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.
Two joined cocci are known a diplococci, while four arranged in a square shape are called a tetrad. The Sarcina genus arrange themselves in groups of eight, in a cube shape. The other common arrangements include a chain of bacteria (known as streptococci) or irregular clusters of bacteria (known as staphylococci). The average size of a coccus bacterium is 0.5 - 1 micrometer.
