2. The midnight sun or polar day is a natural phenomenon observable in the north of the Arctic Circle and south of the Antarctic Circle, consisting of that, on dates close to the summer solstice, the Sun is visible 24 hours a day.
3. The energy makes the air particles move faster, they collide with others that are at a lower temperature, that move more slowly. As they collide, fast particles yield some of their energy to slower ones. These in turn collide with other adjacent particles. This process continues until the energy is extended to all the particles of the air that was initially at a lower temperature. Finally they all reach the same kinetic energy and consequently the same temperature.
As the stomach contents pass from the stomach to the small intestine, their acidity is rapidly neutralized by the addition of HCO3- produced by the pancreasa good thing, too, because the mucosa of the small intestine has no other protection against HCl.
Amino acids have various prominent functions in plants. Besides their usage during protein biosynthesis, they also represent building blocks for several other biosynthesis pathways and play pivotal roles during signaling processes as well as in plant stress response
