Please help! Why do organelles like mitochondria and chloroplasts have their own DNA?

All organelles have their own DNA, and these two demonstrate that property.

DNA is used to code for proteins, which these organelles synthesize.

They are responsible for their own replication and division inside the cell.

They used to be free-living prokaryotes that functioned as unicellular organisms.

Its DNA I took the test

Explanation:

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.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.
