The dots represent a bacterial infection. sal was very sick with this bacterial infection. the infection was treated with antibiotics. sal seemed to get well, but in a few weeks, she was sick again. how can this be explained using natural selection?

The Correct Answer is B) The stronger, more resistant bacteria survived the antibiotics and reproduced.

Explanation:

he stronger, resistant bacteria was able to survive the antibiotics and reproduce. As seen in the diagram, the orange-red bacteria survived and were then able to reproduce to make more of that type of bacteria. Another way to describe this is survival of the fittest.

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.

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.
