Where do plants obtain their nitrogen? A: Plants absorb nitrogen directly from the air.

B: Worms produce a source of nitrogen for plants.

C: Nitrogen is made during the process of photosynthesis.

D: Plants get their nitrogen from soil bacteria.

D plants get their nitrogen from soil bacteria

Explanation:

I hope its right :)

The answer is D

Explanation:

Plants rely mainly on the combined nitrogen in form of ammonia or nitrates resulting from nitrogen fixation by bacteria living symbiotically in their root nidules

c. movement because i took the test and it lets me review my answers

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
