What method(s) do plants use to obtain nitrogen? Select all that apply.
elena-14-01-66 [18.8K]

Answer:

Plants can't use N2 as is so the first option is wrong. They do have relationships with bacteria that live in nodules of the root and convert the nitrogen into ammonia, a usable form for the plants. So the second option is correct. There are bacteria living in the soil as well that convert nitrogen to ammonia so technically option 3 is also correct. Again, nitrogen if present in water would be in the form N2 which is not usable by plants so 4 is wrong.

These are correct:

use bacteria to convert nitrogen to usable form

In obtain usable nitrogen compounds from the soil

Ainsley lives in a town 360 miles directly north of Orlando. One Saturday, she takes the train from her town to Orlando. The tra
MakcuM [25]
Take note that the total distance that needs to be traveled is 360 miles. The train is moving at 60mph and 2.5 hours have passed. To get the remaining distance, first you need to solve for the distance traveled already. 

Distance is equal to the velocity times the time travelling or:

d = vt

So considering the given we can get the distance traveled in 2.5 hours. 

d = vt
d = (60mph)(2.5h)
d = 150miles

So far, Ainsley traveled 150 miles. If her town is 360 miles away, you can get the remaining by subtracting the distance already traveled from the total distance. 

360 miles - 150 miles = 210 miles. 

Now if you want to put that into a single equation you can do that by combining all the equations together.

d = 360 miles - (vt).
d = 360 miles - (60mph)(2.5 h)
d = 360 miles - 150 miles
d = 210 miles
