Answer:
As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what meteorologists and mountaineers mean by "thin air." Thin air exerts less pressure than air at a lower altitude
The sentence can be completed as follows:
"<span>The wavelength range of colors visible to humans ranges from 350 nm to 750 nm. light that most of us perceive as red is at 750 nm."
In fact, each different color is associated to a different sub-range of this range of wavelengths. Approximately, they are:
- violet: 350-450 nm
- blue: 450-495 nm
- green: 495-570 nm
- yellow: 570-590 nm
- orange: 590-620 nm
- red: 620-750 nm</span>
Explanation:
Trains that use magnetic levitation (maglev) are suspended above the track, which greatly reduces friction from the rails and allows the trains to travel between 250 and 300 miles per hour! Magnetic levitation uses attractive and repulsive magnetic forces to suspend and control the speeds and motion of the trains.
A rainbow. Dispersion is the splitting of radiation into it's different wavelengths.
The first one, or A. You can tell because a dominant allele is capital, and a mixed allele (can't remember the technical term). or Aa, still would show dominant traits. So if short hair is dominant, due to long hair being recessive, a punnet square showing GG, Gg, Gg, and g, has 3 out of 4 showing dominant traits.
Hope I helped!
