Please Explain two ways nitrogen gas in the atmosphere is changed into nitrogen compounds that plants can use. -Thank you all in advance! I do need this by 9:20 Am Eastern Time tomorrow

Answers

Not sure if this is what your looking for, but hope it helps. Nitrogen gas can be changed into nitrogen compound through nitrogen fixation, which is the conversion of nitrogen gas to ammonia, that are absorbed by the plant to make protein. Another way is through animals eating plants and obtaining nitrogen, which is later released, by decomposes, when the organism dies.

Please select the word from the list that best fits the definition most destructive kind of mass movement

Answers

The most destructive kind of mass movement a landslide.

What is mass movement?why landslide definition most destructive kind of mass movement?

  • Mass movements are downhill events that transport sediment and other debris, and there are four types of mass movement that have varying degrees of destructiveness. They are landslides, flows, slumps, and creep.
  • The four types of mass movement include landslides, slump, creep, and mudflows. Landslides occur when masses of soil and rocks move down a steep slope.
  • The most destructive type of mass movement is a landslide, which occurs when rock and soil slide quickly down a steep slope. Some landslides may contain huge masses of rock, while others may contain only a small amount of rock and soil.

Landslide is the most destructive kind of mass movement.

What is the acceleration of a vehicle that goes from 70 m/s to a stop in 35 s?

Answers

u=70 , v= 0, t=35, a=?
v=u+at

Use Newton's first law of motion to explain why air bags in cars are important during head-on collisions.

Answers

Newton's First Law of Motion, or the Law of Inertia, states that objects at rest will stay at rest, or object in motion will stay in motion, unless acted upon by an outside force. Therefor if a person is riding in a car going 80mph, and the car crashes head-on, the car will stop, but the person will keep moving at 80mph until it too is acted upon by an outside force, in this case the air bag. If there was no air bag, the person would collide with the car's dashboard or windshield.
