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.
Thus, if you buy a $50 savings bond for $25 in 2015, you will be able to redeem it for at least $50 in 2035. Here are a few more important details: You can cash in a Series EE bond after it is 1 year old. If you redeem a Series EE bond before it is 5 years old, you will incur a penalty of 3 months' interest. When the bond matures 20 years after it is issued, the U.S. Treasury will reset the interest rate, and extend the maturity by 10 more years.
