Which event shows conditions that lead to natural selection? A-Weeds are removed by a gardener from a public park

B-Wild horses are tamed over many years and selectively allowed to reproduce.

C-A crab produces millions of offspring in a year, but few survive to adulthood.

D-Farmers collect the largest corn seeds to plant in their fields the following year.​

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?

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.
