If the reference point is stationary, you can ensure that the distance between the point you are studying and the reference point is constant.
Two kinds of nitrogen fixers are recognized: free-living (non-symbiotic<span>) bacteria, including the cyanobacteria (or blue-green algae) Anabaena and Nostoc and such genera as Azotobacter, Beijerinckia, and Clostridium; and mutualistic (symbiotic) bacteria such as Rhizobium, associated with leguminous plants, and Spirillum </span>
Sample Response: The word “conservation” refers to an amount that is unchanged. The total amount of energy in the universe remains the same. The energy in the universe is in balance.
