Bacteria
Nitrogen fixing bacteria are those that convert atmospheric nitrogen to different nitrogenous ions and add them to the soil. These bacteria may either be free living in the soil, or they may develop a mutualistic relationship with some organisms, such as the nitrogen fixing bacteria that live in the root nodules of leguminous plants. An example of a genus of nitrogen fixing bacteria is the genus Azotobacter.
This is one reason that the same hormone can trigger different effects in different tissues. For example, epinephrine binds to four different receptors in different tissues-- eliciting a different response from each.
During sexual reproduction, the genetic material of two individuals is combined to produce genetically-diverse offspring that differ from their parents. The fact that most eukaryotes reproduce sexually is evidence of its evolutionary success. In many animals, it is actually the only mode of reproduction.
