Peter Buri conducted experiments on random genetic drift using about 100 experimental populations of the fruit fly, Drosophila melanogaster, Suppose that in each population the initial frequencies of the bw and bw75 eye color alleles was 0.7 and 0.3, respectively. How many of 100 populations would you expect to eventually go to fixation for the bw75 allele under random genetic drift?

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
