During transcription, what happens to the RNA polymerase if a repressor protein attaches to the operator? A. It begins transcription.
B. It begins translation.
C. It cannot attach to enzyme 1.
D. It cannot attach to the promoter.

your answer is going to be physical weathering

i think it is d. objects resist changes in their state of motion.

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.
