<h2>Answer:</h2>
Soil bacteria are mainly involved in four steps in nitrogen cycle.
- Nitrogen fixation
- Nitrification
- Ammonification
- Denitrification
<h3>Explanation:</h3>
- First of all atmospheric nitrogen is fixed by soil bacteria (N2 to NH3/ NH4+, NO3-)
- Nitrification: The conversion of ammonium to nitrate is performed primarily by soil-living bacteria and other nitrifying bacteria (NH3 to NO3-)
- When a plant or animal dies or an animal expels waste, the initial form of nitrogen is organic. Bacteria or fungi convert the organic nitrogen within the remains back into ammonium (NH+4), a process called ammonification.
- Denitrification is the reduction of nitrates back into nitrogen gas (N2), completing the nitrogen cycle. This process is performed by bacterial species such as Pseudomonas and Clostridium in anaerobic conditions.
There are many different types of specialized cells. This means they are modified by size, shape, or function according to their purpose. Specialized cells make up tissues, tissues make up organs, and organs make up the systems that work together to make up our bodies.
The answer is C. Nucleotide
DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
