shapes. Arrangement of cocci. Cocci may be oval, elongated, or flattened on one side.Cocci may remain attached after cell division. These group characteristics are often used to help identify certain cocci. Cocci that remain in pairs after dividing are called diplococci.rrangement of cocci. Cocci may be oval, elongated, or flattened on one side. Cocci may remain attached after cell division.
