Using figure 9-1, which pairing matches the structures shown in the cell diagrams with the processes that take place within those structures?

The correct answer is D.        E. Photosynthesis and cellular respiration

The right answer is D

Among all the vital functions, two of them are particularly important, because they concern the very existence of life within the biosphere:

*one is the  photosynthesis, which is nothing less than the source of all energy and matter  organic,

*the other is the breath, purveyor of the energy necessary for the functioning of the vast majority of living beings.

i really wish i could answer this question for you

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.
