As one moves through the state of michigan, there is a change in predominant trees species. there are hardwoods in the south (a.): pines and spruce in the north ( the opposite is true for the state of georgia. there are pines in the south (coastal plains) and hardwoods in the north (piedmont). what is/are the key determining factors in this tree species distribution? a) elevation and temperature b) average annual precipitation c) soil type and available water d) biodiversity of animal species

A) elevation and temperature Explanation:Due to the mountains-to-the-sea topography of Georgia, Georgia has a wide spectrum of natural vegetation. Trees ranges from maples, hemlocks, birches, and beech near Blairsville in the North to cypresses, tupelos, and red gums of the stream swamps below the fall line and to the marsh grasses of the coast and islands.Exploitation of these trees for pulpwood is a leading economic activity in Georgia.

On the other hand, Michigan's tree distribution is determined by climate, soil and topography effect.

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 answer to your question is:

c. complementary base-pairing
