Susan is a geological researcher measuring the rate of removal of phosphorous from sedimentary rock during the phosphorous cycle. what process is susan investigating? mineralization eutrophication weathering decomposition

The correct answer is weathering.  

The dissociation of soil, rocks, and minerals, as well as wood and artificial components via exposing with the atmosphere of the Earth, biological species, and water, is known as weathering.  

In the phosphorus cycle, the phosphorus moves in a cycle via water, rocks, sediments and soil, and organisms. In this cycle, with time, the process of weathering and rain makes rocks to discharge phosphate ions and other minerals. This inorganic phosphate then gets dispersed in water and soils.  

The answer is weathering.

Weathering is the breaking down of rocks, soil and minerals as well as artificial materials through contact with the Earth's atmosphere, biota and waters.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
