What is the role of geological uplifting in
Leni [432]

A

The phosphorus cycle is the natural cycling of phosphorus between the spheres of the earth. The element is important in life because it is a significant component of proteins and DNA. It is a very slow cycling process compared to others like nitrogen, carbon and water cycles.

Explanation:

The geological uplifting of this mineral mainly occurs through the volcanic eruption and formation of new crust in divergent boundaries of tectonic plates. This inorganic phosphorus is taken up by autotrophs - such as plants and bacteria- after weathering of the rocks to release the mineral. It is usually taken up as phosphates (PO₄³⁻) and assimilated into organic phosphorus in amino acids and DNA.

A 1-month-old boy has been vomiting for 2 weeks. how is this symptom of gastroesophageal reflux disease (gerd) and pyloric steno
Travka [436]
The answer is "<span>The infant has regurgitation with pyloric stenosis".
</span>
With pyloric stenosis, vomiting becomes noticeably shot, and a little olive-sized mass is obvious in the RUQ; the newborn child is normally eager again not long after vomiting, and in light of the fact that practically zero nourishment is achieving the digestion tracts, the baby has less, littler stools. The child fails to flourish and has indications of lack of hydration. These signs are not related with GERD. Regurgitation can be present with either illness.
