Answer:
Nuestra alimentacion debe estar basada en alimentos ricos en vitaminas, minerales como las frutas verduras, legumbres y semillas.
Explanation:
Los alimentos ultraprocesados son altos en sodio, conservantes, y pobres en vitaminas, es por eso que deben ser evitados ya que algunos hasta se consideran hasta carcinogenos.
No se descarta los compuestos quimicos ultraprocesados ricos en grasa perjudiciales para la salud ya que fomentan la formacion de placa de ateromas.
Answer:
The air pressure at sea level is about 14.7 pounds per square inch (psi). For every foot above sea level, the air pressure drops about 0.0005263 psi. According to this information, at about what height above sea level is the air pressure 13.2 psi?
This is a physical change, why? Because in order for it to be a chemical change the liquid would have to boil, pop, catch on fire, corrode, cause heat, or make a new substance. Although be careful about the boiling because when water boils it turns into water vapor, thus making it a physical change. Anyways, another reason it's a physical change is because the actually water didn't change. Think of puting salt in water the water may turn a bit into a white color or taste different, but it is still the same substance(water).
Answer:
option D= Thermosphere
Explanation:
Thermosphere:
It is the layer of earth which is present above the mesosphere and below the exosphere. In therosphere photoionization of molecules is occur due to U.V radiations and produce the ions in ionosphere.
Ionosphere:
It is present about 60 - 1,000 Km altitude of upper earth atmosphere and it is ionized part of atmosphere. It is present in thermosphere and parts of meso and exosphere. It is also called the extension of thermosphere. Although it is very small region but having great importance. Solar radiations ionized the ionosphere. It has many important role, for example in atmospheric electricity, creating the edge of magnetosphere and in radio communication to the long distance places of earth. The region present just below the ionosphere is termed as neutrosphere or neutral atmosphere.
Layers of ionization:
At the night significant ionization is occur in F layer but the ionization in D and E layer is not significant. In the day time too much heavy ionization is occur in D and E layer. The F layer create an other layer which called F1 and it is weaker ionization region. The ionization in F2 layer is occur day and night and this part is responsible for reflection and refraction of radio waves.
