Wind affects plant growth, reproduction, distribution, death, and ultimately plant evolution. Some of the effects depend on the air boundary layers next to the aerial parts of a plant, across which gas and heat exchanges with the environment occur.
Tungsten (W) has six electron shells. You get this number by counting down to the row the element is on. The row number is the number of electron shells.
The major difference between lactic acid and alcohol fermentation is the products that are produced. In the 'L.A' fermentation, lactic acid and 150 kJ of energy is produced while in alcohol fermentation, alongside the alcohol (ethanol) and the 210 kJ of energy, carbon dioxide is produced.
In lactic acid fermentation:
C₆H₁₂O₆ ₋₋₋₋₋₋₋₋> 2C₃H₆O₃ + Δ150 kJ
while in alcohol fermentation:
C₆H₁₂O₆ -----------> 2C₂H₅OH + 2CO₂ + Δ210 kJ
