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?
A. Several proteins are involved in DNA replication.
B. The two DNA strands are replicated in opposite directions.
C. Cell division produces four identical DNA strands.
D. DNA replication is a semiconservative process.
D. DNA replication is a semiconservative process.
I hope this helps

12) several teeth were found in an area of flat land covered with trees and plants. the teeth were examined by a paleontologist, and it was determined that the teeth came from a shark. they found many other shark teeth in this area. however, the people who discovered the teeth were puzzled, because there was no source of water near where the fossils were found. what is the paleontologist's best explanation for why the teeth were found in this area? a) sharks used to live on flat land. b) this area was once covered with salt water. c) this area was once covered with freshwater. d) someone buried the shark teeth deep in the ground.
