Nitrogen-fixing bacteria are very important to other organismsbecause they chemically change nitrogenous compounds that are not usable by living... Why are nitrogen-fixing bacteria essential for life? Most organisms cannot obtain nitrogen from the atmosphere. Nitrogen fixing bacteria take Nitrogen out of...
Termites are oligonitrotrophs and usually thrive on a nitrogen-poor diet. Therefore, nitrogen fixation of symbiotic bacteria in the digestive tract is essential for the survival of termites. This paper reviews the progress of the nitrogen fixation of symbiotic bacteria in termites. Main contents ...
Nitrogen is generally considered one of the major limiting nutrients in plant growth. The biological process responsible for reduction of molecular nitrogen into ammonia is referred to as nitrogen fixation. A wide diversity of nitrogen-fixing bacterial species belonging to most phyla of theBacteriadomain...
Step-by-Step Solution:1. Understanding Nitrogen Fixation: Nitrogen fixation is the process by which atmospheric nitrogen (N₂) is converted into a form that plants can use, such as ammonia (NH₃). This proc
nitrogen fixation is the essential biological process and the initial stage of the nitrogen cycle. in this process, the free nitrogen available in the atmosphere is converted into ammonia (another form of nitrogen) by certain bacterial species like rhizobium, azotobacter, etc. and the complete...
It is thus converted to a metabolically usable form by the process of nitrogen fixation. Answer and Explanation: The correct option is d. Plants fix nitrogen with the help of nitrogen fixing bacteria. Some of these bacteria are free living and some live in......
What are the advantages of seeds being in a dried-out state while they are lying in the soil? Why is it important to reduce the amount of biodegradable organic matter and nutrients during sewage treatment? What are essential trace minerals and why are they important?
Understanding the emergence, evolution, and transmission of antibiotic resistance genes (ARGs) is essential to combat antimicrobial resistance. Here, Munk et al. analyse ARGs in hundreds of sewage samples from 101 countries and describe regional patterns, diverse genetic environments of common ARGs, and...
One-celled organisms that sometimes cause infectious diseases but, very often, are essential to keeping us healthy or are harmless. They come in three shapes, resembling a sphere, spiral, or rod. We generally refer tobacteriajust like that:bacteria. But note thatbacteriais technically the plural...
While in Rhizobium the nod genes are present on a large sym-plasmid, other essential genes must be present on the bacterial chromosome and on other plasmids. Induction of plant genes is evident from the formation of nodule-specific proteins, the nodulins. Though many different plant and ...
