22.) when surveying the number of individuals in an area you are collecting data on the

b. geographic distribution
c. age structure
d. growth rate
23.) when looking at the area that is lived in by a population you are researching the:
a. density
6. geographic distribution
c. age structure
d. growth rate
24.) when organisms are moving into an area scientists call that:
a. immigration
b. emigration
c. migration

b is the best answer for this question.

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.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.

ya the other dude is right
