Jacob is studying cell organelles. He knows that light energy drives photosynthesis. Look closely at the diagram below. What conclusion can Jacob make when he compares the function of chloroplasts and mitochondria in plant cells?

a
A- Plant cells have a membrane surrounding the nucleus. Animal cells do not.

B- Animal cells contain mitochondria. Plant cells do not.

C- Plant cells are surrounded by a cell wall. Animal cells are not.

D- Animal cells contain chloroplasts. Plant cells do not.

C- Plant cells are surrounded by a cell wall. Animal cells are not.

Explanation:

because only C is the correct answer

Hope this help..

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.
