Types of Microorganisms. 1. Bacteria. Bacteria are unicellular organisms, about few microns in size (1 micron (Âµm) = 1/1,000 of a millimetre), consisting of DNA, cytoplasm, structures needed for metabolism and reproduction, cell membrane, cell wall and capsule (Picture 1). Certain bacteria use flagella, tail-like appendages, to propel themselves.
All U.S. savings bonds have a final maturity date when they stop earning interest. Investors often lose track of this date because the U.S. Treasury Department has extended the original maturity of some bonds up to 30 years.
They will continue earning interest until they reach final maturity -- 30 years from the issue date for all EE bonds. --What's the tax implication of cashing a savings bond? Unless you elected to pay taxes on the interest on an annual basis, which few people do, you must pay federal income tax on the bonds in the year they mature -- even if you don't cash them in.
