What contains dna but do not contain cytoplasm or ribosomes and a blank is a typical prokaryotic cell

What contains dna but do not contain cytoplasm or ribosomes and nuclear membrane.

Explanation:

Bacteria are unicellular organisms whose nuclear material is not enclosed within a nuclear membrane hence they are said to be prokaryotic. They also lack cytoplasm and ribosomes. They belong to the kingdom Monera. Bacteria lack membrane bound organelles like mitochondria and chloroplasts.

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.
