How are forest fires beneficial to conifers like jack pines

Forest fires are beneficial to Jack Pine trees and other conifers because forest fires release the seeds that are buried within the cones that these trees produce. The majority of these cones produced by these conifers are sealed within a resin, which will only melt at a high temperature. Even though hot, dry days may release the seeds, forest fires are more likely to be effective. Hope this helped.

they are beneficial because when trees die from the forest fire, it acts as sort of a fertilizer for the conifers and jack pines.

the answer is golgi apparatus

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.
