9 Which process is an example of facilitated transport?
AA carrier protein moves water across the cell membrane against the concentration gradient.
B A protein embedded in the cell membrane allows glucose to move to a region of lower concentration.
Waste materials from cellular processes are moved to a region of higher concentration outside the cell.
The cell membrane wraps around a large molecule and forms a a vesicle that takes the molecule into the cytoplasm.

the answer would be   10%

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.
