Achloroplast is a specialized organelle that conducts photosynthesis. its compartmentalized structure supports its function. (a) describe two examples in which chloroplasts and their subcellular structures to provide essentials for members of their biosphere. (b) in a scientific study, scientists insert chloroplasts into an animal cell by regulating its lysosomal activity. how would advancements in this study benefit animals?

b

is correct hope this   also i learnd this in middle school

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.
