likoan [24]4 years ago
3 0
Due to the atomic mass, different for every element, hydrogen is the lightest element and it's a gas at room temperature due to its properties like point of  ebollition. iron is a heavy solid because it has a high atomic mass and a high point of fusion(temperature needed to melt it).

In lecture, I mentioned most lakes are phosphorus limited. However, the most severely eutrophic lakes are often nitrogen limited
KIM [24]

Answer:

Phosphorus is essential for growth of plants and other organisms. When concentration of phosphorus mostly from high breeding rate e.g., pigs, cattle etc. rise in water it causes severe growth of plants and algae as well as phytoplanktons. As a results layers of phosphorus start to release phosphorus as well due to positive gradient. These reactions in water are iron-redox reactions that are crucial for the release of phosphorus.

When too much phosphorus accumulates, it produces a degrading growth feedback in plants, algae and phytoplanktons that then shift toward excessive nitrogen available from fertilizers and cause a flip from P to N. Cynobacteria now dominates and denitrification as well as nitrification takes place simultaneously.

Severe eutrophication induces hypoxia in water that cause a major damage to plants biodiversity in the environment.

A decrease in GFR will cause __________.
lara [203]
<h2>GFR </h2>

Explanation:

A decrease in GFR will cause lower Na and Cl ion concentration in the distal tubule

  • GFR stands for Glomerular Filtration Rate
  • The rate at which kidneys filter blood is called the glomerular filtration rate
  • The main driving force for the filtering process, or outward pressure is the blood pressure as it enters the glomerulus which is counteracted to some extent by inward pressure due to the hydrostatic pressure of the fluid within the urinary space, and the pressure generated by the proteins left in the capillaries that tend to pull water back into the circulatory system (colloidal osmotic pressure)
  • The net filtration pressure is the outward pressure minus the inward pressure
