Without genetic variation, some of the basic mechanisms of evolutionary change cannot operate. Consider the three primary sources of genetic variation. 1. mutations
2. gene flow
3. sexual reproduction
Review the diagram involving meiosis and fertilization. In all three scenarios, other than the principles governing meiosis, what is the source of genetic variation?
A) mutation
B) gene flow
C) nondisjunction
D) random assortment

1.the evidene of the reaction

2.yes

3.yes

9.9 years

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.

the correct answer is c   with the systems
