Cause nitrogen causes plants to grow very well. I don't think plants can do anything with nitrogen gas, the only way they can get it is through the roots, called fixed nitrogen. In nature the only things that fix nitrogen are lightning and microbes that exist in roots of certain plants. So nitrogen is rare in nature and is a limiting factor in plant growth.

Most fertilizers are made from animal (Cow most of the time) waste. The animal waste is high in animal byproducts which are mostly nitrogen and phosphorous.

Dynamic regulation is required for maintaining homeostasis.Explain how a cellular mechanism that regulates the quantity of a bio
Troyanec [42]

The homeostasis of the human body works like a machine set at a particular standard. If the factors deviate from the standard values, the homeostatic mechanism come into action.

For example, if a cell requires certain protein, the respective genes get a signal and get activated. The cell start synthesizing the protein and when sufficient amount is made, there is a feedback loop, which allows the same protein to stop the synthesis as well. A lot of organs and cellular systems are involved in regulating the synthesis of this protein.

This is similar to the cooling system. If we set the temperature of the cooling system to certain degree, it will start cooling the room till the required temperature is reached. As soon as the temperature is acquired, the system cut-off automatically and the required temperature is maintained.

Which gastrointestinal (gi) change may be found in the client with burn injuries?
Elena L [17]

In case of severe burn injuries, a person experiences a sudden increase in the number of dangerous bacteria in the gastrointestinal tract approximately 32%. The increase in the dangerous bacteria increase the chance of developing gastrointestinal conditions like irritable bowel disease, and other non-related conditions like rheumatoid arthritis and diabetes.  

But in case of less severe burn injuries, the dangerous bacteria accounted for just 0.5% of the bacteria. An imbalance in the bacteria cause long term health consequences, in fact some of the complications could possibly even result in death of a person with severe burn injuries.

In regard to blood circulation, if you begin with oxygen-poor blood that reaches the heart from the body and is pumped through a
andrew-mc [135]

The cycle runs like this:

Deoxygenated blood enters from the body to the heart via the superior/inferior vena cava. It goes directly to the right atrium and down to the right ventricle. From there it'll pass through the pulmonary artery into the lungs where diffusion will happen in the capillaries. Gas exchanges will occur and the blood will become oxygenated and return to the heart via the pulmonary vein. From the pulmonary vein it will enter back into the left atrium and then will give the final pump of oxygen rich blood into the aorta and then into the entire body.
