Answer:
Nitrogen fixation is the modification of nitrogen present in the atmosphere into a combined form (e.g ammonia) via chemical and some biological action (microbes like soil rhizobia).
Human processes, e.g fertilizers production and fossil fuels consumption, have majorly affected to a high amount the level of fixed nitrogen in the Earth's ecosystems. It is believed that the level of nitrogen fixed by human process will be much more than that fixed via microbial processes involving diazotrophs such bacteria as Azotobacter and archaea as effected by enzyme nitrogenases.
The rate amounting from nitrogen fixation is believed to be 140 teragrams (Tg) of nitrogen per year (1 teragram is equivalent to 1 million metric tons). This amount is very small when viewed to the level at which human factors or means of contribution increases nitrogen amount to the environment.
Because it's extremely dangerous and kills things
Answer:
The correct answer is : increased blood pressure.
Explanation:
The renin-angiotensin system in the regulation of blood pressure. Angiostensin II is the principle hormone in the renin angiotensin system that leads to the vasoconstriction and elevation of water retention and sodium which finally leads to the high blood pressure.
RAAS is the system initiate in stress as it promotes oxidative stress in the brain. Angiotensin 2 ultimately increasing sympathetic outflow and increase to high blood pressure.
Thus, the correct answer is - increased blood pressure.
I am going to say A because a cell makes up matter of the tree so when it duplicates it makes the tree taller..
Please tell me if this is correct or not.. thanks!!
