a.) It has failed to adapt to its habitat during its lifetime.

b.) It is smaller and less brightly colored than others.

c.) It has a shorter lifespan than others of its species.

d.) Its phenotype is less suited to its environment.

and after water is usually warmed by the sun the water temperature raises and then evaporates .

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.
