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.
Hold or fold older US savings bonds? I have 99 $100 EE savings bonds issued from May 1993 to November 2000. Bonds from 1993 through mid-1995 pay an interest rate of 4 percent, while the later bonds are indicated at below 1 percent. Can the 4 percent rate increase or decrease if I allow those bonds to reach final maturity?
