>The nitric oxide so formed then reacts with more oxygen to form nitrogen dioxide. Nitrogen dioxide so formed, gets washed down by rain and forms nitrates and nitrites in the soil. Plants absorb these of nitrates and nitrites from the soil and convert them into plant proteins. A..

A binomial experiment should satisfy which of the following requirements? I. Each trial can have only 2 outcomes or outcomes that can be reduced to 2 outcomes. II. There must be a fixed number of trials. III. The outcomes of each trial must be independent of each other..

: Rhizobium, a nitrogen fixing bacteria present in the roots of leguminous plants, fixes atmospheric nitrogen to the soil. Azotobacter and Clostridium are other free-living nitrogen fixing bacteria. Physical fixation When nitrogen..

The nitrogen cycle is complex as it depends on the activities of various bacteria. Nitrate in the soil is built up by plants into protein which is then passed on to animals, which eat the plants. The nitrogen from the protein is returned to the environment as ammonia (ammonifica..

Identify the correct statement / statements. 1. A space is the set of all points. 2. A line is a set of points that extends in two directions without end. 3. A point is a location in a plane with fixed dimensions. => 1 only or 1 and 2 only or 3 only or 2 and ..

Conversion of nitrogen into compounds is essential by combining with carbon, hydrogen and oxygen before it can be absorbed by the plants. This is known as nitrogen fixation. The micro-organisms which can fix atmospheric nitrogen can be classified into two mai..

The process is the transformation of gaseous nitrogen into nitrates by living organisms. Biological nitrogen fixation occurs by: a) Symbiotic nitrogen fixation, which is brought about by certain bacteria such as: i) Rhizobium species in the root nodules of legumes (pe..

During N 2 fixation, atmospheric N 2 is fixed into organic compounds (like amino acids, proteins, nucleic acids) in living organisms, via inorganic forms such as NH 4 + . In nitrogen fixation a large amount of energy is required to separat..
