Suppose that individuals of a particular genetic strain of drosophila melanogaster reproduce at an earlier age than do other strains of this species. as a consequence, they tend to die sooner. which maxim does this phenomenon exemplify?

there is no such thing as a free lunch

Explanation:

The maxim "There ain't no such thing as a free lunch" also known as "there is no such thing as a free lunch" (TINSTAAFL), indicates the cost of decision-making and it's aftermath.

In this senerio, a particular genetic strain of Drosophila melanogaster reproduce at an earlier age than do other strains of this species at the expense of its lifecycle as this will cause a shortage of its lifecycle which is a negative aftermath compared to other strains that do not reproduce early.

the wetland preservation movement began in the u.s. in earnest with the clean water act (cwa) of 1972. although not specifically written to protect wetlands, the cwa is comprised of a series of regulations designed to prevent pollutants from contaminating u.s. waters.

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.
