Eukaryotic cells have mitochondria, membrane-bound organelles where ATP is produced. If prokaryotes lack membrane-bound organelles including mitochondria, how do they produce ATP? A. Prokaryotic cells synthesize ATP by using portions of the plasma membrane.

B. Prokaryotic cells use GTP instead of ATP.

C. Prokaryotic cells generate ATP by breaking down old pieces of DNA.

D. Prokaryotic cells ingest the ATP they need from their environment.

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.

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.
