Researchers performed an experiment to investigate dna replication. first, they synthesized radioactively-labeled nucleotides, which are nucleotides that contain radioactive elements that allow them to be visualized. then, they inserted the radioactively-labeled nucleotides into a cell. when the cell divided, it incorporated the radioactively-labeled nucleotides into its dna during dna replication.

the following image shows the cell's dna before and after replication. the original dna strands are shown in blue and the dna strands with the radioactively-labeled nucleotides are shown in orange.

which statement is best supported by the results of this experiment?

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.

explanation:

a. population growth is decreasing

-2

+4

-10

-3

-8

-3

so the population decreased by 24 because 3+3+8+10+2=26-2=24.

hoped i !

explanation:

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
