What is an explanation of the nitrogen cycle?
Nitrogen cycle begins like every other cycle in the Biogeochemical cycle.Nitrogen is an unstable gas in it's octet form but the normal Nitrogen is stable so during nitrogenation;which is the formation of free Nitrogen in the atmosphere,nitrogen is being broken down during lightening and thunderstorms so,it becomes free in the atmosphere and can now combine with other compounds.During rainfall,Nitrogen combines with water to form Nitric acids and with sulphur to form NITROGEN SULPHIDE.These two compounds of Nitrogen are then incorporated into the soil during Nitrogen fixation. The soil alone can not convert this Nitrogen into usable or rather consumable Nitrogen so only root noddles of leguminous plants like Beans can convert this nitrogen into usable one because they have nitrogen fixing bacteria like Rhizobium nigricans . But there are also some free living bacteria in the soil named Azotobacter which help in converting this nitrogen in the soil into usable Nitrogen so that plants can use it for growth.When these nitrogen compounds have been converted into usable nitrogen,plants now use it to produce food energy which are later on eaten upon by animals for growth.This process is called feeding like we all know.When these plants and animals die,their dead bodies decay and are embedded into the soil.Micro organisms now eat on these dead bodies.A process called putrefaction.These decomposed matters are later on converted into Ammonia in a process called Amonification by nitrogen fixing bacteria.The same Ammonia is converted into Nitrites and later on into nitrates by Nitrosomonas and Nitrobacters bacteria respectively and some of the nitrates are lost into the underneath soil a process called leaching during erosion by water and the nitrates are also absorbed by plants during food chain a process called Assimilation.The nitrates and nitrites are later sent back into the atmosphere during denitrification which is the reduction of nitrates back into the largely inert nitrogen gas (N2), completing the nitrogen cycle. This process is performed by bacterial species such as Pseudomonas and Clostridium in anaerobic conditions. They use the nitrate as an electron acceptor in the place of oxygen during respiration. These facultatively anaerobic bacteria can also live in aerobic conditions.Without forgetting that during thunder storms,Nitrogen is also sent back into the atmosphere.
Why is nitrogen fixation important to both plants and animals?
Nitrogen fixation is important because it converts atmospheric nitrogen into a form that plants can use to grow and thrive. This makes nitrogen available to animals through the consumption of plants that have been able to utilize fixed nitrogen. Ultimately, nitrogen fixation helps sustain the food chain and ecosystem health.
If a proteins shape is changed it has been?
If a proteins shape is changed it has likely been denatured. This is often a breakdown and rearrangement of the protein.
What grain like structures make and store protein?
Ribosomes are the grain-like structures that make proteins inside the cell. The endoplasmic reticulum can store proteins after they have been made by ribosomes.
How do plants get nitrogen from the atmosphere?
Direct nitrogen fixation is performed by a rather specific kind of organism that probably lived free before the atmosphere began to contain oxygen. Today these are anaerobic bacteria that live in nodules on the roots of plants, particularly the legumes. The actual process is brought about by enzymes called nitrogenases. It is an energy intensive process, requiring a lot of ATP in acid conditions. To fix one molecule of nitrogen requires sixteen ATP molecules and the product is ammonia, which is immediately converted to ammonium ion by acid hydrogen. This is still not available to the plant, but if excreted into the soil other aerobic bacteria convert it to nitrite using oxygen, and then nitrate, and this is available to the plant. Another pathway is to convert the ammonium directly into glutamic acid, which the plant can use directly to generate protein.
How is nitrogen in the atmosphere converted to nitrogen in the soil?
Nitrogen in the air is primarily in the form of nitrogen molecules (N2) with traces of other nitrogen compounds collectively called NOx. Nitrogen in the soil is in the form of nitrates, nitrites, ammonia or protein.
What are two forms of fixed nitrogen?
Two forms of fixed nitrogen are ammonia (NH3) and nitrate (NO3-). Fixed nitrogen refers to nitrogen that has been converted from its inert atmospheric form (N2) into compounds that can be used by plants and other organisms.
What is the difference between fixed nitrogen and free nitrogen?
Fixed nitrogen refers to nitrogen that has been converted into a form that can be readily used by plants, such as ammonia or nitrates. Free nitrogen, on the other hand, refers to nitrogen gas (N2) that makes up about 78% of the Earth's atmosphere and is not readily available for use by most organisms until it is fixed.
What is the difference between free nitrogen and fixed nitrogen?
Free nitrogen refers to the nitrogen gas (N2) present in the atmosphere, which is not readily available for use by most organisms. Fixed nitrogen, however, is nitrogen that has been converted into a form that can be utilized by plants and other organisms, such as ammonia, nitrate, or nitrite. This conversion process is often carried out by nitrogen-fixing bacteria in the soil.
When did Leif Ericson's explorations end?
Leif Ericson's explorations ended in 1003 when he returned to Greenland. He had been to Greenland in 1002 and had converted many of the people to Christianity.
If nearly 79 of the atmosphere is made of nitrogen how could there be a shortage of nitrogen in soil?
Although the atmosphere is rich in nitrogen gas, plants cannot use this form directly. Nitrogen needs to be converted into a usable form like nitrates by soil bacteria for plants to uptake. In cases where the soil lacks these nitrogen-fixing bacteria or has been depleted due to overfarming, there can be a shortage of available nitrogen for plants.

How does the nitrogen cycle works and why it is important to living oranisms?
Nitrogen is the major component of earth's atmosphere. It enters the food chain by means of nitrogen-fixing bacteria and algae in the soil. This nitrogen which has been 'fixed' is now available for plants to absorb. These types of bacteria form a symbiotic relationship with legumes--these types of plants are very useful because the nitrogen fixation enriches the soil and acts as a 'natural' fertilizer. The nitrogen-fixing bacteria form nitrates out of the atmospheric nitrogen which can be taken up and dissolved in soil water by the roots of plants. Then, the nitrates are incorporated by the plants to form proteins, which can then be spread through the food chain. When organisms excrete wastes, nitrogen is released into the environment. Also, whenever an organism dies, decomposers break down the corpse into nitrogen in the form of ammonia. This nitrogen can then be used again by nitrifying bacteria to fix nitrogen for the plants.

Is nitrogen valuable?
Yes, nitrogen is valuable as it is an essential element for all living organisms. It is a crucial component of proteins, nucleic acids, and other biomolecules. Additionally, nitrogen is used in the production of fertilizers to enhance crop growth and improve agricultural productivity.
When will your garnishment funds be returned?
If they have been legally garnished (the garnishment was sanctioned by a court) then they will not be returned.
Can you post a hot check at your register if it has been returned?
No I am positively sure that you cant because it has been returned to the person who gave it to you and he/she has maybe cancelled it.
