The theory of evolution provides an explanation of how organisms have changed over time. Which of the following best supports the theory of evolution
A. Many diverse species share genetic similarities.

B. All modern species have very different genetics from one another.

C. All modern species are genetically identical.

D. Most related species do not share genetic similarities

B. All modern species have very different genetics from one another

Explanation:

The question asks for change over time and the only answer choice that is evident of change would be choice B.

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.
