a- sexual selection among rthe insects has changeds the gene pool
b-genetic equlibrium has been maintained

d-indidviduals with new genes have immigrated into the population.

hello there,

igneous rock formed from below the surface would have more crystals because

answer: because magma cools more slowly than lava

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.
