Blue-green algae are an example of nitrogen-fixing bacterial that work independently. Independent nitrogen fixers transform less than 5 pounds of nitrogen per acre but are a significant source of nitrogen for rice paddies. In legumes, the nitrogen-fixing bacteria enter the root system of the plant. The infection causes the formation of a node for nitrogen storage. The plant supplies the food necessary to keep the bacteria alive in this symbiotic relationship. In alfalfa, the nodes form into hand-like structures with a palm and fingers approximately 1/2 inch in diameter.

Location is another consideration, as the cost to get your hair colored by a hair stylist at a hair salon can vary widely in different regions. A poll of more than 500 Angieâs List members who color their gray found that 45 percent pay $20 or less for hair coloring. That tracks with the poll's finding that 47 percent of respondents dye their hair themselves. A box of hair dye at your local grocery store may cost between $3 and $20. A Lake Worth, Florida, member pays $50 every five weeks for coloring and highlights. A member in Little Rock, Arkansas, pays $100 to $150 every four weeks for color and cut.
