All of the following could prevent a genetic trait from becoming an adaptation except:
A. The failure of an individual with the trait to reproduce.
B. a large change in the abiotic conditions of the environment.
C. the failure of the individual with the trait to pass it on.
D. a reproductive strategy that includes having a large number of offspring.

D) a reproductive strategy that includes having a large number of offspring.

Explanation:

If a reproductive strategy is used and large number of offsprings are produced, this will mean that there will be more chances for the genetic trait to be seen in the offsprings. Hence, option D, is the only option which illustrates how a genetic trait will occur more in the offsprings.

Other options , like option A, show how a genetic trait will fail to pass from the parent to the offspring. When an individual carrying a certain trait fails to reproduce, he cannot transfer the trait as the individual did not produce any children.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
