Key Concepts: 1  Legumes (family Fabales) develop root nodules that harbour Rhizobium bacteria (rhizobia). 2  Endosymbiotic bacteria (bacteroids) convert nitrogen to ammonia (biological nitrogen fixation). 3  Legume crops restore fertility to agricultural soils by capturing nitrogen from the atmosphere.
Benefits of Wearing Gold: 1. Gold has healing property: Pure gold helps in healing the wound and controlling infections in the body. It is said that if a person places a piece of 24 karat gold (pure gold) on an infected area in the body or on a sore wound, the gold helps in reducing the infection.
Rhodium plated finishes are best in class for wearability among the precious metals. Additionally, rhodium is hypoallergenic. White gold normally employs nickel to provide the whiteness of white gold, however, approximately 20% of women will have some form of allergy to nickel. Thus, by rhodium plating, a possible allergen is removed from contacting your skin. The one exception to that is on white gold stud earrings. Because the nut of the earring drags along the post, the post will not remain plated for long. In those instances where nickel may be a problem, we recommend using platinum posts/nuts on a white gold basket, or simply going with platinum earrings. Rhodium plating can dramatically increase the long term durability, brightness and luster of the finish. Because it is a plating, it will wear off over time. How soon depends on how much wear and tear the jewelry item takes.
