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.
If you redeem an EE bond before it is five years old, you will lose the last three months of interest. EE bonds earn interest for 30 years if you don't redeem the bonds before they mature. So the longer you hold the bond (up to 30 years), the more it is worth. If you've been affected by a disaster, special provisions may apply. All E bonds and some EE bonds have stopped earning interest and should be redeemed.
