Molecules such as glucose and amino acids can be absorbed from the digestive tract and a renal tubule by the process of facilitated diffusion, which involves a carrier protein that can transport a molecule across the cell membrane down its concentration gradient. The process involves a process of spontaneous passive transport of molecules or ions across a biological membrane via specific trans-membrane integral proteins.
Answer:
The particles that cause the aurora are energized in the magnetosphere, that is, above the atmosphere. If they don't reach 10,000 volts, they will still cause auroral light. The lower energy won't change the wave length of the light, but will cause the light to be dimmer.
