Why do pulse plants have nodules in them?
Pulse plants have nodules to help them convert nitrogen in the atmosphere to ammonia that can be used by the pulse plants to manufacture amino acids, proteins, nucleic acids, and other nitrogen-containing compounds that are necessary for the pulse plants to survive.The conversion of atmospheric nitrogen into ammonia is called nitrogen fixation. The nitrogen fixation process starts with the formation of nodules.Rhizobium is a common soil bacterium which invades the roots of the pulse plant and multiplies within the cells of the cortex layer. Within a week after infection small nodules are visible to the naked eye.The nodules grow and turn pink or reddish in color indicating that the process of nitrogen fixation has started.
Nitrogen is biochemically fixed within the soil by?
Nitrogen is biochemically fixed within the soil primarily by certain species of bacteria. These bacteria convert atmospheric nitrogen into a form that plants can use, through a process known as nitrogen fixation. This process is essential for making nitrogen available to plants for growth and development.
Why are The bacteria that live within the roots of a soybean plant are a critical part of of the nitrogen cycle?
The bacteria that live within the roots of soybean plants, specifically rhizobia, play a crucial role in the nitrogen cycle by converting atmospheric nitrogen into a form that is usable by plants, a process known as nitrogen fixation. This symbiotic relationship allows soybeans to thrive in nitrogen-poor soils and contributes to soil fertility. As soybeans and other legumes are harvested, they enrich the soil with nitrogen, benefiting subsequent crops and promoting sustainable agricultural practices. Thus, these bacteria are essential for maintaining ecosystem health and agricultural productivity.
Does nitrogen in the air follow a cyclic pattern and why?
Nitrogen in the air does not follow a cyclic pattern in the same way that some other elements do in biogeochemical cycles, like carbon or water. Instead, nitrogen primarily exists in the atmosphere as dinitrogen gas (N₂), which is relatively inert and does not participate in significant cycles directly in the atmosphere. However, nitrogen does enter and exit the ecosystem through processes like nitrogen fixation, nitrification, and denitrification, contributing to the nitrogen cycle within soil and living organisms. Thus, while atmospheric nitrogen is stable, it is part of a broader nitrogen cycle that includes various transformations and biological interactions.
The main purpose of DNA is to store information. Where is information stored within a DNA molecule?
It is stored within the sequence of nitrogen bases.
What organisms perform nitrogen fixation?
There is a bacterium that resides within the rhizomes - nodules found within the roots - of Legumes that transforms atmospheric N2 [gaseous molecular Nitrogen] into its forms [NO2 and NO3] that are biochemically active.
What is the difference between symbiotic and asymbiotic nitrogen fixation?
Symbiotic nitrogen fixation occurs when nitrogen-fixing bacteria form a mutually beneficial relationship with plants, typically within nodules on plant roots. Asymbiotic nitrogen fixation, on the other hand, happens in free-living bacteria in the soil or water that can fix nitrogen without the need for a specific plant host.
Which parts of the natural environment carry out nitrogen fixation?
Legumes; possess nodules located within their roots that are packed with Nitrogen-Fixing bacteria. So the Answer is: leguminous [root-bound] nodules.

What is a process of pulling apart an N molecule?
The process of pulling apart an N molecule involves breaking the chemical bonds that hold the atoms together. This can be done through various methods such as applying physical force, heat, or chemical reactions. By breaking the bonds, the individual atoms within the molecule are separated from each other.

Is a bond between hydrogen and nitrogen a hydrogen bond?
It depends. In an individual molecule, covalent bonds hold the nitrogen atom to the hydrogen atom. This is a type of a intramolecular force and is responsible for holding the atoms in a molecule together. In a group of NH containing molecules, the force responsible for holding the molecules together is due to is the hydrogen bond. This is a intermolecular force and is responsible for holding the molecules together. So basically, if the hydrogen and nitrogen are in the same molecule it's not a hydrogen bond and if they're not in the same molecule and there's a still an attraction it is a hydrogen bond.

How do living organism live?
it depends on which living organisms you are talking about. Plants absorb it through their roots in the form of nitrate (NO3) or ammonia (NH4) or in the case of Nitrogen-fixing plants, they host a bacterial infection which undergoes di-nitrogen fixation within a nodule and makes the nitrogen for the plant. Many types of bacteria and other microorganisms possess the ability to fix atmospheric N2, which eukaryotes in general cannot do. Animals in general get their nitrogen by consuming other organisms or organic material.
The main purpose of DNA is to store information. Where is information stored within a DNA molecule?
It is stored within the sequence of nitrogen bases.
What are the four main types of metabolism carried out by soil organisms?
The four main types of metabolism carried out by soil organisms are aerobic respiration, anaerobic respiration, fermentation, and nitrogen fixation. These processes play a key role in nutrient cycling and energy flow within soil ecosystems.
